Been lurking here for a few months now and have been soaking in all the info as a relatively new gun owner. I was at BA the other day and a few people were shooting some compensated AR's. However, I notice many of the off the rack AR's in the shops don't have compensators... would these be noticeably quieter from the shooter's standpoint. If so, is there any real benefit to adding in comp in a caliber that hardly has any recoil? Thanks in advance.

Comps are much much louder than a standard barrel. Some are twice as loud Like the AK style comps, Brutal..

 

In .223 it is hardly notice able as you already stated not much recoil.

 

It will help with fast follow up shots like when running a Ipsc of 3 gun course of fire.

 

Most want it on there .223 because it is tacticool looking and looks more like it should with a flash hider.

 

I have a Bennie Cooley comp which is great, And a Armalite comp which sucks.

Also a 16in Plain barrel Bushy that is just fine how it is,

 

My favorite for looks is the Noveski Pig.

As stated above, non compensated are not as loud but I'll add that the difference isn't as pronounced for the shooter. Compensated or not, while there is some difference for the shooter, there is a HUGE difference to the people nearby.

Yea, not to mention the blow back the people around you get on top of the more pronounced sound. If you're shooting outdoors or in another situation where there is no divider, the people to the left and right will catch a face full of stuff.

Along with the fact that brakes allow for easier follow up shots, it also helps protect the end of the barrel-- unlike crowned barrels (though a person should always still be careful).

 

If I lived in a free state, I'd probably go with a three prong/Blackout from AAC.

whats it matter how loud it is? if youre ever shooting any kind of gun without hearing protection, you deserve to get hearing damage in the first place. same thing goes for chainsaws.

 

i have shot my original bushmaster upper with the AK comp, then a plain barrel version the same day. there is a noticeable decrease in recoil and muzzle rise. but again, its not a 12ga slug you're shooting either way.

I do not care for comps on my Jersey compliant AR's because it makes replacring or changing the FSB a serious pain in the ass!

It sucks to be next to someone shooting an AR with a compensator. Last night my targets and gun sock kept getting blown off the ledge in my booth because my neighbor was shooting a comped AR. And there was a dividing wall between us, but his muzzle was a little forward of it. Oh yeah, and it was painfully loud even with headphones on.

I wonder how bad the blast will be from my comped 338LM :twisted:

:confusion-seeingstars:

You also can't enter any kind of NRA-sanctioned competition with a compensator on the barrel. I had to re-barrel my Colt HBAR for service rifle competition because of this. Also, at unsanctioned competitions, the guys to my sides were always waiting for me to finish before they would start, because the muzzle blast was so unpleasant.

Hehehehehehehehehe

 

Im in a quandry right now with the Tax refund coming in. JUMP on an NIB Remington 700 in 338Lapo for $1300.00 (with another $2500 needed to put a base optics, and basic load of Zero Ammo) or go cheaper for a 300Win Mag.... I REALLY want the Lapua though.. Decisions...Decisions....

Note: This is all NFA stuff.

 

First time I saw the FSC 556 was in early 2008. I just bought my first 11.5" upper and it was not cycling. I borrowed my good friend's 11.5" upper and noticed two things. It worked, and there was no recoil or muzzle rise. I thought to myself, "Self, that was strange." It had the FSC.

 

These are not the hottest comps, but I have them on all my FA uppers. I can't tell a difference in noise on the 20" bbls. I can tell the difference in controllability. But, on the 11.5", with 5.56 ammo, it aint just noise. It's blast. You feel like the fillings are going to pop out of your teeth. It's nice

OP,

The purpose of the compensator is to help deal with recoil. In a .223 AR, recoil is hardly an issue, so that leaves the almost sole purpose of the comp being an enhancement of the "kewl factor". If you want practicality, go with a plain muzzle. If you want "kewl", get a comp.

My AR has a 16" bull barrel (like .920 dia,) I was thinking of Magna-porting it.

About $100 total. Why don't more people do this? Your thoughts...

How much velocity loss is there since it's a short barrel to begin with? I think most folks put brakes on .223 ARs just for looks...there's really no need since the recoil is almost nothing to begin with. Porting doesn't really add to the look as much as a brake.

 

When I finally get around to building an AR this year, mine won't have a brake on it. Not that I think they're bad, just not my thing. Now if I could get a brake that reduces noise but doesn't rise to the level of a suppressor, that I could be interested in. Maybe I could get an accelerator that increases felt recoil but directs the noise and blast down range

Mark-- I don't think there would be any measureable velocity reduction from Magna porting. As far as reduction of muzzle jump it's a rifle intended for competition so any edge is welcomed.

 

If you want to shoot mine or work on a build, you're riight around the corner, let me know. Being the cheap bastard I am, I'd help you build the best quality rifle that could be built for the cheapest price.

Agreed that .223/5.56 hardly kicks. But for hammer drills and multiple engagements beyond that-- having a brake does have its uses. For range duty, I too would stick with a crowned barrel.

If you're venting pressure before the end of the barrel, there MUST be a velocity loss. Perhaps it's not much, but there must be something.

 

Looking here http://www.accuratereloading.com/223sb.html It appears that each inch of barrel results in 20 to 80FPS loss. Porting the barrel may not be a complete loss but you're losing full pressure about 1.5inches back from the crown. Suppose you're losing 30% of the pressure...that's going to be 9 to 36fps[(1.5 * (.3 * 20))] or [(1.5 * (.3 * 80)) . Ok, not much of a big deal. Shrug.

 

I'll keep you posted on my AR build. I'm thinking of getting that non pistol grip thing from the other thread and having the exposed buffer tube. Why not, at least it'll be different.

Because Magna-porting is just another version of a compensator and over the years I've learned to steel myself against the vicious recoil of .223 out of a gas operated gun. :mrgreen:

^^^This.

 

If you guys show up at a carbine class with nothing on the end of your barrel you will find out very quickly how much a comp of some sort matters - even the A2 flashider helps some.

 

You can use your rifle for whatever you want. But, generally speaking, these rifles are intended for fighting. Not deer hunting.

Agreed Mark- But any way you look at it the loss would probably be about what the standard deviation of the ammo is. I didn't look at your tables but tables I have looked at are very interesting. The greatest loss in velocity is when you remove length from an already short barrel.
