AGP Arms has a new folding stock out for the 556. Compared to an M4 stock assembly it is said to be 1/2 a lb. lighter (and 6.5 inches shorter folded than a collapsed m4 stock). The LOP is said to be 12.48" on a 556 (like an M4 stock 1/2 extended?). I have no relation to AGP except as a customer. I will post a review when my stock gets here next week. More aftermarket options for the 556=good.




Bad photochop of what I'm looking to do with my SBR and this stock...

I've seen them and they look great for both the 556 and .22 AR's. They need more options for buttpads or offer them with buttpads. Other than that I plan to get one at least.

Is this the all poly version they advertise for the 22LR AR's?

Looks pretty compact.
Yes, it is the same stock but the mounting part is slightly different so you have to tell them that it is for a Sig 556 in your order notes if you get one.

Pretty good lock up on that beast? Another Question is would you be able to use an AR-15 Sling plate with it? Other than that it looks like a great solution to have a slick little folder on the standard lower.

TBD on all counts as I haven't heard about anybody getting one in hand yet (the pics were from an AGP post). Mine will be here in a week. It does look like it has the QD points on the one side of it though. I'm hoping this one is a winner.

Edited to add: AGP just told me that I am the first "Sig guy" to order one. So I'll have to be sure to get a review up ASAP once it comes in.

So, one of these showed up. With this stock, you can actually get a 556 SBR with samson/ Arms BUIS, MFI 552 handguards/ ring, A2 flash hider and no mag down to 6.7 lbs.! That is sick. It uses a metal threaded plug similar to the Ace flush receiver plug. It is super solid extended and has no play folded (hinge friction only but stiff). It has a clever anti rotation plug that goes into the hole under where the receiver plug screws in. The overall length on a 556p based SBR folded is 21" and 29.25" extended with a levang compensator on the front. LOP is real close to the 12.37" or whatever that AGP gave. The stock body is polymer, the plug and hinge section are metal. Weight-just 11 ounces for the entire stock assembly, screws and all. Installation was pretty straight forward and took about 3 minutes.

I played with it for a while and I'm pretty impressed with the stock. It is ROCK solid when extended just like an A2 or something and it doesn't flop around when folded. The LOP is like a Magpul CTR (without a folding mechanism between it and the rifle) extended about 1.5 - 2 positions from fully collapsed.

I can say that this stock is light enough to throw off the balance on any rifles running rail systems with a bunch of attachments.

Accomplice:

Could you post some pics. I ordered one, but have not heard from them as to when it will ship. No com at all other than the initial order received email. I don't have my rifle right now it is being repaired, but I have several parts waiting for it's return. Did you use an MFI 552 handgaurd on yours. If so could you also post some overall photos. Thanks

I don't really have HG's for mine right now. I had found some MFIs that I was going to buy but didn't. I'll post pics when I get some on there.

It looks pretty good on the gun to my eye but it is all subjective of course.

It is def. the most solid feeling folding stock I've tried. No movement at all when extended.

Accomplice: that would be great. I have the MFI 552 handgaurds & ordering the 552 hider. I have the same stock ordered, planning on using that instead of dropping $1000.00 on Classic and SIG SAN folder. Trying to get as close to a 552 as I can with in reason. I lost some faith in the 556 after mine broke and I am struggiling getting it fixed. I have gone back to ARs, I know I SUCK. I will build my 552 look alike and it will become a safe queen. If I hadn't already registered it as an SBR it would already be gone. Anyway, rant over, look foward to seeing the gun up and running.

I'll be the second person to say that this stock is Ugly. It looks rather cheap as well. Looks like some backwoods shadetree type s**t if you ask me. :D

Dem-yeah, I think that this is a another great option for folks that want to avoid having to get a classic lower in order to have a folding stock that matches the lines of the Sig. Not to mention, it probably saves 1/2 - 3/4 a lb. compared to the classic lower.

Stag-yep, it is all subjective. I (obviously) like the look of it. It may be the finish of the composite stock body that makes it's quality seem questionable in pics. I'm not sure. In the flesh it is simple, has good lines, is compact, robust, light and solid. It doesn't have the bare metal inserts in the holes as it appears to in the original set of pics provided by the factory.

The feel and weight of the stock in actuality is great as well. No play like in all of the other options I've tried. Even some non-folding, tube-riding AR stocks have some wiggle.

factory example...

It does look like a sturdy piece. I just wish there was more effort put into the design and look of the stock. It doesn't flow well with the lines of the gun. Also, those sling attach points look rather flimsy. I haven't seen this stock in person so my opinions may not be warranted but like the saying goes, "first impressions are everything".

Anyone know how much this stock weighs? I'm looking to take a few ounces off my SCM with the A2 stock, this looks promising.

Has anyone tried this stock with a Griffin charging handle? When folded it looks like the charging handle would hit the stock when fired...Does it clear the OE charging handle?
