Ratings & Reviews
Sylvan Arms folding stock adapter
Very well made and priced right. See no difference in quality between this and the more expensive folder out there for twice the price. Will buy again.
This is a very good value. But there is one issue - it will effectively increase your reciprocating mass by over an ounce. The reason is that the standard bolt carrier extension that comes with the kit is nitrided steel. It weights about 1.4 ounces. That's like adding 1.4 ounces to your 3 oz. buffer. They do offer an aluminum one for less than 10 bucks. I needed one for a .300 BLK build to properly cycle subs in a backpack gun.
Good, not great

I bought one. Was happy with it, so I bought another for my other AR. Strange. The first one folded completely open, so stock was parallel to barrel. Second one, not so much. Would not fold completely flat. Also, after a few hundred rounds they both jiggle a little bit, which is probably not a huge deal. But still, it’s a little unnerving to feel & hear your gun jiggle as you’re shouldering it. Next time I think I’ll give the Law Tactical folder a try instead

Bought this as opposed to other higher priced options out there and have to say I'm impressed. Has worked great, excellent value, and will get more of these in the future!

I put this on an AR pistol for the obvious reason. Installation was a bit of a pain and it works as advertised but the 4 stars is for the open position. I would like for there to be more positive lock to hold it open. If you shake the weapon a little, it comes unlocked and the stock swings away. No biggie.....I still like the addition.
