IPSC_RUS Posted November 26, 2011 Share Posted November 26, 2011 (edited) Hello, couple years ago friend of mine purchased Bushmaster AR-15 with 20 inch barrel and highly effective muzzlebrake. Made of ss with pretty ordinary design, but rifle control is nearly perfect. At least more effective, than with Mikulek or SJC. Any thoughts, who is the manufacturer? pics: Edited November 26, 2011 by IPSC_RUS Link to comment Share on other sites More sharing options...
gerritm Posted November 26, 2011 Share Posted November 26, 2011 Not an expert , but it looks a lot like my Miculek comp on my DPMS only polished SS. Link to comment Share on other sites More sharing options...

sbpt1911 Posted November 27, 2011 Share Posted November 27, 2011 (edited) Kinda like a stainless Miculek, just a little different , all the ports look to same size on your muzzle brake. Edited November 27, 2011 by sbpt1911 Link to comment Share on other sites More sharing options...
springy Posted November 27, 2011 Share Posted November 27, 2011 Try Holland Quick Discharge - It's one of the "older" models. I don't know much about it, my Grandpa said it was a goodun. Looks like someone polished yours. http://www.midwayusa.com/product/109958/hollands-quick-discharge-muzzle-brake-3-4-28-thread-stainless-steel Link to comment Share on other sites More sharing options...

IPSC_RUS Posted November 27, 2011 Author Share Posted November 27, 2011 Nope I have a Miculek in use, this one is designed more carefully, with math and engineering in mind. Inside diameter of the gas chamber with the side ports is smaller than Miculek. Side ports are different. I'll try to get additional pics on weekend.

ac4wordplay Posted November 27, 2011 Share Posted November 27, 2011 ... I have a Miculek in use, this one is designed more carefully, with math and engineering in mind. ... The Miculek was designed with neither math nor engineering in mind? How do you figure that? (I'm not a mathematician, engineer, or machinist, so maybe it's not obvious to me.)

The Miculek was designed with neither math nor engineering in mind? How do you figure that? (I'm not a mathematician, engineer, or machinist, so maybe it's not obvious to me.) I'am not saying anything bad about mikulek. It's "best for thr buck" product on the market. But I've tested various JP,SJC,Arredondo,Mikulek etc. The one on photos is holding a first place, eliminating recoil and what's most important - eliminaiting barrel movement. imho That's why I'am trying to understand who made it. The trouble is - most of my shooting goes with Barnaul ammo. Cheap ammo,hornady bullet. PF is a bit low, so muzzlebrake design does play a role.

usp45ss Posted November 27, 2011 Share Posted November 27, 2011 May be an older PRI. Looks pretty similar. Newer ones have ports on top as well. Link to comment Share on other sites More sharing options...

Guess I'll have to find 3D scaner and 3 axis machining center - it'll be a lot easier =) Link to comment Share on other sites More sharing options...
rep70 Posted December 8, 2011 Share Posted December 8, 2011 I would take a photo from the front at an angle it might give people a better look at the ports. Link to comment Share on other sites More sharing options...
