    Schuster M1A M14 Adjustable Gas Plug

    Posted by Starmetal on Nov 28th 2016

    This product performed as expected. I have one on my M1 Garand as well and it makes a difference. On the M1, it protects from bending the long op rod due to the wrong type of powder and loads. On the M1A, it changed how and where the cartridges ejected...for the better. Before they scattered every which way. It also appears to have changed where my groups impacted on the target. They seem to have tightened a little. It's a very good product. Supplying Patriots is a great company to deal with. Their price beat everyone else and their service was super fast. The shipping price was very fair too. I'll be doing business with them again.
