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.
Available in Black

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.

SIG 556 Stock
Finally, a solution to that SIG 556 stock that broke years ago and needed an entire roll of duct tape to hold on. Easy to install, and fits perfectly! Way better than the original.

A must have for non folding 556 classic models
I have finally found the folding stock to put on my State compliant or SCM model 556 classic. It works great and feels good. If you need one do yourself and your rifle a favor and get one.

Light weight
When I opened the package, I was a little disappointed at the plastic stock. It was easy to install and I was surprised how much weight it took off my rifle. Other people had mentioned the same thing in reviews and they were right. Overall, I am happy with the stock and would recommend it to a friend.

Awesome product
Love how this bolts right on to the stock, its almost idiot proof on how to install. Works great, and doesn't feel cheap.
