Getting the perfect components to finish your build can sometimes be a pain, especially if you find yourself with parts that you thought should work together that somehow don't when you get ready to assemble your rifle. Take the guesswork out of your next build with a Sauce Pack from Rosco Manufacturing! Each Sauce Pack contains a selection of parts hand picked from their Bloodline hard-use products for when "good enough" just doesn't cut it. Barrel, bolt carrier group, gas tube, and a non-adjustable gas block have all been carefully selected, giving you a quick and easy, highly reliable parts kit that will elevate any build.
