    XM7 worries from the field.

    I had zero input into SR-25 and M110 development, nor have I ever claimed to have had any. I did closely observe the life of the SR-25 and subsequent models from start to the current iterations, with more than enthusiast access, but not directly involved. You just mentioned how M110 turned out...

    XM7 worries from the field.

    ATF started getting funding in 1981. Prototypes weren’t ready until 1990 for DEM/VAL. I don’t think it’s unreasonable for the Army to expect faster timelines for small arms, but also keep in mind the XM4 program basically covers the ATF developmental timeline, and wasn’t made until 1994. Most...

    XM7 worries from the field.

    I mean, what’s not to like about a 270 Magnum 10.5” carbine? Your comments are insightful about RDT&E and TRLs. In USAF, there are parallel TRLs that are understood to be on continuous paths of aggressive development, whether they be propulsion, Radars, materials science for structures and...

    XM7 worries from the field.

    That was at a LGS in Fayetteville working as a civilian. The guys did their transfers through the store once KAC sent all the rifles there. Has nothing to do with RDT&E, just noting one specific time frame where I saw a lot of different 1st Gen modified SR-25s pre-M110. I have done RDT&E and...

    XM7 worries from the field.

    From the early 1990s up through Mk.11. I enlisted in 1993. The only SR-25s I saw in the 1990s were pre-rail, pre-brass deflector, with the old black fiberglass tube handguards. I think the first time I put hands on a Mk.11 was in 2002. They were even for sale on the civilian market at the...

    XM7 worries from the field.

    While JSOC moved-on years ago, SOCOM is still messing around with awarding 2 different contracts for a 14.5” 6.5CM SR-25 basically, with 2 different barrel attachment methods. So SOCOM seems to be infected with the same bureaucratic conundrums big Army has.

    XM7 worries from the field.

    I lived though it alongside everyone else. End result was the guys who typically used actual SR25s went 6mm ARC in small frame guns in the long-run. Big Army required HPT for the bolts on the M110, again another nail. Early SR25s had some issues like anything else. JSOC had theirs all tuned...

    XM7 worries from the field.

    The difference is that after Army Ordnance Board under Dr. Carten officially declared the AR-15 totally unsuitable for military use and sent his findings back to the Pentagon, then the Ordnance Board received orders to begin type-classification of the AR-15 as the USAF’s new service rifle...

    XM7 worries from the field.

    Yes, I’m tracking that. I was never a fan of the M24 conceptually or in execution, even though it was as you describe. I was always a gas gun proponent, and became a fan of the SR-25 once it was unveiled at the time. Once I started shooting my 16” Grendel beyond 600yds, I felt cheated for...

    XM7 worries from the field.

    Another example where Big Army bent SF over in small arms was with the LMT Enhanced BCG for the M4. It was a good, working solution for the excess gas from the CLGS and especially CLGS + KAC QDSS NT4 suppressor, in addition to a bolt that wouldn’t break within 6-12k rds. Big Army said, “But if...

    XM7 worries from the field.

    I remember that (I kept tabs on each year’s International and SF Sniper Competitions), and heard similar details about PSR FUBAR from other guys in this very thread who had close proximity or inside FOV. The one that stood out more to me was the Team who won using 7mm SAUM AR-10s back in the...

    Shouldered barrel AR15?

    Yeah, it’s so simple and effective, very easy to change with consistent torque applied by the provided wrench. The slot cut allows clearance for insertion and removal, as well as pinch torque around the extension. If we could go back to Stoner in 1955, sneak into his drafting room, take away...

    Thread-swerve: Take any money you’re spending on beer, dip, cigarettes, peyote, weed, coffee, whatever you’re addicted to, and put it into investments. There are more opportunities to make money now that any time in history, and you’re in the best position if you live in the US due to how...
