Bolt Carrier Groups

Lantac's new BCG is precision machined from 8620 Steel with a shot peened bolt manufactured from Carpenter 158 and Magnetically Particle Inspected. The entire carrier assembly is NiB, Electroless Nickel Boron coated with the patented, advanced UCT EXO process, unlike standard NiB coatings. This offers extreme lubricity with a friction coefficient of .02 and surface hardness of 82-85 Rockwell C.

High quality components and precise manufacturing make Lantac parts ideal for maintaining and upgrading firearms. The durability, reliability and excellent build quality of these parts will ensure years of service you can count on.

Swap this drop in conversion with the bolt carrier group from your 5.56/.223 chambered rifle and you will be ready to shoot .22LR
