I recently bought an Olympic Arms K3B w/ 16" HBAR barrel. It seems to recoil much more than some of the other full size AR's I've shot. When target shooting on a bench, it really wants to jump after a shot, and I have to take extra time to reposition the rifle for the following shot.

Besides a muzzle brake, what other options are there for reducing the felt recoil of my AR? Also, will a muzzle brake really make much difference? What muzzle brake is the most effective? What about noise......will it direct a bunch of the muzzle blast back towards the shooter?

Oh you are going to get flamed on this one. Seriously thoegh thier is a company that makes an AK-74 brake for ARs. That brake is pretty much the best modern brake thier is on any AW.

Is there anything you can do with the buffer in a carbine stocked rifle?

You can use the heavier H2 buffer. JP Enterprises makes the most effective breaks. I hear they take out all felt recoil; never used one myself, though.

I think you can replace the gas tube with one that has a coil in it making it longer, this is suppose to smooth out cycling and reduce felt recoil. Check Brownells

Carbine length ARs are going to be a bit snappier in the felt recoil department than a full length AR and a heavier buffer will remedy this. Honestly I don't think it's a problem at all but to each their own.

ETA spelling

You might want to check out the EE for the rate reducing buffers by MGI and Enidine. Lots of good info. Also, from my own experience, a heavier bolt carrier (m16), a Wolff extra power recoil spring, and an PRI CQB brake have made a big difference in the extraction (read: better) and recoil (less) on the AR's I've installed them on. YMMV, good luck

I have the ak-74 brake on an a-2 and it is quite effective in reducing recoil, and brings subsequent shots to the exact same spot.

Just shoot it.

a couple ounces on a carrier is not going to make a big difference in precived felt recoil. A JP brake will work. Your money would be better spent on a JP type brake than a "H" buffer.

Make the rifle heavier. That will decrease felt recoil. Heavier up front (like a heavy rail tube) will reduce muzzle rise.

I'm not sure which to use for an AR specifically but a decently designed muzzle brake will definately work to reduce recoil.

I've got a brake on my FAL and it reduced the recoil noticably. However, it's *very* loud if you are standing off to one side when it fires and you can feel a huge pressure wave hit you. None of that's noticable to the shooter though.

Install a MGI recoil reducing buffer & feel a great deal of the recoil go away.
Link Posted: 9/17/2005 1:09:19 PM EDT
I also have an Oly Carbine Stocked 20" HBAR.

Here's what I did without using a muzzle brake. Shift your shoulder up on the stock so it is inline with the action. This way there will not be a rise of the barrel, but a straight backwards thrust. Helped quite a bit.

I tried using an M4 buttpad with it, but the way it's shaped tends to position the shoulder lower on the stock.

I also inserted an MGI buffer + 2x spring. While it's the same overall recoil, the "sharp" of the buffer hitting the back of the tube is greatly reduced. This results in a recoil that is more of a single-stage controllable affair. Plus it weighs over 7oz (just above H2 buffer weight)

Using this method, I've been able to pull off 20 shots groups under 3 MOA at 2 shots per second. This is keeping in mind I'm normally a 1.5MOA at best kind of guy (working on it).

Bottom line is, that with carbines, you have higher gas pressure, plus a shorter buffer tube. It WILL kick harder.

You can get a muzzle brake on the end, but be prepared for the substantial noise increase.

Get a 9MM buffer: www.rockriverarms.com/item-detail.cfm?ID=9MM0107&storeid=1&image=9part3.gif
that takes out alot of felt recoil.

Also either the AK style brake or the Y-comp break are good, which are both sold from Bushmaster. I find that the full size Y-comp works slightly better than the AK Brake, but is slightly longer. Of the two mentioned the AK Brake seems to be the loudest.

I use two MGI products: rate/recoil reducing buffer and adjustable gas tube.

If you think the recoil is bad on any 5.56mm AR you need to run, not walk to the gym.

Maybe he should walk . . . . . might put on a few pounds.

I dropped in a Speedlock Chrome Silicone Spring in my 16" RRA and it was like shooting in slow motion, I really couldn't believe it. Follow up shots were a snap, really no loss of my sight picture in between shots all were still in my Eotechs window. I never felt recoil was bad to begin with but now its more noticable because I dont notice it. All the above is your call ...
Link Posted: 9/17/2005 4:30:07 PM EDT
Make it heavier!! Get an A2 buttstock, fill it with one of the lead weights or add shot to fill it up. This adds a lot of weight, fill the pistol grip with lead, add one of the plugs . Anything you can do to add weight. Mine is EXTREMELY heavy for an AR and I can watch impact through scope and recoil is VERY light. I also have a 24 inch bull barrel and a solid aluminum accuracy rest that weighs about a pound on the botton of the float tube. If you have a carbine, they are not really made for bench shooting

Anyone have a link that shows how much velocity you lose when using various brakes?

Why would you lose velocity?

The brake is operating after the bullet leaves the bore.

I assume your talking about muzzle flip and not recoil. For muzzle flip, the brake on my Colt 6400 is the best. I forgot who makes it but you can find one for a threaded muzzle.
Link Posted: 9/17/2005 6:33:38 PM EDT
The Y-Comp brake (Available from Bushmaster) is VERY effective in reducing both felt recoil and muzzle rise. It feels like your shooting a 22 rimfire.
BUT the noise behind the gun will remind you if your earplugs are in tight, and will make poeple next to you at the range move away.

On the AK74 brakes you guys are talking about...do these have the thin zig-zag cut outs in the front corners? This is what seperates a true AK74 brake from cheap copies.
Link Posted: 9/18/2005 9:09:33 PM EDT
Depending on how much you want to spend, JP Enterprises has a lot of competition (vs tactical) parts that really make it feel like you're shooting a .22LR rifle. Low mass carriers and hammers, trigger packs, brakes, etc. Expensive stuff, but works. But then your rifle is not as reliable, so don't bet your life on it as a defensive/fighting gun.

Got one on a 16" medium contour bbl w/ midlength gas tube. Also have one on my 6.8 upper.

Shooter's next to me would give me dirty looks. Now I pick a station away from all the other shooters and warn anyone who considers shooting next to me that things can get pretty loud.

adjustable gas block,
heavier front end,
custom muzzle break.

My AR-15 has zero vertical movement when firing, and very little felt recoil in the shoulder. My 11 year old fired it at the range recently after firing the AR-7 22 and had no consideration of any difference between the two. My goal is to take a MPEG of it the next time at the range. Gotta get more memory for the digital camera.
