AGP Arms SIG556 Folding Stock

The AGP Arms SIG556 Folding Stock is the perfect replacement for the M4 telescoping stock that comes with the 1st generation Sig 556 without breaking the bank. After seeing comparable stocks for more than twice as much and usually out of stock, and seeing that AGP is here in Arizona, this was a win-win-win! Installation was easy and it works great. Good, snug fit and operation. Highly recommended!

Excellent stock that fits well

I set aside an hour to get this installed on my P556 but ended up only needing 5 minutes. This is an excellent alternative to having to buy a $1,000 lower. The stock does not latch folded, but the latch mechanism works great when folding and unfolding. The stock kind of stays folded by friction. I use mine without any spaces but did buy the longest spacer available with the stock. One down side is that when I tried to put the spacer on the stock the coarse screws included stripped out the screw holes in my stock and I do not see the stock being offered by itself. No biggie, probably my fault for doing something wrong, I'm glad I like it without the spacers.
