Troy Industries have a great reputation for design and manufacture of weapons components for the US and foreign governments. Their range of accessories for AR15 and M14 rifles has won wide acclaim among private contractors and sports shooters in the US and elsewhere.
The Troy AR quad rail is (in these models) a free floating rail system that gives four U.S. MIL-STD 1913 Picatinny rails for maxiumum versatlity. The AR top rail lines up with the flat top receiver rail to enable the fitting of back up iron sights and do away with the need for heavy M4 cantilever mounts. To install you remove the Delta ring and, in some models, fit a low profile gas block. The two piece construction allows it to clamp around the rifle’s barrel nut without having to remove the existing front sight. Four anti rotation locking bolts clamp the unit securely to the barrel nut, actually enhancing the rigidity of the barrel-receiver joint. Heat is dissipated by large vent holes in the AR rail system and each slot is numbered to enable the easy return of items you have temporarily detached. Push button 360 degree sling swivel receptacles are provided on all models except the MRF-MX. The Troy AR Quad Rail is machined from a solid billet of aircraft grade aluminum and Type III hardcoat anodized in either black or flat dark earth for environmental protection. A Teflon® additive is incorporated to resist scuffing and scratching.
