When the barrel length is given, is this dimension with, or without the flash suppressor (muzzle device) ? For example, I believe the military M4 uses a 14.5" barrel. Is this the length of the actual barrel, or is this the length including the flash suppressor ? What about with civilian uppers ? What is the standard (with or without the muzzle device)? |
| From what I've seen, if the total length includes the muzzle device it will usually be specified that way in the product literature; for example if the barrel is 14.5" and a muzzle device has been permanently attached to get it to legal (over class 3 ) length they'll say so in the product brochure - that's how I've usually seen the makers specify in their ads...now if it's a barrel with no muzzle device than obviously the overall length will be all barrel... |

I know in certain instances it is clearly stated. I own two such uppers. My Bushmaster M4 clone has a 14.5" barrel with a l o n g muzzle brake on it to bring it up to 16". I also have a couple of those 11.5" uppers with a permenant flash suppressor that brings the length up to 16". However, I how does my Bushmaster M4 look alike upper really compare to the real thing in terms of barrel length ? Are they both the same length barrel and mine has a longer muzzle brake to bring it into complience with the NFA ? Or is the military M4 barrel actually shorter than 14.5" and the flash suppressor brings it up to 14.5" ? |
