Title: AM 77 FPS and manufacture
Post by: CFH on March 19, 2013, 09:08:17 PM

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 2 653.6 Ave FPS /  7.02 FPE

There is a difference in construction, I am not a modder, but photos of the under side of the cocking arm,

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.
