OK as too the Crosman red dot the screws for windage and elevation can be loose. Once you have it sighted in put a dab of fingernail polish at the screw heads to keep them in place. Crosman intermounts work best with the filler strip they used to use but a strip of inner-tube under each one will keep it from rocking and change the screws to hardend ones as the ones they use will snap before you can get them tight enough.
Excellent choice, i.e., the 1377C.You may want to consider adding mods. There are many.Good starters are a cocking arm pin to reduce wobble.http://www.mellonair.com/index.php?p=1_12_Solid-PinsA steel breech, available from Crosman, is a stable platform for mounting a scope. Longer barrels are available too. The trigger can be improved by lightly polishing it & the sear, & doing work on the spring. You can increase the power with a FT (flat top) piston & valve. Search the forum for details.A Crosman 1389 forearm will make pumping easier & reduce the possibility of pinched fingers, and a Crosman shoulder stock. The 1389 forearm is $9.45. The shoulder stock, as a Crosman parts order, costs $10.87. Otherwise, it costs $26.59.

Great advise, Do you have a picture of a 1377C w/ this setup?
