LMT's branded product line was developed primarily for the US Government / Professional Market. The civilian market is a secondary benefactor to this program. As such the QC standards and priorities (and features) are very different than that of a commercial market AR15 manufacturer. To the very overwhelming majority of shooters, this is a huge plus in the LMT column. It makes their product and extremely attractive option for a civilian shooter looking for a higher standard of product.
With the primary focus being a quality standard for GI sales, there are some noteworthy differences in the product as you receive it. Specific to the LMT Bolt Carrier Groups (BCGs); they ALL come extensively test fired from the factory. As such, every single real LMT BCG on the market will have significant brass, significant carbon, and significant powder residue on the group. Regarding the utility of the BCG (everything LMT builds is focused on utility); this is a very very good thing.
