m14 gas system unitizing in the GVRD?

I never take it down so far that unitizing it would get in my way, nor can I see a reason I'd want to.

Going from the people I've talked to and what people have said on the various forums, it makes a big difference.
 
When I owned several USGI M14's back in the mid-80's, we discovered that all the gas cylinder assemblys were loose as heck. The USAMTU shooters in Camp Perry solved this rattling problem by drill / tapping / screwing the front band on to the gas cylinder. The US Marines welded (tack'ed) the front band on. Lots cheaper. Then both units would shim the gas cylinder in place.

This rapidly tightened up your groups by reducing the vibrations and vibration pattern into a more predictable and consistent tuning fork-like node/anti-node resemblance.

Most of the Norinco gas cylinders are pretty tight to begin with. This advantage of buying a Nork M14 is quite surprising. BOTH my M14's were very tight needing maybe a 3 thou shim. My SA and Winchester M14's needed between 5 to 15 thou of shims. Wowsers !

Enjoy your Norinco M14 !!

Cheers,

The hardest part of unitizing a Norc is getting off that flash hider. A royal pain if welded on. Otherwise, you need a castle nut wrench and a weird sized allen key to take off the front sight.

Removal of the gas system should not be too tough. Most just need a gentle tap to move. Then insert the shims behind the gas cylinder against the barrel flange and reassemble.

With a bit of trial and error, you want the gas nut to go firm at 4 oclock when looking from the muzzle. A light tapping to 6oclock locks up that gas cylinder against the barrel flange. This really helps consistent accuracy.

You also want to bed the front ferrule/barrel and action to the stock to really see improvements.

I have shim kits and can also offer tuning services but am in the OK Valley.
