Suppressing the Springfield Armory M1A Tanker 308 Rifle
What happens when a Springfield Armory M1A Tanker 308 Rifle and a Silencer Central Banish 30 come together? Read on to find out!
Info from Sam.S on The Firearm Blog
The M1A Tanker is a part of Springfield Armory’s SOCOM 16 series of rifles and is paying homage to the prototype T26 Tanker Garand developed for Paratrooper and Jungle troops towards the end of World War Two. The Banish 30 is a quality 30 Caliber suppressor that is made of titanium and has a tube extension for all your sound suppression needs. Delta P Design's SOCOM Muzzle Thread Adapter was a huge helping hand in making this dream come true! Below are the specs for the main 2 components.

Other tools used to bring the two pieces together include: Sadlak Industries Gas Cylinder Wrench, a 3/8 socket and wrench (or some other gas plug removal tool), a small flat head screwdriver, and an Allen key set.
Now, here's a play by play of the process:
Starting out front the gas plug underneath the muzzle has to be removed. I used a 3/8 socket and wrench that was thin enough that I could properly loosen the gas plug without harming myself or any piece of the rifle. This plug came out very easily since I only had about 100 rounds through the gun at this point. The gas plug only needed to get started via the wrench and then I could remove by unscrewing by hand.
I would recommend the front sight be removed before or after the gas plug is removed. Take time and care as the hex key on the rear of the sight needs to be loosened and removed and the blade of a flathead gently placed in the space shown in the above photo in order to remove the tritium insert front sight. Do not force anything or you may damage your rifle or your sight.
After removing the front sight, to put on the Delta P Design SOCOM Muzzle Thread Adapter I used the Sadlak Industries Gas Cylinder Wrench to loosen the stock muzzle device on the M1A Tanker. This was the toughest part to remove for me so use caution if you try it yourself. At this point, the muzzle device can be threaded off and the SOCOM Muzzle Thread Adapter can be put on and the process starts essentially in reverse. Make sure when putting on the front sight that your hex screw is tight as mine ended up loosening at the range. I should mention the SOCOM Muzzle Thread Adapter was a perfect fit and I was very happy with how well it functioned as an adapter.
So, how did it do on the range?
This specific M1A variant probably was not engineered to ever have a suppressor on it but thinking like that just makes a person want to try it more. Range time with this gun is plenty of joy without a suppressor but with it? It is intensely cool, I am not going to lie to you. I was caught up in the excitement of going through with all of this when at the range I suddenly remembered that the only missing piece to this whole puzzle would be a different gas plug of sorts. I do not know if someone makes an adjustable one or if they have one specifically engineered for suppression but it would have been a welcome edition given the amount of gas I got to the forehead every time I fired a shot.
The gas back in my face was not too terribly unpleasant and I think the cool factor of it all overcame and made me forget about it. A noticeable side effect of all of this was both the ejected shell casings and the action of the gun specifically got very dirty and fouled up. I shot around 30-40 rounds of miscellaneous ammunition since I did not have any subsonic stuff on hand and the current state of the world made that a difficult thing to track down. The Banish 30 did an outstanding job of making mixed 308 Win and 7.62 NATO ammunition hearing safe although I did opt to have some muffs on after a few concussive blasts of gas hit me in the head which is no fault of the suppressor or rifle but my poor planning.
