Dual Ambidextrous Control System

The lower receiver features a milled ambidextrous bolt catch slot that accepts the included ambidextrous bolt catch kit, allowing both left and right handed shooters to manipulate the bolt catch and release without shifting grip or reaching across the firearm. The ambidextrous safety selector extends this left and right handed functionality to fire control, enabling shooters to engage or disengage the safety from either side of the receiver. This dual ambidextrous configuration supports complete weapon manipulation regardless of shooter handedness or shooting position. The factory milled bolt catch slot eliminates the need for aftermarket machining or adapter components.

Heavy Duty Pistol Buffer Tube Configuration

The heavy duty pistol buffer tube is designed specifically for AR-15 and AR style pistols, providing a threaded interface for pistol braces or other end attachments. This configuration allows builders to select their preferred pistol brace separately based on individual preferences for adjustability, weight, or specific features. The pistol buffer tube supports standard buffer and spring components for reliable cycling.
