    Purchased the Hellfighter from Juggernaut Tactical and made me get rid of my Geissele bolt release for their mag lock so this product allowed me to have my bolt catch back!! works like a charm

    I have multiple magazine lock options but JL Billet has a better finish than all the rest. The fit is much more secure than the others too. The turnaround time was just 4 days! I will be purchasing more JL Billet products in the future.
