    C8FTHB: This is what most of the CF has right now. Standard old CAR grips with heatshields and uses the TRIAD rails to add accessories. Sling-loop on the left side of the lower-receiver's backplate. Black grips, flat-top receiver, no rubber pad on the old 4-position stock. We don't have that A1-style detachable carrying handle in the CF, we either put an Elcan C79/C79A2 (green), an Eotech or a BUIS on it. I have a picture of a C8FTHB with an Eotech and the new folding vertical grip that I had to install on every damn C7A2 and some C8FTHBs in the batallion on it, I'll post it later when I get home.

    C8A3: Most recent version, this will be the new CF carbine (we already started receiving them, replacing C8FTHBs). Same as an FTHB except it has green grips, comes with an Elcan C79A2 and basically comes with some of the features that the C7A2 got over the C7A1: ambidextrous fire-selector and magazine release, the longer and ambidextrous charging-handle latch (that gets caught on your gear and bends or breaks the charging-handle), the rubber pad on the stock...
    That information from Crosshair would be good to put in the article with some wording changes

    Also you could find information through these pages

    My C8A2 barrel seem to be 14.5inch in length....
    Speaking of the tri-rail that attaches to the barrel, I read in a Small Arms Review article saying that mounting too many things on there (PEQ, flashlight, etc) actually torqued the entire barrel assembly downwards from the wright, resulting in the cracking the bolt carrier after long use from the misalignment.

    The diemaco barrel does not make one bit of difference as far as being less ****e to overheating. cold hammer forged barrels are just more accurate since the chamber and the rifling are pound into shape with a one piece mandel, where the standard M4 barrel has the chamber and rifling cut separately, and the hammer forged barrels are more durable in theroy.

    The added weight does make for some POI shift and also lost of zero when the barrel start to heat up, all the weight can add to the stress of the barrel. as ar as misaligning the bolt to extension, i have only heard RAS user pulling down on the handguard with the VFGand the bolt start to shear with long sustained full auto fire.

    i would crossjump to a question if you dont mind?

    seeing that the brits got a new profile on their SFW barrels, i wondered if the new C8FTHBA3īs /C8A3 also would feature that.

    on the newer british L119A(no-idea-what-number) the middle ring on the reinforced endpiece of the barrel, has been removed as the guys use the L17A1 launcher instead of the m203 where the ring was necessary to mount the m203.
    do the new C8FTHBA3/C8A3īs also have the new profile, or would they keep the old? not sure what grenade launching platform the canuks use :/

    The CF use the M203. However, the mount is different, it is designed by Diemaco (now Colt Canada) and it makes the GL sit lower than the US mount.

    My current issued C8A2 has an RAS and an Eotech (with a 4x Magnifier) and a flip up BUIS (all added by myself). I'll post a pic or two in a few days.

    I use a C7A2/M203 with EO tech over here the reason there is a spacer between the 203 and the rifle is so you can still mount a bayonet stupid idea i think.

    Now that Diemaco has been taken over by Colt, is there still a difference in newly produced weapons?
