The
AWM rifle is based on the AW with minimal changes to accommodate magnum length
cartridges. It has a detachable box magazine which takes 5 rounds. The normal
cartridges for this rifle are .300 Winchester Magnum and .338 Lapua Magnum.A
muzzle brake is fitted to reduce recoil and jump while acting as a base for an
optional front iron sight.
A fluted, stainless steel barrel is
supplied with the AWM. Barrels in caliber .300 Win Mag AWM are 660mm (26")
long and the length of the .338 Lap Mag is 686mm (27"), both using 1 in 11
twist barrels. Research has found that both produce best velocity and precision
for the caliber without the penalties of weight and length.
