Bolt Carrier Group Comparison. LWRC vs BCM

FYI, This video is several years old now. LWRC no longer uses this bolt in 5.56. LMT currently use this design...........A quick comparison of LWRC ACB and BCM Mil-Spec bolt carrier groups. Both are high quality and very reliable. This is just to demonstrate some of LWRC's extra features that are included in its premium price.
