    Re: BCM barrel length inconsistencies

    I permed a BCM Mod 1 this morning to my BCM BHF 14.5" barrel & while doing so, I measured everything. The barrel was 14.625" & my OAL is now 16.375". Personally, I wouldn't lose one wink of sleep over any of this as I'm not concerned that an extra 0.375" will snag on anything as I'm punching holes in targets.

    Wondering this as well. And how many times did you measure? You know those dowel rods have a mind of their own sometimes

    I could see a +/- .20, but a .50 (or .30 from an already 14.7) variance is wild if true. Not really seeing how that'd be possible to be honest, but I'm no manufacturer.

    Some people can spell, use punctuation and read a tape measure.

    It matters.

    Why do we need two threads on this non issue?
    Yes, I like pretty ponies.

    Oxford comma, use it.

    So the key takeaway from this thread is: when getting a 14.5" barrel to pin, buy the barrel first and measure it before buying an extra long muzzle device (e.g. a2x, BC 1.5, and BCM comp mod 1) regardless of barrel manufacturer. Sometimes you only need a regular length muzzle device.

    I love the Oxford Comma!!!!

    Yeah, for a guy (me) who prefers longer-than-A2 muzzle devices (SF MB and PWS FSC556), the difference between a 14.5" and a 14.7" is not worth worrying about. My wife's PSA CHF 14.7" FN-marked barrel (w/ perm'd A2) handles just about EXACTLY the same as my BCM 14.5" w/ perm'd FSC556.

    I've never had my muzzle get hung up on something (car door, web gear, duty belt, door frame, tree branch, etc.) and said, "MOTHER****ER! That last .2" just ****ED ME HARD!!! I WISH I HAD A REAL 14.5" BARREL!!!"

    In all seriousness, what happened if Colt's 16" barrels were actually 16.1"? Or if 20" barrels measured 20.2" (I've seen this multiple times on Colt 20" rifles)? Or if an 11.5" Noveske barrel was ACTUALLY 11.6"? *GASP*

    If exact barrel length bothers somebody, they shouldn't even waste their time measuring custom barrels from Bartlein and others. They cut each crown until it is perfect...this means that NO BARREL is exactly the same length......there will be variations. *SECOND GASP*

    This is normal, folks. There is some variation in machining processes. Don't lose your minds over it. Really.

    AND, in terms of tactics (i.e. in the REAL WORLD), .2" doesn't matter for JACK SHIT. Period.

    sorry, what you get from the hammer forge is a striaght product, accurrate barrel, that is manufactured on tooling as old as me. length will vary during crowning. best to measure and choose when it matters.

    I think it's hilarious that those assholes over on TOS will take a "stand on principle" when a barrel is not exactly 14.5", but they say "**** IT" when their bolt is made from 8620 steel (not Carpenter 158), MAYBE heat treated, and definitely not shot-peened.

    Cuz hypocrisy never happens over there. EVER.
