M1A Vented and Bored Gas Plug


Product Description

This Non-Adjustable gas plug has been bored out 58%, for a larger expansion chamber, and 1/64th hole drilled in the end, to allow a slight amount of gas to escape.  With this design there is an average of 2600psi less pressure on your op-rod. Thus reducing bolt wear and movement between shots. *Cleaning drill and cleaning wire included

  1. Back Again 5 Star Review

    Posted by on 3rd Nov 2020

    Asked, studied, thought and then ordered one and tried it. It worked so well that one month later I'm back for a second M1A Vented and Bored Gas Plug. A great product.

    A precision piece of art.

  3. It works 4 Star Review

    Works as advertised. Seems to reduce the Op rod velocity with higher pressure loads. Need to test to see if it's affecting my loads accuracy Vs. with standard plug.

  4. Cleaning The Bored Gas Plug 5 Star Review

    This is an addendum to my original review, and a response to the other review criticizing the cleaning drill bit.
    Use PatchOut to clean the carbon out of the plug. Swab the inside of the plug with PatchOut and let it sit for a couple hours, or better yet, overnight. Let PatchOut do the work for you.

  5. 5 Stars if not for cleaning tool size 4 Star Review

    Posted by on 7th Aug 2017

    I have started using IMR8208 instead of IMR3031 in my match grade M-1A. IMR8208 produces higher pressure. I can tell by the velocity of the operating rod. The Schuster vented and bored gas plug reduced the operating rod velocity. The rifleā€™s cycle is back to normal with the gas plug. My only issue is that the cleaning drill is too large for the plug otherwise it performs as advertised.

  6. Works Reliably with A Variety of Ammo 5 Star Review

    Posted by on 22nd Feb 2017

    I fired my M1A with some vintage LC, current Federal M80, Prvi Partizan M80 (145 gr), and German MEN surplus. The rifle functioned normally with all of the rounds fired.
    Ejected brass seemed to land about as far away as with the standard gas plug. I also shoot an M1 Garand with a hollow gas plug (Garand Gear) and ejected brass plops down a lot closer. However, the Garand's gas system is quite different, and the M1A's gas bleed cut off piston is subjected to much higher pressure at the gas port than the Garand's.
