    MK 318 ammo Info 5.56

    KAC doesn't make the complete rifles (actually not even on the SR25 anymore, as it has been replaced by the RSASS), but what they do is make the rail systems, and EVERY variant of the M16/M4 that I have used that had an issued rail system had a KAC rail system. Colt made the majority of the...

    MK 318 ammo Info 5.56

    Yeah, I was just shocked- when I arrived at Basic, and they issued rifles on day 2, most of my platoon mates had Colt lowers, some had Olympic, I had an FNH.... I was of the impression prior to this that Colt and KAC were the ONLY companies that the US Army contracted with for M16/M4 weapon...

    MK 318 ammo Info 5.56

    Alright, I can't find any evidence of the 1/7 twist rate changing. DID find that the specific reason for changing to the 6 groove, right hand 1/7 was to accommodate the SS109 NATO cartridge, which was apparently heavier than the Stoner test ammo and the M193, and yawed too much at a distance, so...

    MK 318 ammo Info 5.56

    OK, found a TM dated 1998 that states that all 5 weapons systems in the M16 family have a 1/7 twist rate. Granted, they spell the word "riffling," but I'll try not to count that against whatever pentagon desk jockey typed it up. I'm gonna do further research to verify that it didn't change after...

    MK 318 ammo Info 5.56

    Know what I hate? Navy designations. Yours is a Mk18? Thought that was the 16" variant. Did I get it mixed with the Mk12 again? Yup. I did. My bad!!! Mk12 Mod 0 is what I meant. That is the 16" pseudo-DMR M4 produced by the fine folks at Crane. I was sooooo sure that 1/9 became the standard...

    MK 318 ammo Info 5.56

    Yeah, that's a part of it- for instance, the SOPMOD Mk18 MOD 0 was developed by Crane Division (Navy) for use by Special Ops units throughout the military (they don't just cater to SEALs is what I'm getting at). It's supposed to kinda bridge the gap between the M4/SOPMOD Mk1 and the M14/Mk14...

    MK 318 ammo Info 5.56

    Believe it or not, that wasn't the only reason. In late '06, they added an additional 4th Battalion to every SF Group, which necessitated a new numbering system. I don't know how long they'll keep it that way before returning to the 3 Battalion format, if they ever return to it. It really was a...

    MK 318 ammo Info 5.56

    Currently, I'm out- was injured too many times. The only unit I was assigned to that I can talk about was 2/27IN, part of 3rd Infantry Brigade Combat Team, 25th Light Infantry Division. I also did a lot of time at Ft. Bragg, back before they changed all the ODA numbers, lol. Now they're using...

    Do you use an adjustable cheekpiece on your rifle?

    You know, whenever I felt I needed it, duct tape and a ratty old sand-colored undershirt has always been the answer, lol. A lot cheaper than buying another stock and less time-consuming than rebedding and restocking a rifle. It was a field expedient way to add a higher cheek weld on the M24A1...

    MK 318 ammo Info 5.56

    Oh, and before I forget- the current generation of the AR platform in service with the US Military doesn't use a 1/7 twist barrel; we now use either a 1/9 (standard M16A4 or M4A2/3) or a 1/10 (SOPMOD Mk12 Mod 0). Sure, it's not a 1/12 or 1/14, which would tumble the round a lot, BUT, it's...

    MK 318 ammo Info 5.56

    AHHHHH.... See, I can only really testify to what *I* saw, over 3-years (over back-to-back deployments) in North/Central Iraq. And, unfortunately, as I said, that area is EXTREMELY dense in terms of urban population, which meant we couldn't just go droppin' 155's everywhere we went. God we...

    MK 318 ammo Info 5.56

    A .30-Cal bullet is problematic, at best; First and foremost, d#mned things are HEAVY- won't catch me carrying more than 200-250 rounds in that caliber. My average loadout as a team leader was 600 rounds of 5.56 in Iraq in '06, and you better bet I would use nearly every mag in a firefight. I...
