Something I mentioned in another thread drew a response that seemed to indicate it was worthy of follow-up, so I thought I'd run the idea up the flagpole and see if anybody saluted.
Component Mk 18 Mod 0 and CQBR Block I Mk 18 Mod 1 (and CQBR Block II?) Upper Receiver Flat-top Gas Block FSB Lo-Pro: Daniel Defense or Badger Ordnance Handguard varied, including:
M4 plastic (earliest models)
KAC M4 RAS
KAC RIS (SEAL preferred)
Daniel Defense RIS (Ext Carbine, FSB slot)
VLTOR CASV-EL (Navy EOD)
Daniel Defense RIS II Flash Suppressor/Brake KAC M4-QD KAC M4-QD
An alternate option might be to set up an M4 Carbine Wiki at someplace like Wikia, where anyone can directly add their own data to the relevant page.
As I noted in the opening quote, though I strive for professional-grade effort and skill in everything I do, I am not actively a firearms professional aside from two years of Executive Protection back in my college days so I cannot contribute from field experience, but what I do have to offer is skill and experience with data collection and assembly shaped by years of experience as a technically-oriented military historian and research contractor, and helping organize the data I can collect from trawling the Net and this community can contribute from experience as manufacturers, dealers, homebuilders and operators might be a chance for me to contribute something of value from my own different little angle. I can't do it all--I'm not sure with all the different variations on accessory outfitting alone no single person could!--but at least maybe I can get the party off to a solid start if this is something worth doing.
Anybody out there have thoughts on the value of such a project, or on refining my rough idea into an actionable plan?
