AM 77 FPS and manufacture

Picked up a pair remans to play with, interesting difference in FPS between the two, not uncommon by any means from what I have read. Used CPHP 7.4gr after cleaning. Overall I am pleased with the condition, a few blemishes here and there, a touch up here and there, nothing terrible by any stretch of the imagination.
Gun 1 730.6 Ave FPS / 8.77 FPE
745, 752.5, 749.5, 725, 725.1, 735.9, 718.5, 723.6, 716.3, 714.7
Gun 2 653.6 Ave FPS / 7.02 FPE
662.8, 648, 659.9, 659.4, 654.4, 653.7, 652.1, 648.1, 648.2, 649.4
There is a difference in construction, I am not a modder, but photos of the under side of the cocking arm,
Gun 1
Gun 2
Will be interesting to see which is more accurate, good fun for sure!
Best,
Tim

Decent groupings after sighting in the included little 4x scopes using Crosman pointed hunting pellet. I haven't tried any other pellets yet, and I am not sure I need to really. 10 yards in the dungeon, dots (stickers) are about the size of a penny. Looking forward to getting them outside for sure!

Nice buy, they're good guns. Looks like the one has an older piston with a new pump cup maybe, and is definitely throwing the pellets hard! Mine seems to like the cphp's.
