2 Position Adjustable gas valve for M14

Description

Want to slow down the action, reduce damage to brass, stop throwing cases yards away, shoot suppressed?  Don’t vent excess gas you already let in to the gas system, stop it from coming in, in the first place!

2-Position Adjustable Reduced Flow spindle valve for the M14, developed by Gaard Engineering, does it all.  This replaces the stock spindle valve on the M14 (including sub-variants M1A, M25, Tanker, EBR, etc) and limits gas flow into the gas system when firing heavier loads, or when firing suppressed.  You can shoot with confidence that you are not over stressing the op-rod, or damaging your brass.  Instead of ON/OFF, the valve has two openings, so you have ON/Reduced Flow.  In either position, a set screw accessible without disassembling the rifle can be used to fine tune the gas you let into the action.

This valve is a revision of the USGI version: the slot to rotate between on/off has been moved to the thin end of the valve, and the chamfered head has been flattened.  All this, so a set-screw can be added, coming in from the side to regulate the size of the gas passage from the barrel into the gas cylinder.  A second, smaller opening has also been added, so you can adjust the restricted flow opening, and get a second position allowing more flow for when you remove the suppressor.  Or, if you only want a slight reduction of flow, like if you are shooting 175 grain bullets and just want to slow the action slightly, you can adjust the valve when it is on the larger opening position.

Unlike other solutions that let too much gas into the gas system, then have to vent it back out, this system simply does not let the gas in, in the first place.  Simpler, and better.  And since the part is simpler to machine, it is also cheaper than other solutions.  The valve is infinitely adjustable, from almost fully closed, up to full USGI size, so you can set it to a minimum, where it will not cycle the gun, then open it a little at a time until it just locks the bolt back on an empty magazine.  After that, tighten the lock nut, and you are all set to go, regardless of the barrel length, load, bullet weight, or choice of suppressor.

No modifications to the gun are required: this is a 5 minute drop-in that is fully reversible.

Includes both wrenches needed to adjust.

NOTE: The pictures show an older version that was adjustable, but only had one cross-hole.  The current design has two perpendicular holes, the full size, and a smaller opening, so you can regulate for a suppressor with the small hole, and if you rotate the valve, you can shoot most loads without a suppressor, and without having to re-adjust the valve.  Pictures will be updated in the next few weeks.
