The Dirty Bird Carbine Hogue 2-Stage Lower Build Kit includes everything you need to finish your lower receiver, including the brand-new Dirty Bird 2-Stage Trigger Group.
BCMGUNFIGHTER SOPMOD Stock – MOD 0
The Bravo Company Manufacturing BCM Gunfighter SOPMOD Stock Assembly is a strong, lightweight polymer stock for MIL-SPEC receiver extensions. Features a wider body than the standard Mod 0 Gunfighter stock, which provides a more pronounced cheek weld. With its snag free design, there are no sharp edges to tangle the rifle in the sling, MOLLE gear, or other kit. Includes the modular Vehicle Borne Operations Sling Tab. This tab interfaces with a ranger band to secure the sling against the stock when the carbine is not in use.
A color matched rubber butt pad is integrated for secure shoulder placement. A simple 6-part modular design allows adaptable configuration with 1 screw. Ambidextrous sling mounting options available.
BCMGUNFIGHTER Pistol Grip – MOD 3
The Bravo Company Manufacturing BCMGUNFIGHTER MOD 3 Grip provides a reduced angle for improved ergonomics. Each grip features an extended forward tang to close the gap between the trigger guard and pistol grip, and a high rise ‘beavertail’ style back strap. MOD 3 grips are up to a ¼ inch wider than the BCMGUNFIGHTER Mod 0 and Mod 1 grips. A hinged trap door offers storage inside the grip sealed with a water-resistant rubber gasket. Manufactured from high quality, impact resistant polymers, and test fit to ensure proper function.
Dirty Bird 2-Stage Trigger Group
This trigger assembly takes advantage of a two stage fire control design that has been trusted in both competition and combat roles for decades. Springs are tuned to provide a smooth first stage pull of about 1.5lbs and a crisp second stage break at 3lb for a total pull weight of 4.5lbs (actual total pull weight may vary ± .5lb). The 4.5lb total weight gives the operator a greater level of safety and control in high stress environments but with a second stage pull weight of only 3lbs, the shooter can also squeeze off long range precision shots with ease.
