Justinmd,
I shoot an M6A2 in multigun. Last year LWRC fielded a new one-piece bolt/bolt carrier that improves the bolt and the extractor.
Running the old bolt, I shot 5000 rounds with zero failures to feed and one failure to extract (Wolf Ammo) which was the result of a primer ignition at 95% battery that jammed the steel casing in the chamber. The weapon did not show carrier tilt, but it did have some heavy cam pin wear. The weapon still functioned perfectly after this incident.
I swapped for the new one-piece bolt assembly in case of any microscopic cracks in the bolt head, and have since fired another 3000 rounds with no malfunctions of any kind. I have looked inside several piston guns, including POF, that exhibit carrier tilt marks inside the buffer spring tube on the bottom 180 degrees of the tube. My rifle does not show any wear from carrier tilt inside the buffer tube or inside the upper reciever. I have 3 friends that also shoot LWRC and their guns run equally well with both the old and new bolt designs.
In my opinion, my rifle and the other rifles I have handled live up to LWRC's marketing promises. In my very limited experience, my LWRC vastly outperforms the issued M4s that I have used, especially in terms of reliability.
Very Respectfully,
