175-MM GUNNERS...

 AUTOFRETTAGE TUBES
 ARE COMING

 WOT KINDA
 TUBE- LIFE
 YOU GET ON
 THAT PIECE?






 A new M113E1 autofrettage tube for your M107 175-MM SP gun is the latest
round of good news to zero in on gunnery circles these days.
 This El model will almost double interim tube life by letting you reach 700
effective full-charge rounds between trade-ins... compared to 400 EFC rounds on
the current M113 tube. So, you don't have to ask for tube changes as often.

 You'll only be able to tell the differ-
 ence by the bell shaped muzzle on the
 autofrettage tube. But your supply man
 will know the difference by its FSN:
 1025-113-5636 for the complete can-
 non, including all breech components M113 M113E1
 ... FSN 1025-113-5637 for the tube 400 EFC 700 EFC
 only. ROUNDS ROUNDS

cartridges in the M79 could damage
both you and the launcher.
