AGP Arms SIG556 Folding Stock

$130.00

Here is the AGP push button side folding stock for use on the SIG 556. If your model has the AR style threaded buffer end of the receiver, this kit will fit.  The stock features a removable end cap that allows for storage in the tube section.  You are able to store your proper paperwork, cleaning kit, batteries, etc in this section. 

The kit comes complete with the stock and hinge and all the billet adapters to mate with your lower receiver, anti-rotation plug.

Optional 1/2" or 1" butt pad.

Length of Pull:

No Buttpad - 11.75"

1/2" Buttpad - 12.25"

1" Buttpad - 12.75" 

Will not fit the newer 'Classic' model that had the hinge built into the receiver. If your 556 has a factory folding stock, this product will not work.

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.

SIG 556 Butt Stock

Love the new folding butt stock for my SIG 556. It looks much better than the AR style stock that it came with. Feels very sturdy and the folding mechanism is nice and tight, no wobble.

Folding stock for Sig 556

I recently purchased the folding stock for my Sig 556. I purchased this several years ago and was not happy with the stock that it had come with (I was leaving enforcement). The AGP stock arrived recently. It was easy to install and is very sturdy. I also purchased a recoil pad because I needed a longer length of pull. So far it has proven to be an excellent stock. It folds easily and is well made. I highly recommend.
