Hi everybody, first time posting here but have been a lurker for a while. Sorry for all the text
I've really enjoyed reading the muzzle brake comparisons from TTAG and I recently realized I have a pretty nice sized collection of muzzle brakes here. I'd like to do my own test but I'm not really able to go out into the woods like Jeremy S does. I'll have to do mine outside or in an indoor range. I'd like to solicit some advice on the testing protocol. I have currently a cellphone attached to a MBUS knockoff that I attach to my handguard to take "GoPro-lite" videos. On it is an app that measures acceleration forces on the phone. I could use this to test the muzzle brakes, however the major negative is that it measures acceleration so we'll be able to tell how "sharp" or "snappy" the recoil is, but it'll be difficult to convert it into actual inches of rearward recoil. Also, it won't easily measure muzzle movement. Another option is to use slow motion video and hold the muzzle as steady as possible like what Vuurwapenblog did. It may be possible by putting a grid behind the muzzle as to give a frame of reference. Another option is to use a dslr camera with long exposure and a rail mounted laser to measure muzzle movement. These are the ideas I have so far. I would gladly welcome better and more feasible ideas. I currently don't have a good plan for measuring concussion/blast other than putting a piece of paper nearby and seeing how much it moves...or just going by "feel" which is highly unreliable for me to perform unless the difference is blast is that of a 3 port brake and a suppressor... FYI these are the muzzle devices I have currently MI Flash hider Battlecomp BCM Comp Mod 1 Griffin Armament Tactical Compensator SLR Synergy comp (Looks veeeery much like the griffin flash comp, lol) A linear compensator with thread ports a la Effin A comp (my own design) 2A T3 compensator I will probably obtain an A2 for baseline Thank you all in advance! |
| There was an article posted on this board a few years ago comparing comps & brakes and they used a fixed laser on the AR and a long exposure camera which basically 'painted' a pic of the total range of movement of the barrel when fired. Probably the best visual representation of muzzle jump although there's been a lot of new stuff out since that article. It's easier to measure the recoil force that the muzzle jump, but for me I'm more concerned with controlling muzzle jump. Never knew that a device could be so efficient that it actually forces the barrel down but that seems to be the case. |
