Q: What is this
A: This is a conversion kit for the older style Crosman 1377. If
your older Crosman has the sliding breech cover and rear cocking knob,
this kit will replace the system with the current-production plastic
breech and bolt.
Q: Will I still
need to cock the gun via the rear knob?
A: YES YES YES - The new bolt serves only to seat the pellet and
seal the breech. It will NOT cock the gun. You must still use the rear
knob to do so.
Q: If I still need
to use the rear knob, what is the point of this kit?
A: Aesthetics, mainly. I have had countless requests for this
kit, so here it is. You also do gain the convenience of a simpler-to-use
bolt vs the sliding breech cover.
Q: Nonsense. I
don't want to use the rear knob. Help!
A: You're going to need a new main tube, hammer, hammer cover,
etc. At this point, you may as well buy a new gun!
Q: What all is
included with this kit?
A: You will receive: 1) Plastic breech, including bolt, rear
sight and screws 2) Replacement 1377 barrel with enlarged transfer port
3) Current production transfer port bushing.
Q: Rear sight?
A: The steel breech kit does not typically accommodate any
rear sight except the LPA MIM or Williams. The standard plastic sight
will NOT fit. You can also mount a scope, which is mainly what
this kit is designed for. However, as of April 2016, Alliance Hobby does
offer a proper plastic rear sight for an additional $20.
This applies only to the
steel breech kit. The plastic breech accepts and includes a rear sight.
