Default M1A Socom sans muzzle brake?

Hi all, I've got a M1A 16" with the very effective but loud-as-heck muzzle brake on it. After having many folks next to me at the range mention that it sends the concussion right at them, I'm wondering just how much utility it adds to my ability to control it? I'd rather quiet it down a bit, not just for politeness (a polite 16" .308? Now that's a joke!) but because I've been thinking of loading it with 110gr TAP for home defense and even a few decibels lower would be nice, though I intend to keep electronic hearing protection by the rifle. What're your thoughts on this? Good idea, or just another "head shaker"?

Thanks.

Big gun for home defense. Remember, you own it 'till it stops. Try a hider from an early M1AA1 or M14 and see if it helps.

If you do put a flash hide on it, make sure you bullet button it.

Home defense? Really?

Why not an 88 Magnum? It shoots through schools.

I run SEI's M14 SOCOM 16/II kit on my CQB-16 EBR

This kit gives you 3 muzzle device options.




Mine utilizes Muzzle brake P/N 1005-SS and it accepts my Wind Talker sound suppressor.

Consider another option for home defense...please.
For your familys sake and your neighbors.

It would be nice if civilians could purchase 7.62mm NATO/.308 Limited Penetration ammunition

IMO, a relatively long firearm chambered in 7.62x51/.308 isn't the best choice for HD.

A lot of folks can't control that rifle without the brake for follow up shots. Plus you may burn your house down from the flames coming out the barrel.

Home defense rounds really shouldnt have enough power to penetrate through walls, wouldnt want to hurt an innocent while trying to defend. Just my thought on using a .308 for that purpose.

Kinda reminds me of the guy in Lock Stock and Two Smoking Barrels when he puts on his ear protection to shoot off his Bren Gun.

OP, please consider a shotgun or handgun for HD if you live in a residential area! A .308 just isn't practical for that kind of situation. That is, unless your home invader is a zombie.

308 for HD? Really? Doesn't a 308 travel around 2500 fps?

The velocity isn't the biggest issue, it's a heavy bullet going fairly fast. That usually means over penetration in a HD setting.

You'll easily shoot through your walls, your neighbor's and possibly into the next house. Buy an inexpensive HD 12 gauge. There are tons of them out there.

OP here, thanks for your great advice guys. I asked because I wanted to justify the purchase of a long gun that better fit the role, but if the M1a could be used just as well, then I couldn't really justify the added gun. I really like where the consensus points me... to another long gun! I'll keep the M1A as a range toy only. Thanks again!

Don't get me wrong, it's a great rifle, but I would only use it for HD of I had a fairly isolated house, and was by myself. I would think long and hard before setting that bad boy off inside my house, you would be blinded by the fireball from the first shot and deaf from the muzzle blast. It is better than having no gun in a break in situation, but there are way better tools for the job out there.

HD? Better off with a .223 carbine.

Umm most of you folks do realize that a 9mm or 45ACP coming out of a 16" barrel will go through most home walls...just saying!

Aren't there Glaser rounds available for this? I would want to test them for penetration but it's an idea.

FantasticPlastic, sorry for the mini hijack of your thread...

Thanks!

I had a local shop (Accurate Ordnance) do the work.

I need to take a round file to the bottom of the hole and open it up a little more.

I'll post detailed pictures with my review in a new thread once I'm done.

Can you even take the brake off without loosing the front sight? I thought the front sight/muzzle brake/gas lock was all one piece.

Regarding using 110gr TAP rounds, make sure they actually cycle your rifle properly. I know TAP rounds don't work very well in my scout squad.

.45 out of a Glock 21 will go through multiple wood walls without an issue. Seen it happen. From the inside of a house through 3 layers of drywall, plywood sheering and siding, traveled 4 feet in air and then through a 1/2 wood fence and still kept going.

.308 would be insane.

I have a 16" converted Garand with a plain muzzle device and the fireball is pretty visible in bright daylight, not so much for the shooter, but anyone to one side or the other can't help but comment on it. Same for the report - it's not a report or flash I'd like to be exposed to indoors, hearing protection or no.

While most handgun and rifle rounds will penetrate more than one wall, a .308 round packs a lot more energy than any handgun or 5.56 round and probably will penetrate more walls/carry more energy after doing so. At one point, I tested rounds for my agency for use indoors, using multiple thicknesses of drywall with studs as test walls (duplicating the structure the weapons were to be deployed in) and found that only the lightest, highest velocity rounds failed to penetrate more than one wall (that one was a .38 +P+ 110 grain JHP load the agency had issued for use in revolvers). Every other handgun round tested, from 9MM on up, penetrated several walls... even the frangibles available at the time (Mag-Safe, for example). Even 5.56 penetrated a number of walls, eventually keyholing or fragmenting. All you can do is minimize overpenetration, you're unlikely to eliminate it.

Put all of this together and you've got a bit of a "head shaker"... in more ways than one!

Just fyi one of the things that made SKS & AK's popular with street gangs was the ability to shoot through cars and houses.
