Note-
For Linear Comps use a 5.5? to 6? Handguard. Generally we use a HG 1/2? longer than the barrel.
Note-
Usually H to H3 buffers are used. For PDW stocks we have used the JP Std and Heavy types both seem to work the same.

Best backpack gun barrel
Barrel functions flawlessly with the right ammo. You can see the quality of the fit and finish. Gas port is sized for subsonic ammo. If you choose to run supersonic ammo you will need an adjustable gas block or light supersonic loads. Factory supersonic ammo may run very hot, requiring some heavy buffer weights, if you don't have an adjustable gas block.
