    XM7 worries from the field.

    Imagine 1.4 million Chinese infantry equipped like us. Their basic rifle qualification starts at 200 Meters and closes to 100. The PLA is receiving the first of 1.4 million sets of SAPI plates this year. High-cut MICH helmets fielded in 2018-19. They're starting to get night vision. The...

    XM7 worries from the field.

    SIG keeps winning Army contracts because they keep delivering exactly what the Army asks for. Nothing really sinister about it. Competition would win if they did the same thing, but aren't. Jason St. John came from 3rd Ranger Battalion and the Army Marksmanship Unit. He, Robby Johnson, and...

    Anyone Shooting a 40x?

    Nice AI summary: "Remington introduced the swept-back bolt handle on the Model 700 in January 1962. This was part of the overall design of the new rifle which included a more streamlined tang and graceful trigger guard. The bolt handle was further swept back in 1969, but changed back to a...

    Anyone Shooting a 40x?

    My ex-GI $400 CMP surplus 40X in an H-S Varmint stock set up with irons for mini-Palma (.22LR at 200 yards using the standard NRA 200-yard highpower target). I put a Murphy Precision 20-MOA base on it to mount a 10X Tasco Super Sniper for 100-yard practice. One of my nephews:

    M40A1 USMC spec clip slot drawing.

    Merry Christmas. Note the scope base and iron sight base holes are the original 6-48 and not the naval-military 8-40. M40XBs, 40Xs (both centerfire and rimfire), and M24s had the iron sight base holes on the aft-left of the receiver (700s were NOT drilled and tapped): What goes in the left...

    M110 optic history

    Infantry snipers are not USASOC (Ranger, SF, and SMU) snipers. Vanilla Army frowns on innovation and initiative so I doubt they used any variations. SOTIC (now SF Sniper School) was influenced by SMU snipers who had contracted Todd Hodnett for training around 2008-2010. Todd introduced them...

    M110 optic history

    The US Army fielded M110 with the Leupold M3LR as specified in MIL-PRF-32316 (AR) w/AMENDMENT 1, 5 October 2009 (superseding 7 October 2008). People confuse the KAC M110 (Army contract) with the USSOCOM SR-25 (1993-2000) and Mark 11 (fielded in 2000). M110 users might have US Army tapes on...

    Joseph Wambaugh

    Growing up I read most of his books and watched "Police Story" every Tuesday night. I saw Johnny Carson interview him on the Tonight Show. Many knew his name but had never seen his face. He relayed how, after a full law enforcement career, he was speeding and got pulled over. Embarrassed and...

    M40 orphan is home

    Standard M24s are long action. You can visually recognize the USAMU short action M40 - M24-ish rifles by the slightly narrower-lighter barrels, 10-shot single stack magazine, and Leupold illumination knob. If the original Remington air force barrels were excessively worn they were swapped...
