The problem is, mil-spec triggers tend to have a heavy trigger pull (sometimes up to 8 or 9 pounds) and the gritty take-up makes it difficult to tell where the break will be. This is where the Dirty Bird Single Stage Nickel Teflon Trigger Group comes in. Featuring honed and polished engagement surfaces, a slick and durable Nickel Teflon finish and finely tuned spring rate for the trigger and hammer springs, you get a smooth trigger pull with very little take-up and a crisp clean break at 5 - 5.5 pounds.Dirty Bird AR-15 True Mil-Spec Carbine Receiver Extension / Buffer Kit100% American Made Kit7075-T6 Aluminum 6-Position Mil-Spec Receiver Extension (7075-T6 Aluminum is nearly twice as strong as 6061)3oz Carbine Recoil Buffer w/ Steel Counter WeightsHardened Castle Nut w/ Staking CutsMil-Spec End PlateDirty Bird AR-15 Lower Parts Kit Minus FCG & Pistol Grip100% American Made KitIncludes extra takedown / pivot pin detent and detent springIncludes enhanced polymer trigger guardA2 Style Pistol Grip Assembly
