Great product, good quality and perfectly matched to the Sig P556. Very impressed with the build quality and timeliness of the transaction.

Stock is well made, install takes 5 minutes. Feels close to the 552 european folder in length and overall shouldering. Locks firmly in place. No walk or talk at all. Solid! Definately get it with a larger pad. These rifles all have a tight shouldering as is, but it is still a bit short for my stance. Adding a veritcal grip to the handguard does help for anyone experiencing this. The stock folded does not go far enough to lock up on the handguard "nub" on operators right side. I think the proprietary sig ones do, but it is not a dealbrwaker for me. At this price 5 stars. Fast processing and shipping. Would reccomend.

I’m my excitement to install the stock, I didn’t have the threaded plug and stock properly aligned and managed to cross thread one of the mounting screws. The solution was to simply flip the plug over… and make sure everything is aligned!!!

This stock works great, easy to install, and locks up rock solid. Being the tinkerer that I am, I had to do some minor mods…
The locking mechanism was a little sticky. The latch part is aluminum and the bolt that fits into it is polymer. I removed any burrs and polished up the contacting surfaces.
To put the stock into the fixed position, I couldn’t just swing the stock into position. I needed to press the release button to get it to lock in place. My solution was to slightly round off the leading edge of the polymer bolt. Now it locks open easily!

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!

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.

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.

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.

I had several questions about my order and all my answers were quickly answered when i called in. Product was shipped fast and I am extremely pleased with the fit and finish. Will definitely look to AGP for future products.

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.

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.

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.

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