M1 Garand Adjustable Gas Nuts: ORDER HERE
Made from hardened tool steel and parkerized. Service rifle legal! Has the same appearance and configuration as original; CMP 4th Edition #4-13-2-b.
By adjusting the volume of gas in the cylinder you change the speed of the op-rod and the harmonics of the barrel.
If you want to tame things down, it can be opened up just enough to function, or opened fully for single shot functionality.
If you are working on your own hand loads, a quarter turn WILL affect group size.
If you have a 308 Garand this is a necessity if you want to safely shoot heavier 168 grain match bullets.
Also a must have if you hunt with your CMP Garand but want to shoot heavier 30-06 loads. Includes instructions and the adjustment tool (Allen wrench). Made in the USA. Lifetime factory warranty.
Please Note: This accessory is not legal for As-Issued matches.

M1A/M14 Vented and Bored Gas Plug:ORDER HERE

Includes instructions, cleaning drill with handle and tip cleaning wire. Made in the USA. Lifetime factory warranty.
