LWRC M6A1-S.

The M6A1-S Patrolmen’s Carbine has all of the standard features found in our more expensive models; Our patented self-regulating short-stroke gas-piston system, NiCorr treated hammer-forged barrels, and nickel-boron coated bolt group to name a few. The M6A1-S (“Stretch”) model also features our mid-length piston system, providing a more direct recoil impulse for faster follow up shots. Self-regulating short-stroke gas-piston system eliminates the venting of hot, carbonladen gases into the receiver and bolt carrier group, thus eliminating the intensive cleaning regime of rifle. It also means the bolt carrier group and associated springs are not subjected to the searing heat of the tapped gases, this being one of the major causes of small parts failure. This translates into carbines that are far more reliable than the legacy direct impingement carbines, regardless of user maintenance. Another benefit of short-stroke, gas-piston system is the improved handling characteristics of weapons over the direct impingement legacy weapons. Recoil is lighter and muzzle rise is greatly reduced. Amazingly, this is accomplished in a carbine that is ergonomically identical, weighs almost the same, and retains 80% parts commonality with the legacy direct impingement carbine. The components of LWRC piston system are machined from SPS alloy, a material that belongs to the superalloy family. These superalloys are found in the aerospace industry such as in the blades of gas-turbine jet engines. It is their ability to withstand extremely high temperatures without losing their strength or becoming fatigued.
