Troy Industries ProGrade M4 Sling Mount

... IF your buffer tube is actually fully mil spec. About half the tubes being sold only have 1-1/8" of thread. A proper mil spec tube will have 1-1/4" of thread. With a correct tube, if you back the nut all the way, you can tighten the tube to the proper position and still have room to install spring before sliding end plate forward and tightening nut.Troy plate gives me a QD sling mount right where I need it.

Allows for three mounting positions for QD attachments to the lower receiver (left/right/center). Built solidly and matches lower receiver fit and finish perfectly. WOuld highly recommen to those looking for quality sling mount for their QD style slings.

As always Primary Arms has great prices, service and got me this sling mount delivered in 3 days. Great Job!!!

Great sling mount; very nice for AR-15 builds. Primary Arms delivers the best customer service and fast shipping.

Like most every Troy products you get what you pay for. Also, made in the USA.

The Troy OEM sling mount works great and, for me, locates the QD swivel in the best location. I prefer QD swivels for my rifle slings. This mount puts the rear of my sling in a sturdy, out-of-the-way location. It also looks like and integral part of the lower receiver. Have one on each of my black rifles.

The troy sling mount is honestly awesome... It's at the perfect angle, it's super light weight, very tough, and matches the color of the receiver.Downside: Being ambidextrous, it has the knobs on both sides. This sits in line with the castle nut... Which means you have very little room for your wrench. And with what room you do have, it sits cock-eyed. Basically, it's hard to tighten. But doable. Worth the trouble IMO. Much better than Magpuls ambi sling mount (which is noisy as hell).

This sling mount looks awsome on my rifle fits perfectly with no play any were. The only problem was when you finally get the tube screwed into its final position, its impossible to get the spring behind the end plate without twisting it and ruining the spring. There is no room between the sling side wings and the end of the receiver

Troy has great products for a good price. This is very nice with 3 positions and comes with a QD swivel as well. Not bad for $40, PA shipped fast as well.

a little bit tight when putting together but works good
