Well, I had a free afternoon so I decided to deplete my ammo stash. I have the Bushmaster X15M ES2 H Bar and I have to admit, I had no clue this thing would be this loud. Do you guys think its just this gun or do your ARs put of some decibels as well? I'd have to say it's louder than any SKS or AK47 I've shot. I'd say almost as loud as a snub .357 pistol. Over the course of about 100 rounds only one jam. I was happy to say the least. Both mags (1 polymer, 1 metal stamped Miltary/Police/Law Enforcement Use Only) that came with the gun worked well.
By the way, does anyone here have any experience with the rubber accu-wedge product? I purchased one from a local gunsmith. I hope to tighten the receivers up a bit. |

You are wearing ear protection when you shoot, right?
I do think my 16" ARs are generally a bit louder than my SKSs, especially the one with the muzzle brake. ETA - Barrel length is measured from the bolt face when closed to the end of the barrel itself or to the end of the muzzle device if it is permanently attached. |

The .223 is surprisingly louder than you would think looking the cartridge.
What length of barrel do you have? Do you have a A@ FH on it? I have a bushy w/ a 24" barrel on it and it pretty tolerable. My bushy 16" HBAR will definitely cause some ringing if your close by, but what a shooter! IMO the best thing you can do to the accuwedge is throw it away. A little movement between upper/lower is not such a bad thing. Too tight and things bind and not good. |

I am betting you have a muzzle brake on your AR my 20" Ars arent bad at all. My 20 inchers are brutal, but then again, I don't wear ear protection half the time. with no ear protection with a standard A2 flash hider. Mine arent bad at all. Now out a muzzle brake on there and you can blow out an ear drum. |

Please, please, please, always wear your ear protection. During training (Army) in the early 70s, we didn't wear plugs and now my ears ring all the time and the decreased hearing has affected my hunting abilitys, and a lot of other things. Hearing loss will wait around for a few years and then show up. Wear your ears, not being able to hear well stinks.
just my 2 cents, Eric |

. Over the course of about 100 rounds only one jam. Strawberry or Grape? I'd be upset if my AR had a malfunction every 100 rounds. What was the nature of the failure? By the way, does anyone here have any experience with the rubber accu-wedge product? I purchased one from a local gunsmith. I hope to tighten the receivers up a bit. Useless BTW the ONLY way you can measure barrel length is to close the bolt and drop a rod down the bore (so it sits against the bolt face). Mark the end of the barrel (if you have a permanently attached flash suppressor you can mark it at the end of that). Pull the rod and measure from the end of the rod to your mark. |

One more thing, without taking the handguard off, how do I measue the barrel length? Still not quite sure what I have here. With the bolt closed on an empty chamber, put in a long cleaning rod from the muzzle. Have a yardstick ready. Mark the end of the flash hider with your finger or use a marker. Take the rod out and measure it. There are many combinations, so let us know what you measure it at and we can probably say what you have. For example, 16 1/4" might be a 14.5" barrel (to the end of the threads) with a 2 .25" flash hider welded/pinned on. 17 1/2" would be a standard 16" barrel with an A2 flash hider screwed on. A standard A2 FH is about 1 1/4" from the end of the FH to the muzzle , so the 16" barrel in this case is actually 16.25". They do this on purpose so there's no question of legality. A standard 20" barrel with FH might come out about 21 1/4". That's about all we could tell by barrel measurement. Without a full series of pictures and every marking, we can't say whether the upper ass'y is Bushmaster or not or what contour the barrel might be (government profile or heavy-barrel).. |

Thanks for the feedback fellas. I'm positive the upper is a BM. My friend purchased the gun brand new, with a BM case and all. That being said, using the quick references you guys provided, its a 20" barrel. The barrel is marked 5.56 NATO 1:9 H BAR
As for the jam....when the gun didn't shoot I checked the chamber and the round had an about a 45 degree angled being pressed by the bolt and carrier. Of course the bolt didn't fully engage. When I pulled back to eject the round, instead of ejecting, it decided to go ahead and chamber the round that was jammed. So 1 over 100 is pretty bad huh. Now I think about it, I can not remember 1 jam in my stainless Mini 14 RR. So you guys think there's a problem here? |

Anyone have an idea about how many rounds of 5.56/.223 would be enough to cause permanent hearing damage? According to OSHA standards, any impulse noise with a sound pressure level of 140 dB or louder will cause permanent hearing damage. As an AR-15 measures anywhere from the low to mid 160's (dB), one shot without hearing protection can indeed cause permanent hearing loss. The extent of that loss will vary from individual to individual and will depend on the number of exposures. |
