AAC Brakeout

[mildot]

Anyone have any idea when this will be available for sale?
Any dealers on the board going to carry some/ pre order?

[rob_s]

I hear that the version pictured is probably sometime next month, I'd guess closer to middle/end.

Check out this brake by Rainier Arms. http://www.rainierarms.com/?page=sho...roduct_id=1684

[ColdDeadHands]

supposedly soon! LOL that's all I can tell you.

I wonder how obnoxious it will be for the shooter?

[JRDavis89]

Well at least one version is out now.

I'd be interested how it compares to the PWS FSC556.

I'm planning on buying both, and the Rainier item linked to above.

while it will be totally unscientific and will not address rise or acceleration, I'm planning on making up a little rest/sled and measuring how far back the rifle moves in the sled with each of the three.

[ColdDeadHands]

Cool, can't wait to see the results. Maybe you could comment on muzzle rise from a non scientific standpoint.

[militarymoron]

i'm more interested in muzzle rise than recoil reduction (althought that's good to know, too).
maybe there's some way of supporting it that allows it to 'jump' at the muzzle, and the amount of jump indicated by how much it moves/displaces a marker? a regular v-rest at the front should work.

[rob_s]

Rise will be second, but will be a bit harder to measure. My hope is to work out a jig that works for both, with a way to lock it in either dimension to measure strictly that dimension. So a way to lock the gun down to measure straight back, and lock it fore/aft to measure straight rise. The range I use has concrete shooting benches permanently affixed to the ground on concrete piers so all I have to do is work out a way to clamp it to that and it should be solid.

The problem with climb is that if the rig is too heavy it won't climb at all. It needs to have a way to fix the stock to the rig, but pivot, and let the rest of the gun move freely in the vertical direction only. My intent is to modify a spare M4 stock so that the rifle can be bolted down at the toe.

i'd like to see these results. i have been thinking about both.

[Ratfink]

aww i just got a new upper with a blackout welded to it since its a 14.5 and then somthing like this comes out and that is pretty sweet looking i havent shot my new upper the lower is still being built it never fails whenever i get somthing cool somthing cooler comes out

[Robb Jensen]

I'm hoping to get mine in our first shipment from AAC that we ordered at SHOT this year.

I'm curious to see if this thing will offer any real flash suppression. Most of the "combination" devices I've seen aren't all that great in the flash suppression department.

[ClosetCaseNerd]

Hmmm........


Flash is a function of unburned powder combined with oxygen, and flash hiders function by accelerating the process (something to do with surface area of the tines of the FH) within the confines of the flash hider, shielding it from view. Or...uh...something like that

So...wouldn't the FSC556 work significantly better as the ports on the sides have tines? And it seems to me that they redirect the blast better as well...

Just thinking out loud here.

Ever tried an FSC556? Its no vortex but its also not a fireball throwing monster. Considering its a pretty damned good compensator i would say its actually a pretty amazing jack of all trades.

[crazymoose]

Have tried it. Seemed to me to suppress flash about like an A2, but pics I've seen in the dark make it actually look less effective.

I understand that a balance has to be struck between the ported gas coming out of the sides vs. the amount going out through the end and being affected by the tines. The more gas comes out the sides, the more effective the brake, but that also means less flash dissipation. As ClosetCaseNerd pointed out, even the side ports of the FSC have tines (although I don't know if they're functional or merely aesthetic). However, the Breakout appears to have pretty giant side ports, so I'm wondering how much unburned powder is actually going to make it through the tines on the end. I have no doubt that this thing will be quite an effective brake, but I'm dubious of its benefits as a FH. I hope my concerns are unfounded. AAC makes a hell of a product, and I wouldn't put it past them to pull this off.

My intent is to modify a spare M4 stock so that the rifle can be bolted down at the toe.

If the rifle pivots around the toe, say via a horizontal bolt through the quick release sleeve or a sling hole if present, and a video camera captures the rifle movement while it fires, with a ruler positioned vertically just back off the muzzle, max height reached by the barrel can be measured for each of the muzzle brakes/FH.
Looking forward to the results. Objective info is hard to come by; lots of subjective "feel like.." and BS ads.
Thanks in advance, Rob.

At least with the FSC556 and the AAC Brakeout, you are able to mount a supressor.
