The Troy Industries Professional Grade Sling Mount installs over the factory end plate and castle nut to provide two attachment points for quick detach swivels. Constructed of hardened aircraft aluminum with a matte finish. One quick detach 1.25" swivel is included. Does not require removal of the buffer tube for installation. Eliminates the possibility of castle nut rotation loosening your stock.

Great fit QD sling adapter


Bought 2 of these. mounted them on AR 15's. They fit over the castle nut, flush with the receiver. Does not interfere with grip for right or left hand. Easy to install and can be removed if you need to replace buffer tube. Install was a 2 minute jod.



Easy to install. Very solid. Great machining. Functions as advertised and as expected. Dont regret my purchase one bit. As always top notch service from PA!



Great product, does NOT replace factory end plate. As always received product before most other companies even process order!

M4 Front sling adapter


The product works great. Fit quad rail flawlessly. It's exactly what I needed. The delivery was fast, service great. The adapter was a little pricy, but you get what you paid for. Thank you.



There is a huge difference between quality accessory parts to those far less superior!! I liked how Troy's design was made to fit over the castle nut allowing for the full collapse of the butt stock.

Was up to my expectations.


This mount is perfect for AR's with A2-type butt stocks in that it gives you options to attach/quick detach a sling. It creates (in my opinion) the perfect attachment point for a single point or a two-point sling. Easy to install....literally in under a minute. Fast shipping as usual from Primary Arms, my new favorite place to shop for firearm products.
