None of them, to my knowledge. Usually adding a MD to a 14.5 is barely enough most of the time, and is sometimes still too short depending on MD.
13.7...thats a stretch. Time for a stamp.

Yep.
Even a B.E. Meyers which is ~.25 longer that an SF is too short. |

The only md to bring a 13.7 to legal length is the Noveske KX3 and KX5.
Obviously not gonna work for what you need it for. Ditch that barrel for a 14.5. |

Mickdog is correct: you might as well have useable barrel working for you rather than useless muzzle device working against you...especially when the former is less expensive.

The Surefire Warcomp isn't too short if you use shims. ADCO Firearms pinned and welded one up for me to make 16".

Quote HistoryQuoted: Yep. Even a B.E. Meyers which is ~.25 longer that an SF is too short. I just measured my 13.7" barrel with a BE Meyers flash hider and a single crush washer. This combo makes it to 16" easily. |

16" - muzzle device length - shim/washer thickness + barrel threads length = minimum barrel length needed (of course, you should probably go over this a little bit)
FYI, A2 is 1.875" 3/4 prong flash hider is 2.670” muzzle brake is 2.660” WARCOMP is 2.720” closed tine flash hider is 2.330” I don't know the closed time WARCOMP length So for the WARCOMP: 16" - 2.72" - .05" + .63" = 13.86" So, if the 13.7" barrel actually measures 13.875", it would be long enough. |
