Enterprise Type 3

Nik · November 23, 2001, 22:06

Just finished building an Enterprise Type 3 $179.00 special on an Imbel Grade II kit. Everything came out fine except there is excessive play between the lower and the receiver. The locking lug on the lower is not properly engaging the lug in the upper. Its the same sort of situation described by GP in his review of the Enterprise receivers.

This is the third Enterprise I've built and all have had the same problem to one degree or another. Its a good product but I wish it locked up tight like the Imbel.

I am assembling a DSA G1 kit on an Entreprise Type 3 Metric and I have no play what-so-ever. I can't get he lower an the upper to move at all.

Nik · November 24, 2001, 22:36

Maybe the G-1 lower is a little wider than the Imbel. I hope so since i got 2 G-1 kits waiting to be built. My STG and R-1 lowers are not nearly as sloppy as the Imbel lower.

i just picked up my G1 kit on the Entreprise$179 type 3. Small aMOUNT OF HORIZONTAL play of upper on lower. Worse however was the hole for the locking shoulder was shaped incorrectly. However my STG58C is fine. Ialso just finished a G1 on an Imbel with a new metric lower from DSA,which came out great.

Thanks for the review, Nik. I'm planning building a couple of grade III Imbel kits on Entreprise type 3 receivers. How excessive is the play between the upper and the lower? Is it enough that you would recommend not using the Entreprise type 3 for an Imbel Build?

Nik · November 25, 2001, 17:21

armedpeasant,

The horizontal and vertical play is really excessive. However it may not be the receiver entirely. I tried the lower on a gear logo Imbel receiver and there was still a little play. Not as bad as on the Enterprise but more than on my STG built on a gear logo Imbel.

Furthermore, when I put the Imbel lower on the Imbel receiver, the latch would not lock up in the same way my STG does. The latch pin was not engaging the receiver lug. It was sliding over it. I tried several different locking pins but the result was about the same.

Based upon this and several other posts I read over at gunsmithing forum, I've come to the conclusion that the Imbel lower is dimensionally different than the STG or R1.

Finished barrelling my G1 on a Entreprise Type 3 today and it came out great.

Timed with a little effort but nothing excessive, in my opinion. Assembled the rest of the G1 because I just couldn't wait to see how it looked and it went together with no problems. Checked for play between the upper and the lower and I can not find any. It appears to lock up solidly. Guess I won't know until I try shooting it. Still need to get the headspace checked.

I'm not so sure it's a matter of different manufactured dimensions, but more a matter of the variability of the dimension per manufacturer, or perhaps the part due to wear, etc.

I miked out some Imbels and found a .10" variation in width of four lowers at the rear (near the recoil plate). You may want to measure yours up. The StG lowers were on average a little wider in cross section and only had a .05 variation over the 4 pieces I measured.

I'm still wondering about the vertical play. I have one Imbel lower that has some play in it with any reciever I have, and I won't build on it because of that.

I don't have any prints, so I am just comparing one to another.

armedpeasant · November 26, 2001, 00:18

Thanks, Nik. I'll try the lower that comes with the kit. If the play seems excessive, maybe I'll get a new stripped lower, and see how that fits.

I HAVE PUT 4 GUNS TOGETHER USING ENT TYPE 3
2 G1 KITS AND 2 IMBEL 1 OF THE G1 HAD SAME PROBLEM I CHANGED LOCKING LUG WITH EXTRA 1 I HAD FIXED PROBLEM ALL THE OTHER GUNS WERE OK I HAVE 2 MORE GUNS TO BUILD AND FOR THE PRICE ILL USE ENTERPRISE AGAIN

Gaspipe,

Thanks for the info. When you think about it .10" is quite a difference. I also thought of something else. My Imbel lower was painted originally. I sand blasted and parked it. The absence of the paint would contribute to it being narrower. I doubt that the thickness of the paint would be .10" but it would contribute some. As for the catch situation, I have no clue. I have 3 other Imbel kits but haven't had the chance to try the different lowers.

Nik · November 26, 2001, 19:06

jwhit,

No need to shout. I believe you. However, none of the 3 Enterprise receivers that I've assembled locked up nearly as tight as the Imbels or DSAs. Those that have assembled/owned either the Imbel or DSA as well as the Enterprise know exactly what I'm talking about.

I hope you mean .010 (ten thousandths) not .10 (one hundred thousandths)!!!
If you can get someone to tig weld just a little weld on your frame lock piece and you can then file it down to where your upper and lower lock up real tight ! this works great! ask me how I know

Gaspipe · November 27, 2001, 18:33

Yeah, my bad - 0.010" variation. Thanks for hitting me in the head and waking me up, Moses.

GALILAR308 · November 28, 2001, 22:19

I tried 4 different lowers on the Entreprise type3. 3 G1's and a STG58. The STG58 was wider than 2 G1's but still alittle wobbly. Finally my last G1 lower locked up tightly.As the rear sight is attached to the lower, I was afraid any noticebile looseness would cause the point of aim to wander.

Nik · November 28, 2001, 22:52

GALIL,

I also tried several lowers and the STG fit the best. However, it still had a little side to side play. Not as bad as the Imbels, but still a little loose.
I think I can drop a few spots of weld on the Imbel lower and grind/sand to fit so as to eliminate the horizontal play. I plan to do the same to the locking pin to eliminate the vertical play. WECSOG all the way baby.

Sumoj275 · November 28, 2001, 22:54

I just tried putting a STG lower on my new Type three and it was tight. Then I tried my G1 lower that will be used for the build and it is tighter than the STG. I am glad, because I have to use a washer to tighten things up on my DSA Factory gun.

Everything that I have put on and tried on the Type III reciever has looked good and I think it will go good. Of course this will be my first build and I am looking forward to getting my WESCOG deploma. I will put it right next to my other degrees!
