Symbolic and Functional
Distinguish yourself and your rifle with the AR-1791s Angular Chevron Magwell design, a subtle recognition of those men and women who have given much, many who have given all in defense of our great nation. The unique magwell design will distinguish your rifle from the sea of nearly identical rifles out there and it provides several significant functional advantages as well.
Oversized Magwell
Designed for faster and smoother magazine changes. Our lower receiver feature a unique tapered design, which results in completely smooth transitions yet still seat firmly. The AR-1791 magwell is optimized for MAGPUL G2, G3, MOE PMAG and ProMag Magazines. Compatible with most aftermarket polymer and all metal magazines.
A Better CQB Grip
The increased surface area of the forward magwell includes milled finger grooves for comfortable and secure support hand CQB, close-in or high magwell grip styles, delivering better weapon control in close quarter environments.
EZ Trigger Adjuster
Included with every AR-1791 Lower Receiver and Lower Parts Kit, the EZ Trigger Adjuster replaces the standard pistol grip bolt. When used in conjunction with Mil-Spec single stage fire control groups (even the cheap ones), the EZ Trigger Adjuster can remove several millimeters of pre-travel, decrease trigger pull weight & provide a shorter, crisper, smoother trigger break resulting in better accuracy & tighter groups
Upper Tensioning Device
The Integrated spring loaded Upper Tensioning Device is fully adjustable without disassembly and delivers tension to the upper receiver, providing a tighter fit between the upper and lower receivers. This eliminates rattle and play between receivers, while also assuring proper alignment of the bolt carrier and buffer tube for better reliability, less noise and smoother cycling
Oversized Trigger Guard
The integrated oversized trigger guard delivers significant additional stability, rigidity and protection for both trigger and finger with or without gloves
Mil-Spec Compatibility
Mil-Spec standard .154″ Trigger/Hammer and .250″ Pivot/Takedown Pins assure compatibility with standard AR-15 uppers, fire control components and accessories.
Takedown detent & spring secured by set screw makes installing the takedown spring, buffer tube, buttplate and locknut a breeze. No more bent or lost springs. Shortened spring, set screw and hex wrench included. Maintains complete compatibility with standard spring & Detent.
