If I were to buy a post ban 14.5 M4 upper and have this pinned and welded to it would it be considered the legal 16 inches? I have one on my M15A2 and it is 1 3/4" [img]http://www.wilsoncombat.com/images/shops/city/products/TR-MB.jpg[/img] |

Quoted: Not a dumb question, you are right. I was talking about the pic only. If the brake is long enough to bring the overall length up to or over 16", he's OK. Thank you. I thought something was weird about that. I measured the Wilson brake that I have on my M15 and found it to be 1.75". I appreciate your patience. |

[egg on face]REALLY?[/egg on face] If that's right, then I was wrong all around and apologize. I had a Wilson brake on a post-ban several years ago and could have sworn it's overall length was less than 1.5". Could have been a different brake? Or, my measuring skills suck. Thanx for the correction. |

And yes, you do lose length when it's screwed on, since the threads overlap the barrel by about 3/4". A 1 3/4" brake, threaded on to a 16" barrel, comes up about 15.5 to 15.6 inches overall. That's why Kurt and other make "long" brakes and fake suppressors, to bring a 14.5" barrel out to 16" when permanently installed. You basically need a 2 1/4" long brake/muzzle device to bring a 14.5" threaded barrel out to a legal 16" length when permanently installed. |
