Entreprise Brit L1A1 receivers have arrived, a few pics...

[sturmgrenadiere]

They exist! My two Entreprise Brit cut L1A1 receivers arrived today.

This is not a an evaluation, just a “look what finally arrived…”

I’ll leave the technical inspection to the smiths, and it will be a while (a day or two to three years) before I get them built and tested myself.

However, my initial impression is that these are going to be a good addition to the market. i'm excited and happy.

Being a ruthless attention to detail fart, only four things stood out:

1. There is a peculiar machining mark/line across the right side of the magwell (you can see the line). It is actually a little ledge of sorts (it catches your finger nail. Odd.)

2. The inside radius of where the dust cover meets the receiver has some grind marks

3. The bottom front of the magazine well is ever so slightly rough feeling.

4. Not one of my Brit charging handles will fit without having to plane-file the bottoms a tad to make them “thinner”. My early DSA inch were like this too.

All of these are easy fixes with a dremel or hand file. It is just finishing stuff… But it would be nice in the future to have these sorts of details taken care of before the receiver goes out the door given the $400 plus cost.

The lettering is well done.

The barrels threaded by hand with no issue and the upper to lower fit is good. One of my lowers had a little peening of the rails so I cannot get it to fully lock with the upper. But tomorrow I’ll correct that (in case you notice the fit issue with the maranyl plastic rifle).

No comment on headspacing, function, etc, because these are simply mocked up on the kits.

I did not have enough time left in the county to wait for custom serial numbers, but I may order two more with them to have waiting for me when I get back from overseas.

Regards

Ben

I haven't heard from them on mine yet. I'm glad they stayed true to the lettering on the side of the receiver.

[atrav]

What's the finish?
Looks to me like a zinc parkerizing in the assembled pics, but more of a paint in the close ups.

How long was the wait from ordering to receiving?

I'd sure like a DSA receiver, but I don't want to wait six months either...

Awesome!!!

Is it just me, or is the engraving a little "fatter" on one of those?

[gunplumber]

that's great - I just heard mine is shipping today, and as a wonderful coincidence I picked up an EXC Brit kit yesterday.

[Bigger_Is_Better]

Mark,
Did you get an email, call, or pm? I should be getting one of the first also, but I haven't heard anything yet.

[sturmgrenadiere]

Matt, thanks for the correction.

And thanks for the receivers. I barreled each one tonight with no problems. Tomorrow I'll headspace and hopefully have time to test fire.

Regards

Ben

[moses]

Nice camera.

Right front of the receiver is a type one cut not tue inch.

Scoop lighting cut on outside of magwell doesn't have the right taper on the edges, Like the cutter wasn't the same.

Definitely the closet you'll get to a true Brit cut anytime soon though.

[gearlogo]

Me wantum one or two.

[gunplumber]

In a previous thread, Matt explained that the base receiver was the Metric casting, so I suspect the few small areas where the inch has MORE material - such as the web in front of the mag well, the cosmetic external dimensions will not be identical to the early British.

Having just machined 3 IMBELs to British pattern, I have a pretty good knowlege of where they differ, and the mag well front and the locking shoulder area are the most significant.

[Matt(formerly@)EntrepriseArms]

Thanks Mark, that explains it!

We did the best we could with what we had, and used a forum member's demilled receiver and blueprints to make it as close as we could.

As a side note to attempt to stem the flood of phone calls surely to come, those receivers that were sent out to a few select people were for testing and review, not the release to the general public. Those receivers availible for testing were a very limited amount.

We are in the process of making more, so don't worry, and we have kept track of who placed orders and when.

GP, is machining an imbel rec to brit specs a service you offer? Thanks.

No - there are too many issues with it. First, the mag well cut is a freaking nightmare. The cutter is around $100, has to be run very slow - about 200 RPM because it is already heat treated. It takes a very long time. Second, the engraving on the original receiver means I either cannot do all the cuts, or have to alter the cuts. I no longer have the ability to engrave the existing serial number deeper and then do the scallop cut on top of it, so I have to move the scallop cut up. Also, the tooling I have on hand is similar but not identical to the original, so where my side receiver cut give the same impression, the transition radius and "pull away" radius are different.

My engraving machine is primitive and I cannot duplicate the font size and layout as I'd like to (and it runs off DOS, so its very time-consuming).

When I have the money to get a windows-driven program and engraver, maybe things will be different.

