DSA para top cover question

slash-5 · October 22, 2005, 19:10

So...

I have a DSA para kit is this the infamous tab on the front? It was not supposed to have one...

In addition, the rear of the cover has another little tab that keeps the whole deal from shutting.

What am I doing wrong?

The rear tab should fit in the vertical slot in the recoil shield of the para-lower receiver. It helps to keep the topcover located. There are a lot of spring forces on the topcover during the firing cycle. I can't tell from your pic if the topcover has the nose or not. Slide the topcover back 1/4" and reshoot the pic. It appears yours either does not have the nose, or your upper has the para cut, but I can't be sure.
Just my opinion....

Here is where it is hitting...

The "standoff" on the top cover should clear the recoil shield on the lower receiver if the recoil shield looks like this.

My lower is from DSA, and it looks like a standard lower.

So.

Should I just file that tab off?

**W.E.G.** · October 22, 2005, 23:12

I fixed the file size and the resolution on that humongous pic.

If your lower looks like this, you can't use a top cover with a "standoff."

I see no reason why you should not remove the standoff.
It doesn't appear to contribute to the lockup of the rifle.

Am I the only one with this problem? I have to believe that others have had this same issue...and I wonder why DSA didn't put that groove in the lower if the top cover needs one?

olsarg · October 22, 2005, 23:54

If that is a DSA para lower the groove should be there . I wouldn't do anything till I called DSA. A para should have the groove and they should be able to get it done. If not do it your self as easy to do the groove as to file off the tab IMHO. the tab was there for a reason.

I have a non DSA Para. The tab on the rear of the dust cover is present like yours. Leave it be. Is it possible that the lug on the rear lower side of the upper receiver can't engage the retaining catch in the lower receiver?

Nope. I have been using the para with the scope mount which has no tab...The catch works fine.

I shaved off the tab. Sorry guys.

It seems to close fine now.

just an FYI. My DSA alloy para lower did not have the notch milled in it. I put one in it myself with a small file and patience.

It is my understanding that none of the DSA para lowers have the notch cut in them. Rich at CGW can also do it for you. I think he gets around $50 for the machine work. Call him, he is a good guy.

Your topcover will function fine without the nub at the back. I myself like everything like it was originally designed

Rich@CGW · September 17, 2007, 19:45

DSA Para Lowers do Not have the correct slot/groove machined into the recoil plate, for the stand off tab on the rear of the Para Covers. You will have to either grind the tab off the dust cover or machine the recoil plate on the lower.

The front portion of the Cover is a partial nose design.
It allows some containment of the carrier assembly, but should not need any machine work on the upper receiver to accommodate it.

Short route, grind the tab off the back, and you'll be in business in no time flat. You really only need to remove about 50% of the tab, Just enough to clear the existing scallop in the recoil plate.

Geez ! Who hit the switch on the time vacuum ?

I got sucked into that one easy enough.

No kidding!!

But still good information. I'm planning on a para build soon and this info is timely. However, I expect that the use of a DSA HD scope mount will avoid all of these issues!
