[ARCHIVED THREAD] - BCM Rail....? (Page 1 of 19)
|
Quoted:
The rail is a magnesium alloy, and weighs 7.5oz (13" rail" My rifle with T1 LT mount, Troy BUIS's, Fury light and VTAC mount is 7lbs <a href="http://s1249.photobucket.com/user/EAG_TACTICAL/media/APD%20Pistol%20SH%20July2013/122_zps159a304d.jpg.html" target="_blank">http://i1249.photobucket.com/albums/hh515/EAG_TACTICAL/APD%20Pistol%20SH%20July2013/122_zps159a304d.jpg</a> It's a true survival rail!! You could always shave of a couple slivers to start a fire! 
That's seriously light! |

Need more info!! C'mon BCM, what lengths will be offered? Pricing, any kind of ETA? Hows the rail mount to the barrel nut? I've been waiting for the URX4 but this is drawing my attention! Looking for something longer than 13" my BCM BFH 16" barrel is lonely and NEEDS to be installed

Looking for something longer than 13" my BCM BFH 16" barrel is lonely and NEEDS to be installed Im sure they will give a proper announcement in due time. Patience my friend. Im in the process of building an 11.5". If they have a 10-10.75" version, I will be a happy camper. |

Quoted:
With it being magnesium, can it light a fire with it?
Kidding, but how's the durability of the magnesium alloy vs the 6061 rails that are pretty much the industry standard? they should be a little lighter and a little stronger there's a lot of interesting reading out there on Al alloys |

Quoted:
Do these rails get hot during high volume fire? Seems that very slim rails with no heat shield such as the troy alpha, daniel defense MFR, etc., get hot pretty quickly if you aren't shooting with gloves. Would like to know how this compares. I'd suspect it to behave like all other slim free float rails - wear gloves! |

well maybe BCM is working on a line of gloves then?  Right Here

nice wish they made em in size 14 -4XL though Quoted:
nice wish they made em in size 14 -4XL though Oh damn good luck finding gloves for those HUGE meat hooks

Pat, How are they finished? Probably some type of anodizing, or maybe a paint. Did some research on magnesium finishing, and MIL-M 3171 type IV anodizing seems to fit the bill: Type IV (Dow 9): A galvanic anodize treatment for magnesium. Produces a dark brown to black coating. Designed to give a protective film on alloys which do not react to Dow No. 7 treatment. Only fair corrosion resistance (less than 24 hours 20% salt spray resistance). Makes no dimensional change. Can be used as a paint base, and is suitable to all magnesium alloys. Used where optical properties (black/non-reflective) are required on close tolerance parts (camera parts, laser components, telescopes, etc.) Note: Precleaning and pickling may result in dimensional changes due to basis material loss. Who knows though, it could be painted with something like ionbond or cerakote. I can't say I know very much about finishing processes on all sorts of metals, either.
