I'm going to try a Canadian clone build. Can someone tell me the difference between the c7 and c7a1? Thanks. |

Might find something useful here. C7 FAMILY OF COMBAT WEAPONS https://www.coltcanada.com/news-media/ |

C7A1 is the one I needed up with after trying all of the other types. Not a 100% correct but exactly the way I like it. Attached File |

I prefer the pencil with a RAS to offset the weight. Issued rifles use the A2 government profile. Let me know if you need close ups of anything. It’s a real Elcan bought it new in the late 90’s / early 2000. Love the scope. There are air soft replicas that are pretty close, but super short eye relief and a the mount wiggles, but looks 90% correct. Oh and the magazine is a maple leaf 🍁 marked Themold, though I think that CF have moved on from these. |

There used to be quite a dedicated cadre of Canadian clones here. |

That’s sobering, I still think the C7A1 is somewhat relevant, I remember when they came out and thought they looked so futuristic, and here is one in a museum!! |

Do you know if KAC made the locking bottom rail for Canadian's rifle M5 RAS like they did with the M4 RAS? |

Don’t know off hand, but mine has the SAS style locking bottom rail. I would imagine the CF and SAS followed each other laterally in kit and upgrades as they were both commonwealth / dominion forces with Diemaco rifle fleets. Not sure if the M5 was officially adopted like the M4, but for sure in use with individual upgrades. Would wager a nice lunch the C8 CQB uses the SAS RAS :) |

C7A2 added the collapsible stock. I'm sure there's more to it but I think thats the gist. That’s basically it. What people refer to as the C7A1 was a flattop Weaver rail as it predates the 1913 spec. Rail was the proper height so that an F marked FSB was not required. Short and long (spacer) stocks were available to those that needed them for proper length of pull. Triad mount came out sometime in the early 2000s. I definitely had one on my first deployment to Afghanistan in 2003. It was still called and marked C7 as the only new part was the upper. A mix of large and small forward assists. C7A2 came out in 2004 and was when the ambi mag release was adopted along with ambi selectors, although they didn’t have enough parts when they were initially upgraded. Stock colour was changed to Canadian Average Green at that time as well. Buttstock is a pebble texture but looks like the old Colt carbine stock. There are some smooth N1 marked buttstocks that are a darker green and I assume they were made by Colt. Peel washer on the initial conversions since it was the same barrel. What else? They came with the old style castle nut, I’m not sure if new factory ones use castle nuts or not. Four position receiver extension. All of them were marked C7 since the A2 upgrade reused the original parts. An A2 stamp was added beside C7 during the conversion and looks silver since it went through the anodizing. New ones are marked C7A2 from the factory. |

The Cdn government has ruined the hobby for me by banning the AR-15 up here in 2020. H2 buffer for the C7A2 and we still use rifle ramps in all of our rifles, including the C8A3. We are also still using the old black “tilting” follower in our D&H black Teflon aluminium magazines. I believe we switched to aluminium in the mid 90s due to cracking feed lips in the Thermold magazines. That would mean that Thermold is the only correct magazine for a C7. C7A1 used both during their service life, same for the C8 since we didn’t change them until 2003. In Afghanistan in 2003 we also had some some new C8s show up mid way through the tour that had a flattop weaver rail upper and the old 14.5” skinny barrel unique to the C8 with .750 FSB. They came with the EoTech 552 and I believe they had four position receiver extensions with N1 stock. I never came across them again and I assume they were procured solely for operations in Afghanistan. |

The PPCLI did purchase some for one of their deployments to Afghanistan but it would have been an off the shelf purchase and not an issued item. It was JTF 2 that used the RAS on their C8s with Cdn spec bottom rail. Us peons in the green army have only ever adopted the Triad rail. |

There are quite a few for sale right now. |

Thermold magazines were removed from the system in the mid 90s. Legend has it that the Cdn Thermolds suffered from fragile feed lips as someone involved in the procurement changed the spec of the composite. I hear that regular Thermolds aren’t nearly as fragile, but this is purely anecdotal. D&H black Teflon mags have been used since the mid 90s, complete with black “titling” follower. I keep meaning to take photos for you guys, but I’m a pretty good procrastinator  . Unmarked floor plates, just D&H Cage code Q4TQ4 stamped on the magazine body and I believe some have export only stamps depending on when they were purchased.

Considering how many photos of the C7s have them youd think it would have been more recent. |

I also was originally looking at getting a Canadian rear sight but cant justify the price. I think im gunna get a DD A1 rear and call it good. Fits the bill and is squint your eyes close enough. |

Regular force likely got theirs much sooner. I believe that Diemaco continued to use Thermolds in a lot of their promotional handouts for years after the forces no longer used them. |

I associate the C7 with the Thermold Mags so much I think they look strange without them. Wonder Diemaco kept using them? |

Wonder Diemaco kept using them? This is purely speculative, but they may have been left with a bunch after the Forces stopped buying them. They may have continued marketing in the hopes someone would buy them. It also seems to be pretty standard for firearm companies to not update photos and specs when they make changes, sometimes for years, don’t ask me why.  |

It sure does. It was either In Tarinkot or shawalikot in RC south. I'm guessing it found it's was to AFG with some of the first Canadian forces, unsure when that might have been, and was stored in a arms room at the little fob we were at for a number of years. |

It’s unlikely. First deployment was in ‘02 with the PPCLI, long after they’d all been replaced with aluminum. Apparently aluminum magazines have been made in Canada since 2010. I had no idea and only learned this today. I’ve only ever seen D&H Cage codes on our mags so I’ll have to take a closer look when I get a chance. |
