AR stock question

cap6888 · Dec 6, 2015

Not sure if I should put this here or the Gunsmithing thread......

Just got a MFT BULS stock for my AR. It's a commercial buffer tube and I got the commercial size stock. I put it on and it is extremely tight. As in it take two hands and and my feet to move it. The latch is also getting stuck and doesn't want to move. Anyone else experience this or have any thoughts on a fix?

Sounds like you have a milspec stock.

That is what im thinking too.

Unless that commercial Receiver Extension is WAY out of spec or is bent. They do bend if abused.

I was thinking that the stock might have been mismarked. Guess I'll have to get a milspec buffer and check.

Mil-spec=more better. :thumbsup:

Is the end of the buffer angled or 'squared'? If angled, it is commercial. If squared, it should be mil-spec.

I can mail you a milspec stock to give it a test fit.

The buffer is definitely commercial. I'm wondering if the stock was mispackaged.

When I got my stock for my scorpion it was tight as hell but it loosened up a bit with use.

I have a commercial stock you can test with too.

I have found the Commercial is Longer. Mil-Spec is too short for me.

YES, YES, I know.......

Nope. The stock would be baggy if it was a mil-spec stock on a skinny old com. tube. Something's certainly out of spec.

There is only like....what .010 difference in diameter...enough to MAKE a difference, but not a huge amount.
