9/16x24 Lightest Brake? - pontoon - 04-24-2016
I'm looking for the lightest possible brake in 9/16x24 for 6.5 diameter bullets. My barrel has an outer width of .74" I believe. Titanium would be ideal, but stainless is OK. I thought the Grendel kick wasn't too bad, but I have a decent bruise after only 25 shots the other day. So I'm hoping this will mitigate the problem. It probably wouldn't be bad for most people, but I was injured in part of my shoulder, so I think it might be related. Also my stock has no padding on the butt of the rifle.

The Precision Firearms LMD is comes in at 2.9 ounces (I weighed it). I haven't installed it yet, but it placed third in a pretty comprehensive muzzle brake test.

Pontoon,
I have never felt any recoil I would consider unpleasant from either of my Grendels. One does have a brake, but the lighter, smaller one does not. I've put up to 100 rounds at a sitting through it and have felt absolutely no discomfort. Additionally, I've repeated this same scenario with a bolt action .308 with similar results and lack of discomfort, even though it does recoil significantly more.
To my point ... Are you certain your shooting posture and presentation are not the problem? Even the "lowly" 5.56 can eventually cause minor bruising if the butt is not held firmly into the shoulder. If you want to go with a brake, then by all means, do so. I am questioning, however, whether or not you may would be masking an underlying problem with your technique. If you are allowing the rifle to travel any distance to your shoulder, then consistent shot placement will be difficult to achieve, brake or no brake.
Or, it could be nothing. My bride has a folic acid deficiency (iron poor blood, as the old commercial used to say), and she bruises quite easily. A pad would be a consideration, under such conditions.

NugginFutz, the ergonomics of the gun aren't as good as my hunting rifle, and I can't get the butt to sit as low as I like with my 270 win (which kicks hard as hell because it's 5.5 lbs). The grendel build only weighs 5 pounds and has no rubber or foam padding. I also only weigh 130 lbs with low body fat, so there isn't as much cushion as I'd like. But mainly the gun is sitting in the wrong spot. I'm not putting it on the clavicle, instead right in the crook of my arm. The top of the butt hits hard on a spot of the shoulder where there is especially little padding before bone is felt (below the clavicle). To make matters worse, I tore something in that shoulder a few years ago and it didn't heal right, so the bruising could be partially due to that. I'm thinking maybe if I get a scope mount that extends even further, I might be able to get into a better shooting position.

Sorry to hear about the injury, Pontoon. As I've been telling a co-worker with similar issues - "Get thee to ye olde physician. It shall not heal of its own accord!"
As a hunting/target rifle, I understand you're looking to keep weight down. There are a couple of places you may not want to go too light, though. Buffer is one of them. A buffer that is too light will allow the BCG to cycle too fast. This, in turn, will result in both real and perceived recoil. I'd consider going back to a standard buffer to tame the cyclic rate. I would also consider going with a different butt stock with and integrated rubber butt pad. I know you originally were considering the A2 & plastic pad. If this is still the case, and you don't wish to change it out, I'd consider adding a slip-on rubber pad like 762n40 suggested to improve your comfort.
Good luck.
P.S. If I weighed as little as you, I'd carry all the spare ammo I could in my pockets, while hunting, just in case the wind came up.

I was in your boat, only for a flash hider. I also understand shoulder issues, I'm recovering from an almost 360 degree labrum tear with 6 anchors. It's why lightweight parts are so important to me now.
Get an adapter from here: http://www.brownells.com/rifle-parts/muzzle-devices/thread-adapters/m4-muzzle-thread-adapter-prod54364.aspx, it's super light.
Then get a brake from here: http://2a-arms.com/collections/muzzle-devices/products/copy-of-t3-titanium-compensator-1 Or here: http://www.vsevenweaponsystems.com/collections/muzzle-devices
I got my flash hider from here if you are interested: http://www.vsevenweaponsystems.com/collections/muzzle-devices/products/v-seven-ti-extended-a2-style-compensator-7-62-6-8

pontoon, WCI the company that makes one of the brakes on AA's website, used to make that same brake in titanium. People on here before the website crash used to rave about how well those brakes work. You might want to contact them( or contact AA on how to reach WCI) and see if they still make the Ti version.
Good luck.

Brakes/flash hiders are easy. Pick what you want in 1/2-28. The 9/16-24 thread is set so that cleaning out the 1/2-28 provides the perfect bore size to cut the new thread. Then check the exit hole diameter, adjust as required and you are done.
Light weight barrels allow enough shoulder so the crush washer sits square and does not cant the muzzle device and you do not end up with what looks like a 50 BMG muzzle attachment on a lightweight grendel.

Do not want to hijack a thread and did not want to start another one. A little help PLEASE!!!!!!!!!!!!!!!!! The other day I was looking around and came across a line that stated (something like this) "XYZ crush washers are the best because they are thin and crush easy" Of course I did not write it down because I thought I could remember the name, now I can not remember the name and can not find where it was no matter what I type in. Can someone point it out if they come across it again. Thanks in advance BANG BANG!!

Thank you
9/16x24 Lightest Brake? - leopard6.5 - 04-28-2016
Hi Slappy, you might look at Bill A.'s recent posts because I seem to remember him saying something like that in one of his recent posts.
You might even call him or email him if you can't find it just to get his opinion. He's always been very reachable for me.
Hopefully this helps and good luck.

Not trying to hijack, but what is the ~ recoil of the 6.5G compared to LC 5.56 55gr "NATO" (I know the 55gr is not NATO but just using it as an example). Assume a 16" mid-length, piston based firearm @7# loaded w/ A2 FH.
For the 6.5G, please assume 16", rifle length, 7# loaded shooting off-the-shelf Hornady ~120gr Match Ammo.
Another injured shooter
Thanks,
Bob

Somewhere between a 5.56 and 7.62mm. Like a 5.56 on steroids. Shooter-friendly without a brake and because of that the benefits of a brake are more about enjoying your shooting and maybe even what the gun looks like, than necessary.
