Not worth the money? Very closely copied from Browning design? Useless piece of crap? The greatest invention since sliced bread? Doesn't work or does work?
I am not familiar with the Browning design from the past as some of the commenters from the video made reference to in the comments below the videos so maybe someone that has experience with their design or has used one can chime in.
I am not in the market for this so this is not about me getting opinions to buy one. Just curious what everyone thinks.
Correction: He is shooting an AR10 in 6.5 Creedmoor with factory ammo in the videos.
Anyway the brakes are threaded 5/8x24 and come in 6.5 and 30cal sizes (both sizes can be used on the 6.5 Grendel) and a 1/2x28 adapter can be used to mount this on a barrel with 1/2x28 threads. Also I don't know how good the brake is at reducing recoil.
Here is a pic of the brake: [ATTACH=CONFIG]17393[/ATTACH]
Here is where you can buy it from (they are backordered and will be offered in black at a later date):

Here is the video showing Eric shooting and adjusting the brake with his results:

Here is the video explaining the specs and so forth:

Looks cool and in theory makes since.
But on the other hand, I would rather just have the must effective brake and tune my handloads to the barrels wants.
If your a factory ammo only type shooter, it does make sense but then again you will have too retune it every time you change ammo I'm thinking.
