    Great product and fast shipping from MT&G! This bolt is high quality and fits and functions perfectly. It was the only .40 bolt on the market that had the removable weight in the rear that I was able to remove to facilitate using the Law Tactical folding stock. MT&G had the best price I could find. Buy without worry!
