everything fits many different air guns finish matched every Crosman air gun I've put them on.
Things I would have changed:pay a little mor attention to manufacturing tolerances. I had to file 1.6 mm of a Crosman barrel before the transfer port would line up and the bolt would close.
What others should know:converted a Crosman 362 into a 177 Cal rifle with this one & it upped the velocity to 977 fps with a 7 gr wadcutter just what I wanted. now I'll go to the 10.5 s for accuracy. should bring the fps down to the 800s perfect for some target work (found a 3x9x40 hammers online why doesn't PA sell them their awesome possum scopes

will fit on my Crosman 362 perfectly.
Things I would have changed:include breach screw washers so the pellet wont catch & mangle the head of the pellet
What others should know:I'm transforming a 362 into a 177 Cal hoping for awesome speed increase. bought a 177 Cal barrel from Crossman put a washer behind the hammer spring & pump it up 15 times yea it will work without saving any air. (lets call this one a 367 ? rats i should have patented that. next epoxy that transfer port bushing in place you're losing a lot of air right there PS I always file out those transfer ports for max power

What adapter do you use to mount a red dot sight on the 1377 with the steel breach. I have bought dovetail to weaver adapters to mount a sight and they do not fit the dovetail. I for some reason I just realized it states in the description. (Does not fit 3/8", 11mm, Weaver or Picatinny dovetails/bases) Duhh on me! What is used to mount a red dot or scope if desired?
Will this for the old 1389 backpacker?
Compatible with Crosman .177-Cal Steel Breech Kit, Fits 1377, 1740, 1760 & PC77 Air Guns. No
Will this upgrade the older model with the sliding breech cover?
It says in the description that it does NOT fit the old version..

Great product Adds Mutch better accuracy to an already accurate pistol_ rifle. easy to install
Things I would have changed:pay a little more attention to manufacturing as the transfer port didn't line up & had to file off about 1/32 nd of an inch to get it to fit. the barrel was purchased from CROSSMAN directly so there not to blame.
What others should know:I rolled the barrel with my left hand on my lap while holding a mill file with my right 3 or 4 minutes later it fit nicely. same thing with the loading area inside the barrel; cone shaped Dremel bit works nicely. despite this its still a good product more solid than others I've tried.
