Installing these items was an absolute breeze, and now we were ready to get to testing. This is essential for suppressing the M1A. This replaces the factory gas plug, allowing the user to fine-tune the amount of pressure in your SOCOM M1A’s gas system. For this task, I went with the Schuster Manufacturing SOCOM adjustable M1A Gas System. Now that we can physically attach our suppressor, let’s talk about adjusting the gas system so that the rifle cycles reliably. On the range is where you discover if the system is reliable, if your impact point changed and how the additional weight may affect your stance. They are made in the USA from hardened billet material and are the real deal in my opinion. Once installed and aligned, a set screw positively retains the adapter. Their M1A SOCOM muzzle thread adapter uses two separate components and registers directly onto the barrel threads and thread shoulder, thus ensuring proper alignment. The Delta P Design muzzle adaptor allows you to thread on an appropriately sized suppressor. They have created an extremely high-quality muzzle adapter for the family of M1A rifles. The task of attaching the actual suppressor to the M1A was made quite simple by the fantastic people over at Delta P Design. Now that we know our two hurdles, we can talk about the items I used to get this beast purring. When properly adjusted, the M1A rifle can reliably run a full-size sound suppressor. Rightly so, as they are slowing down the gasses leaving the barrel, which in turn suppresses the report of the round being fired. This is problematic for suppressors as they create a lot of back pressure. The M1A was tuned specifically for reliability and accuracy, not adjustability. The M1A vents gas out of a port near the muzzle that faces downwards, bleeding off excess gas as the bullet leaves the barrel. The author demonstrates how the M1A can be suppressed with the use of a Delta P Design muzzle adaptor. The gas system is fixed and non-adjustable, and the muzzle threads - or lack thereof - are not standard 5/8×24, which is what is needed for most muzzle devices. I would take my Mini 14 GB over a M25 any day of the week.How can you make one of the all-time coolest guns in history even cooler? By adding a suppressor, obviously! Now, you might be saying, Jeremy I rarely see suppressors on the M1A why is that? I am glad you asked! In this article and video above I’ll be going over how exactly we accomplished this task, some benefits and some of the downsides.įirst off, let’s understand how the M1A operates. The M1A line was never designed from the factory to be suppressed. Nor do I wan't to worry about where I am going to get M118 or TAP when the world ends because my rifle is all grief with no payoff minus specialty ammo. When I am running from the mongol hoards, I don't want to have to be worried about hurting my fragile rifle. People don't scream bloody murder about SOCOM inaccuracy because they were smart enough to know it wasn't going to shoot MOA or because they didn't and they are embarassed about it.Ill take a Mini 14 or M1A that shoots 4-5 MOA all day long with whatever garbage I can chamber rather than a 1 MOA gun that is finnicky with ammo and requires much attention and special treatment. Somewhere along the line, people got the notion that only sub MOA guns are up for combat or SHTF, when actually its the opposite. If your rifle will fire, reliable enough to keep doing so and accurate enough to hit a torso at 100 or 200 yards most of the time, your set. My point is that in combat, its not MOA that matters. An AK in sub-Sahara Africa would be lucky to shoot 6 MOA, depending on condition and uld be more like 5 or more like 8. The AK47 is the most proficient and widely used assualt weapon in the world and it has killed millions. While its possible to shoot 1 moa with a Mini 14 or M1A, it comes at a great cost both monitarily and in reliability. The M14 is not the be all and end all of semi auto rifle accuracy, nor is anything derived from it. I have shot several M14's ranging from stock to A1 and M25 specification and the most accurate rack grade M14 shot 4.5 MOA with M80 ball. Forget the SOCOM series, focus just on the Standard M1A, which is equivalent to an M14.
