For MR556 or MR223?
Then if you do not want to retread brake or barrel you need to use one with M15x1 tread. PWS makes special version for MR223 called FSC556HK. Also FSC91 fits MR223 but it is intended for 7.62mm. Arredondo makes their NxG brake/comp with M15x1, you just need to request this specifically (no option on webshop).mine is MR223
M15x1 denotes metric thread with nominal diameter of 15mm and thread pitch 1mm. When no remarks, right hand thread is assumed. M15x1 is standard HK thread used for rifles.thread M15x1 is same as 15X1 right hand thread which is the thread pitch?
To mount it you will need to have made collar that will cover recessed plain part of barrel after threads. You can make it out of original thread protector nut. Or you can go in "scrapyard challenge" way, like I did. I stacked 4 (four!) AR-10 crush washers (then I carefully checked if brake is concentric to the bore). Anyway you will need to figure out what you like best. If I would have some time, I would pay a visit to gunsmith and ask him to convert HK thread protector into counter-nut to mount brake.I went wirh ARREDONDO nXg Compensator
Less bang for whom? No muzzle brake is going to have a sound suppression effect, but different designs will change the direction of a the main waves of sound. Most good competiton style compensators are perceived to be louder to the shooter and others on the line, because they direct the muzzle blast (and with it, the pressure waves that create sound) sideways.Thnx for the reply, I am looking if there somethign universal, less bang
It's not that U.S. dealers dont want to ship it and get more business. It's that neither you nor they want to pay the thousands of dollars for an export license for what is roughly a $100 part. That's before you even get into Canadian import restrictions or requirements, which I don't know enough about to comment on.good info, for Canada side, seems like hard to find OEM parts and a lot of US dealers don't want to ship either I went wirh ARREDONDO nXg Compensator, I hope guys understood about thread Thnx Montrala