So as to not hijack this thread, I posted pics on a new thread.

well done Matt !

ill be calling soon to be put on "the list" ..

[Abominog]

Now I wonder how many people hate Matt?

How many have to tear down their Brit kit on Aussie-style receivers? How much time will be spent that could be put into economic stimuli?

I for one am not happy, now some of my L1A1s are not as correct as they could be.

Lots of musicalFAL to be played my friend! :biggrin:

[fal fiend]

it looks kind of rough to me, u see alot of machining lines & grind marks.doesn't look near as smooth as a dsa reciever.

[sturmgrenadiere]

Ironically, the Entreprise are a lot smoother that some real Brit receivers. DSA makes superb receivers, but compared to all the demill stubs I have, DSA's are a lot cleaner looking than many original receivers.

I am a super attention to detail freak to a fault. But many times I have to remind myself that my expectations sometimes don't match the realities of original parts.

[mrf2]

Thanks for posting the pics Ben, now I have to have one.

Ben,

How many L1A1's do you own? That's just sick.........

[sturmgrenadiere]

All,

A quick note on the service of Entreprise. I have heard others have inundated them with inquiries about the status of these receivers asking why haven’t theirs shipped...

The only reason they got them to me is that I am leaving the country and that I had my order in very early in the deal (with some drama of an FFL dropping the ball, but that's another story).

Bottom line they got them to me as a total courtesy because if I didn't get them now, it probably would have been never (or in three years if they were still available).

So while some may be annoyed or irked that they have not gotten theirs yet, rest easy that they are working on them, and perhaps some of the small quirks I discovered on mine will be worked to get you an even better product. And I certainly appreciate the consideration for my situation given my military orders. It isn’t like I am even going to get to shoot them until 2012 since everything is packed for storage.

Anyway, I am posting this out of total fairness to all parties so folks don’t call them wondering where theirs are if I received mine, for what its worth. It has nothing to do with the falfiles or any inside connections. I simply told them my circumstances and said please, and Lily was beyond courteous in trying to help me out.

Regards

Ben

Fair enough! I'm glad they they were willing to hook you up, as who knows what kind of shape the gun industry, as well as the United States will be in when you PCS back.

I still want one!

I have to say that I am not impressed by what I see, casting flash, poor machine work, Hand ground surfaces with chatter marks, burs. I sure hope that the final product is much more refined.

[101ABN327]

Original British L1A1 receivers are just as bad... All in all Entreprise has produced a pretty good copy!

I do not think that copying poor workmanship is a virtue, some of the things that I see would be very easily cleaned up with a file before heat treating. That bur on the front of the magwell looks like it could cut flesh, the chatter marks above the gas piston cut looks like a drunk with a dremel went to town on it. not very good workmanship. These are things that could be easily addressed. I sure hope that the production receivers will have somebody hand dressing these defects before heat treating and final finishing. Time will tell.........

[moses]

I have seen British receivers up close, they are much nicer than this.

Problem is you can't get one though.

[gunplumber]

Can't you put them through a ceramic peanut tumbler to break all the edges. I had that done on my last run of flash hiders to take the sharp edges off the flutes?

Still haven't seen a receiver and spent a lot of money securing these two inch kits . .. .

Hopefully Entreprise is working the bugs out before they are sent out for some serious inspection and critique.....

[Bladewurk]

These look pretty good!

I hope they are available soon with some smoothing!

I am kicking myself right now for missing this early Entreprise bar stock receivered British Kit for $900.!

look at the smooth lines on that thing!

The new receiver looks alright. Given that everyone uses CNC milling these days, it's hard to understand some of the rough work visible.

[sturmgrenadiere]

Has anyone else received theirs yet?

Thats a big NOPE from what I've heard and seen. I dont think that Gunplumber has even gotten his yet.

Any chance that you guys are going to produce a true Aussie cut receiver? Possibily with custom serial numbers?

NO. I've about given up hope.

'scuse me while I go bang my head against the wall . . ..

The question was for Matt. Sorry if it too off topic for you to comprehend Mark.

Like this is thread is not going to go off topic. Is this thread sacred or something. Has a new rule been posted about not asking something that is OT in a thread? Did I miss the memo?

[gunplumber]

Sorry if after 40 posts and a dozen photographs, as well as a link to where I show each of the British cuts, you still haven't grasped that brit is different than aussie.

