so I'm reading up on the LWRC REPR. They claim the barrel will last 20,000 rds!!!
some info from lwrc...
The barrel to receiver interface is almost three 3mes more robust than any other rifle. Barrels
are cold‐rotary hammer forged over a precision mandrel and boast perfect bores that are
consistent in concentricity 0.0002”. The barrel is finished machined in profiles to maximize
accuracy and minimize the adverse effects of barrel whip and harmonics. A target crown is used
to maximize hit probability. The barrel is finished in the NiCorr surface conversion process.
NiCorr is harder than chrome and offers a lower co‐efficient of fric3on adding to barrel life and
muzzle velocity. It makes the barrels easier to clean as they do not foul with copper as readily
and are virtually impervious to corrosion. The material chosen for the barrel is the same used
on the M2 .50 caliber machine gun.
All R.E.P.R.s have high tolerance cold hammer forged barrels made from 41V45 steel, ultra‐rigid
receiver to barrel interfaces and free‐floa3ng hand guards. This makes them capable of very
high accuracy with appropriate match quality ammuni3on.
