Our 12.5" Direct Impingement Rifle run a Carbine gas system for reliability and consistency.
All of our Carriers go through a R.E.M Polish process prior to Titanium Nitride coating.

Our Contractor DI models are fully ambidextrous giving your full control of your bolt catch and mag release from both sides.
All of our Contractor DI Models will come standard with a fully adjustable gas block to give you the ability to find tune your firearm while running suppressor or even while running higher pressure rounds.
This rifle runs our TYPE-A PMC Two-Stage Trigger. Constructed from pre-hardened 4140 this trigger is coated in QPQ to fight against friction and to ensure lubricity. The PMC Two-Stage Trigger ships at 1 1/2 reset to 3 1/2 trigger pull.

The AR10 Platform started as a simple request from a Law Enforcement Department to manufacture a 308 in a short platform for dense populated areas.  So we did just that.  We knew we wanted to stay with a traditional AR10 large frame so we married the Armalite cut with some key feature of the DPMS SR-25.  This is one of the first platforms where weight wasn’t our first consideration.  We wanted a stout and accurate system that had an aggressive stance.

This TYPE-A 12.5 AR10 is built on our all new Ambidextrous Billet AR10 Armalite platform with upgraded mil-spec components to make it an incredibly versatile firearm. The 12.5 Pistol is equipped with a 12.5″ 416R Stainless Steel Lightweight Contour barrel, a 416R Stainless Steel fully adjustable gas block and several options for handguard.  It comes standard with an SILENCERCO ASR muzzle brake to give it that aggressive stance. Fully furnished with B5 furniture, SB A3 pistol brace, Law Tactical GEN3 Folder (optional) and 20 round capacity magazines. The TYPE-A 12.5 Pistol is driven by our TYPE-A Titanium Nitride coated bolt carrier group w/R.E.M. Polish.  It’s also equipped with our improved TYPE-A PMC Straight 2-stage trigger to give it consistent reliability time after time.

NOTE:  All of our pistols are Hardcoat Anodized and then Cerakoted to give you a longer lasting more durable finish.  We wanted your rifle to wear to the anodized finish vs. the raw aluminum surface.  Just another added benefit making your rifle….TYPE-A.
