hen you order the spring pin that holds the M240 machine gun’s fring pin in the
operating rod, you may get one that’s too big to ft. (The pin, NSN 5315-01-033-
8873, is Item 4 in WP 0037-001 in TM 9-1005-313-23&P.)
IF that happens, substitute the spring pin, NSN 5315-01-033-3889, that’s Item 5
in WP 0044 00-3. Cut the pin in halF so that you have two pins 16mm (0.63 inch)
long. ±ile a chamFer around the end oF the pin. You now can install the spring pin in
the op rod.
Dear Half-Mast,
When I try to order the cap screws for the
MK 19 machine gun’s control grip assembly
(Item 10 in Fig 8 of TM 9-1010-230-23&P),
the NSN doesn’t show up on FED LOG.
What is the correct NSN?
