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!
The author demonstrates how the M1A can be suppressed with the use of a Delta P Design muzzle adaptor.
First off, lets understand how the M1A operates.
TheM1A linewas never designed from the factory to be suppressed.
The M1A was tuned specifically for reliability and accuracy, not adjustability.
When properly adjusted, the M1A rifle can reliably run a full-size sound suppressor.
This is problematic for suppressors as they create a lot of back pressure.
They have created an extremely high-quality muzzle adapter for the family of M1A rifles.
Once installed and aligned, a set screw positively retains the adapter.
The Delta P Design muzzle adaptor allows you to thread on an appropriately sized suppressor.
They are made in the USA from hardened billet material and are the real deal in my opinion.
For this task, I went with the Schuster Manufacturing SOCOM adjustable M1A Gas System.
This is essential for suppressing the M1A.
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.
For the suppressor, I chose the Rex Silentium MG10.
The MG10 boasts a hardness of 45-47Rc and tensile strength of 190,000 psi.
Its safe to say this suppressor is well up to the task.
The adjustable gas system from Schuster Manufacturing is another key to reliable suppressor operation on your M1A.
One important thing to note when suppressing any firearm is that its essential to check the bore alignment.
To check bore alignment, you need a special rod designed for the specific caliber of that firearm.
In our case, we used a Geissele 308 suppressor alignment gage.
With a suppressor mounted, the M1A SOCOM 16 remains a reasonably sized rifle for self-defense and other uses.
In Practice
Now, onto the testing.
The first few shots revealed that the gas was set too low.
It really was quite simple putting everything together and getting it to run smoothly and reliably.
If you have an optic mount that goes over the top of the chamber, that should help.
Conclusion
Personally, I love to suppress as many of my firearms as I can.
Its just so much more pleasant and fun to shoot.
