The most distinct feature of the SL is the barrel. The barrel still utilizes LWRCI's NiCorr surface conversion technology on a cold-hammer-forged barrel, but the barrel is of a smaller diameter to reduce weight.
The SL comes standard with the EXO (nickel-boron) plated Advanced Combat Bolt, one piece EXO coated carrier, and the EXO coated enhanced fire control group. The SL also comes standard with a Daniel Defense A1.5 fixed rear sight and a fixed A2 front sight post.
The SL is a great addition to the LWRCI family of rifles. It provides users with an extremely lightweight rifle that incorporates our patented short-stroke piston operating system, has all of the advanced coatings that make LWRC International rifles some of the best in the world, and does so at an entry level price.
