Must Have 18/05/2017

Must have part for an m1 if you want to shoot it a lot or don't reload and don't have access to surplus. I'm going to tune mine for modern 180 grain hunting loads, since that's the most common ammo I can get. Better to use new ammo too because it's not corrosive or dirty. If you don't have the tool to change the plugs out, a large flathead screwdriver will work. Set screw is a little tricky to get started, but it works well.

Hard to install Adjust Gas Plug, M1A, 24/04/2014

I bought this product a couple weeks ago to use on my Spfld Arm. inc. M1A and had trouble screwing it in a Military spec. gas cylinder...at first I thought that it was the wrong thread, but a closer comparison revealed that they were correct, just super tight....I used Krills oil on both threads and turning it a 1/8 of a turn at a time using a 1/2" combo wrench it went home....I took the weapon to the range and ran some Tulammo through it. I had to adjust (tune) the valve per instructions and the M1a operated great...it dropped the cases 2 feet away, kinda just barely making it out of the weapon.....no strain on the op rod at all...it is worth the money if you consider how much an M14 op rod cost to replace....

Makes the M1-A and M-1 Garand New Rifles 02/08/2013

I have used the Schuster Adjustable Gas System in both the M1-A and the Garand for several years for general shooting and load developement. It is quite simeple to use. Open the gas adjustment screw to the wide open spot by screwing it out until it is within a turn or two of coming out the front end of the gas valve housing. Shoot a round. Obviously, the rifle is not going to go through its semi-auto functions as the valve is venting all the gas. Open bolt, eject the empty case and lock the action open for safe work at the muzzle! Turn the gas valve adjustment screw inward a couple of turns. Fire a shot. The action may start to work, depending upon the gunpowder you are using and bullet weight. Repeat the process turning the adjustment screw in again. Gently, easy does it! Don't turn too far... As you turn the adjustment screw in and then fire a shot,the bolt may start to come back. Repeat the process of screwing the adjustment screw downward. Fire a shot. This time, the bolt may eject the case and close on an empty chamber. Repeat the process. Now turn the adjustment screw fractions of a complete turn downward. Gently now... The bolt may almost lock open! Repeat the process and this time you may be delighted to find the rifle has performed all the semi-auto functions and is locked open, waiting for the next round. NOW, do not change the setting of the adjusment screw. The rifle should lock open again at the next shot. If it does, you are set FOR THIS POWDER CHARGE AND BULLET COMBINATION. If it does not perform all the functions, turn the adjustment screw downward again and lock it in place with the lock nut the is supplied. Make sure you don't get the allen wrench in so far that as you are adjusting the adjustment screw the same time you are trying to set the lock screw on it! Some fine touch is required for this operation! You will use a little more ammo using this system but you will have a rifle that will operate at minumum impact on itself. Do your chronographing at this point. THEN, REMEMBER TO OPEN THE ADJUSTMENT SCREW ALL THE WAY UP TO START OVER WHEN YOU CHANGE LOADS! Maybe you can figure out a way to reset it to the load you just fired. I have not. I just open it up and start again. I love it!
