Helpful Positive Review Perfect for Montgo9 by John, Verified Owner, June 13, 2023
Fits perfectly, easy installation, looks clean. Easier to remove and replace brace during these confusing times. The QD mounts on either side are a nice addition. I would highly recommend this product to anyone who shares the same biases that I have.

Most Recent Reviews PICATINNY PERFECT by Bobby, Verified Owner, September 16, 2025
This is being used for an old lower a bufferless 22 I have. The weight of this adapter is nice, it helps balance the feel of a 16" upper and it secures nice and tight with ease. It's a good choice if this is something your looking for.

Product Info for Strike Industries AR Picatinny Stock Adapters

Transform your AR-10 or AR-15 into a rig with a large collection of possibilities by upgrading to a Picatinny stock adapter. These AR15 Stock Adapters from Strike Industries install easily onto your lower receiver to accommodate pretty much any Picatinny-compatible stock or stabilizer on the market. Plus, this Strike Industries Stock Adapter w/ 360 Free Swivel QD Sling Socket retains the rear detent spring for your rear takedown pin, and the adapter is compatible with nearly every major brand of such stock on the market. Since this device only weighs 3 ounces, it won't hinder the performance of your gun - making it a fantastic option for those on-the-the-go who don't need an in-line buffer and buffer spring. While you can install this device yourself with standard handgun tools, you'll need a little help from a trusted gunsmith to fully install this device, ensuring all the bolts and screws match up with your pistol build. Besides from that, this adapter kit includes a Picatinny rail section and a 360 free swivel QD socket to put your attachments on the side of your choice. Pick up yours today to expand your modification with the best-fitting attachment for your rifle.image
