Not ones to sit on their laurels, LWRCI is constantly looking at their weapons and determining ways to improve reliability and streamline the manufacturing process. Their most recent modification is a switch from a two piece bolt carrier with a dovetailed key to a one piece carrier. This enhancement has allowed LWRCI to reduce the number of parts necessary to build their weapons. In addition, there are now no screws to come loose (an extremely rare situation) and no staking is necessary. The initial units shipped with recent M6A3 weapons, but this modification has begun to trickle down to the M6A2 models. In the very near future, LWRCI will also offer an upgrade path for individuals who wish to discontinue use of their two piece carriers. In order to upgrade to the new carrier, a customer would also need to order a new operating rod as the rod was lengthened slightly in order to accommodate the new carrier design.
In addition to the transition to a one piece carrier, LWRCI has introduced a few other upgrades in the not so distant past. First off, instead of using a phosphate or a standard hard nickel finish on the carriers, LWRCI is now applying a Nickel Boron treatment. This treatment is of benefit to the end user in a couple of different areas. For starters, the Nickel Boron has improved lubricity over other standard finishes and has a noticeably slicker feel to the surface. Secondly, the Nickel Boron allows for easier cleaning of the carrier. Along with the Nickel Boron, LWRCI has also incorporated an Over the Beach modification in the form of longitudinal cuts in the pad found on the tail of their carriers. This allows quicker draining of water from within the upper receiver when the weapon has been submerged. The OTB modification actually allows the LWRCI to be fired once the weapon has broken the plane of the water.
It is this sort of attention to detail and forward thinking proven reliability, that has allowed the LWRCI M6A2 to be recently approved by the DEA.