Yes Mark I know there is a differance. I asked Matt a simple question. And as usual you blew it out of proporation. I wanted Matt to answer your honor not the unfalable Gun Plumber. See, I am not perfect like you are. I do make mistakes every once in a while.

The question s was. [quote[Matt, Any chance that you guys are going to produce a true Aussie cut receiver? Possibily with custom serial numbers?[/quote]

I don't see why you are have such a problem with a simple question addressed to someone else. Oh now I remember. You have to sitck your nose in where it don't belong.

Buzz off Mark. Your still an asshole and always will be.

ABN101327, I am very sorry to see that you have sided with the great and infalable gunplumber. I though you had more common sense than that.

[101ABN327]

I've sided with no one... My question was directed to Entreprise because they still have no product. They are beginning to look a bit like ORF in that aspec t.

You guys can leave me out you your little banter...

This was the question to which I replied. I did not note in this post "Only Matt may respond" So 'scuze me princess, for pointing out the question itself demonstrates you have not bothered to read this thread - which is about the different brit pattern.

Or you did read it, but your comprehension is so flawed that spoon-feeding you the same data again will not penetrate your fog.

I took his comment as veiled sarcasm.

In the meantime, enough banter before I endorse further violations of my own forum rules.

In otherwords, take it to dumping brass or PM or twitter your personal differences.

Ya know I askes a simple question and you guys go off the deep end.

The orginal question. "Was is entreprise going to make any Aussie cut receivers". I was really hoping that Matt would answer.

GP on the other hand thought that he could answer for Matt.

Mark. Maybe if you would come off that cloud that you lieve on and get dwon to the common folk level you might understand.

I am not that educated on Inch anything. Yes my fault. That is why I asked the question. If it offends you guys then tough sh*t. You can either help or act like fools, your choice. I asked a simple question and you choose to be asshole about it. Especially you GP. So furk all of you.

[moses]

GN, why don't you just get A DSA Aussie cut receiver, they are basically Identical to the real thing.

While you can usually get an Entreprise to work, they are not in the same leauge as a DSA or Imbel receiver.

My FFL said my Brit cut showed up the other day. Ordered in late October, had some custom serial number issues, and finally arrived in early January. Not too bad for a custom serial number specialty receiver....

So there you go, 101ABN. They are not vaporware.

[Slo cat]

I recently got my Brit cut receiver from Entréprise. I am disappointed (actually rather pissed off) about the contour just behind the carry handle cut on the right side:

http://img13.imageshack.us/img13/8913/britcutreceiver004.jpg

The left side contour is excellent. Why couldn't they do the right side properly?

http://img13.imageshack.us/img13/8766/britcutreceiver002.jpg

I am not going to return it, as it took about nine months to get it. It has a custom serial number to match my Brit lower. I will use my Dremel and fix the right contour, then repark. :sad: I had to file off some burrs in the carry handle slot to get my slot filler to fit as well.

Does anyone else have a screwed up right contour like mine?

Slo, I think GM4spd posted a clear photo of the proper milling of the right side and it would appear to be an excellent resource to use when reconfiguring the area. Also taking back the front of the magazine area appears simple, if necessary.
Are you planning to use a cutter or grinding stone?

I was disappointed with my custom serial number being off alignment and lightly engraved versus the standarized text on the receiver.

I will used some grinding attachments on my Dremel, since a file won't work. I find these grinding attachments work on curved surfaces the best for me. I also find a sanding drum easiest for fine control. I will try to get a match to the left side contour. I will also work on the front right of the mag well too, as I will be blasting and parking the whole receiver anyway.

My custom serial number is a little odd as well. Some of the numbers are very slightly off size with most, and the whole sequence is not exactly on a straight line. :confused:

Mine are lightly engraved as well.

Best Regards,
Slo cat

[prosecond]

Received mine about a month ago. Serial is lightly engraved on mine too. The contour cut was fine on mine.

[sturmgrenadiere]

Odd because while mine are locked up in a safe in an undisclosed location back in the States, looking at pics of my stuff indicates the two early pre-release receivers I got were correct in this manner.

So an odd and justifiably infuriating discovery.

I still wish Entreprise would have used an inch mold for the model so that the contour of the front of the mag well to the bottom of the front of the receiver would be correct. I would ave gladly paid extra for that. Hopefully some day someone will make something corect for once.
