Well, not exactly: Hers is a C8A3, the Canadian version of the M4.
Two stories behind these two guns: My M4 started as what I hoped would only be a "bridge loan" purchase until a friend who was in a nasty divorce could buy back his bring-back parts and resume rebuilding his old Rockpile work gun. Sadly, the demos that followed him home were too much fight for him to win and he joined the Two Dozen A Day... after his kids declined to exercise the Right Of First Offer in the purchase agreement and told me "since you were looking for an M4 as a 'teaching gun', finish it for that role and use it to tell his story--it's what he would've wanted so a little bit of him can continue to serve." The upper is a Colt contract, shimmed just enough to make it Title I by John Thomas at Retro Arms Works. Even in-person you have to look REALLY close to see where Colt's steel stops and John's begins.
since my gal is Canadian, we decided it would be an appropriate touch to give her something rare by building her a C8 - when I was doing research, a bunch of guys on a Canadian gun-board hooked me up with some of their spare bringbacks in the same spirit to memorialize their fallen brothers with a "teaching gun" for my classes on Range Day. They jokingly call her gun "the unofficial Canadian Afghan War Memorial" after the Turd, may he soon be flushed, decided to bury the real one in a deep-top-secret part of a base where nobody will ever see it. (One ting not CF-spec is the Umbrella lower--that was a unique personal touch, C. is a huge Resident Evil fan to the point that she's said if she ever gets a crack at wooing Milla Jovovich my options are either learn to share or become The Next Ex.) The folks at Gunkote even put an expedite on developing an air-cure version of their Napa Green for the buttpads on this project.
We also have all the parts for M16A4 and C7A2 20" second uppers*... but with no accessible bench vise to torque flash hiders and PNW gunsmiths dropping like flies, I need to find someone who can teardown and reassemble the front ends and swap the triangle endcaps for rounds. (The 20" URG's were among Aero's last out the door before WA banned AR parts... but they can't legally exchange the URG's and won't do the work to swap the parts.)
*Assuming I can ever disinter the M5 RAS for the A4 from the mountain of boxes it's entombed under in my storage unit...
These two pics are from the day my former FFL outshopped the refinished green furniture and did the post-assembly "look over my shoulder" inspection--before Rumored Pederast Ferguson ran him out of the state, Dave was as much a teacher and mentor as a service contractor and dealer, one of many people in a variety of fields I've been blessed to have take me under their wings.
I also have the matching USMC Ontario OKC-3S bayonet, but at the prices for a Canadian spec Eickhorn B2005 I've told C. that's one part where she's gotta buy her own. (Besides, I was raised that gifting a knife wounds a relationship--when I found a screaming deal on SOG Cash Cards and snagged a spare for a buddy, he got it for a penny as a "pro forma.")
Just thought I'd share these. If anyone has questions, I'll try to answer as best I can. Bonus: who wants to take a stab at what this is?
