I am considering buying an M1A.  Originally, I wanted to buy either a Scout version (18" barrel) or a SOCOM 16 version (16" barrel).  Lately, I've heard from a lot of people that shorter barrelled version of M1A are extremely loud, to the point where you need more than normal earmuffs, or you hurt your ears.

 

If there is such a difference in noise levels, then I'll buy a regular length version.

 

Has anyone had a chance to compare the noise levels?

 

Thanks.

Ilya

The SOCOM is louder but its due to the compensator on the end of the barrel. I'm not a big fan of compensators. They direct the noise back at the shooter and generally increase the muzzle flash. Replace it with a Phantom or a Vortex flash suppressor and you will be much happier. The one SOCOM I shot had a vortex on it and wasnt any louder than a standard M1A. Personally I prefer the Phantom 5c made by YHM over the Vortex but they are both excellent flsah suppressors.

Thanks for the help.  

I know that a shorter barrel can make a gun noticeably louder, although that is cartridge and ammunition dependent. 

I do not know enough about different compensator designs, but I'll look into it.  I've always avoided compensators due the noise level, but M1A is not available without one.

Its been a while since I've had a M1A in but if memory serves me correctly they are not permenantly attached. Yankee Hill Manufacturing sells the Phantom flash suppressor in 7.62 (.308). Just unscrew the factory one and put the new one on.

It would be great if I could do that.  Unfortunately in the Fascist/Communist Republic of Kalifornia flash suppressors are illegal.  Springfield ships California legal M1A with a different muzzle break which might actually be permanently attached (I need to check on this).

Thanks for the advise though.  I might end up moving to a different state in a few years, and I am already keeping a list of all the stuff I'll be able to get then!

"which M1a"

 

ALL OF THEM   -  JUST BUY ONE OF EACH.

On the serious side it depends on what you intend to use the rifle for. I would not buy the short barrel rifles if there was any chance I would be shooting in long range matches. The standard version of this rifle can be about a 2MOA rifle and the match versions shoot much tighter groups in the area of 1/2 MOA. The short guns are designed for close quarters combat and are not as good at long distance as the full length rifles. The longer the barrel the higher the velocity. Buy the super match or the M21 if you might want a scope.  As for me I'm still hoping to find a magic lamp and get an M-25 for one of my three wishes.

A 308 in 16" is loud no matter what is on the end.(silencers excepted of course). Now for stuff that is better done in private. Math. 1 Pascal is 14.5 psi or 1 atmos.- exit pressure of a 20 in 308 is roughly 2000 psi or 137 atmos. At 16 inches the exit is about twice that or 275 atmos. This is a log gain of about 120 db over 110 db. While the 10 db gain is only 10 it is roughly the strength (lbs of force) of going from 0 db to 80 db. (log scale remember). I had a tanker Garand that was really, really loud. Too loud. Also several Match grade Springfield M1A and standard M1A . my advice- get an FN. Maybe no quieter but a better gun.

Can't get an FN until I move out of California, and that is not happening for a few more years.

Can't get an AR or an AK.  Already have a couple of SKSs and a Kel-tec SU-16.  Other semiautos available in California are Browning BAR, M1A and a stripper clip only FAL by DSA.

Thanks for the advice though.

We are in the process of building one our selves for T&E and R&D.  We sell hundreds of Super Sniper scopes to the military for their M14s.  The Navy EBR (Enhanced Battle Rifle) version uses an aluminum chassis stock system, which is what we are building ours off of.

 

 

 

I've been considering an M1A from Armscorp USA, Inc.. http://armscorpusa.com/ to put in our stock.
