Custom AR15 Carbine Barrel for Mid Length Gas System
grabcad
UPDATE: STEP214 included.This upload is an imperial pattern 14.5" barrel for the M4 carbine [exploiting a mid length gas system however] or AR15 rifle.It uses a hybrid profile which offers light weight [at 1.6lbs (with 416R Ordnance steel)] while also offering better resistance to heat related deformation through the introduction of heavily vented rear cuts; which also act as a heat sync to ensure maximum consistency. Uses a progressive twist rifling from 1:14" to 1:7".Chambered in 5.56X45mm [Not .223Rem].Pretty simple part, just haven't uploaded for a while and thought I better give the community something.
