It works as advertised - Bootleg Inc Lightweight Adjustable Carrier, AR 15, Stripped, Semi Auto ONLY

Bought this for my AR pistol and shooting with a can. Casings were being ejected to the next county from so much pressure. Some folks had told me to change by springs, buffer, gas system...etc. Decided to just get this and tweek it and solved my issues! You can even adjust this right after each shot. No need to take the BCG oput and readjust like other competitors.
