Customer Reviews
Got this not to long ago, but I will say it was pretty simple installing it and sure does feel good and looks even better. Already put around 350 rounds threw my gun with zero issues. Would definitely buy again! 5/5.

This is my second Sylvan folding stock adapter. I got the first one about a year ago and put it on a lower shared by a 5.56 and a .300 BO. I like it so much, I wanted one on my 9mm AR. I installed it on the lower and removed the weight from the bolt carrier to fit the extension. I haven’t fired the 9mm since I installed it but, the function check went fine. Now, I have two folding stock lowers for the price of one of the other guys. You can’t beat that.

Great Quality but unfortunately the diameter of the AR9 Bolt Carrier will not fit through it.
If you have any sort of silent capture system, be prepared to go back to the “cha-glunk” of a spring! Bummed.
Love this product. I have one on each AR I own.
