This Lewis Machine and Tool bolt carrier group is designed for long term durability and reliability.
The R-LM308DA is the perfect BCG for your LMT MRP-H or AR10 rifle from sub-par equipment.

These BCGs are standard equipment in all of our complete MWS and MARS-H weapons. Works well with both suppressed and unsuppressed weapons.
The gas key has been properly staked to prevent the hardened screws from backing out over time.

Rooftop is the best in the business! As soon as I hit place order I start looking out the window for the delivery! Fastest shipping around and always count on them having things in stock. Plus you actually know what’s in stock and how many! The LMT BCG is as good as you can get. No need to get into the info on it here, but it’s easy to find. Time to hide from the wife and eat my ramen and read the constitution!! Cheers!
