Abstract

A gun conversion kit having upper and lower chassis that fit together on upper and lower surfaces of a 10/22 style receiver. Tactile feedback surfaces facilitate finger positional awareness relative to various receiver parts. A barrel thread and spacer arrangement on the upper chassis allow connection to AR4 style handguards which conveniently align with a picatinny rail integrated into the upper chassis.

Claims (10)

1. A gun conversion kit comprising:

an upper chassis adapted to matingly fit a top portion of a receiver;

a lower chassis adapted to matingly fit a bottom portion of the receiver;

the lower chassis being removably secured to the bottom portion of the receiver by a takedown screw disposed through an aperture in a protrusion disposed proximate a front portion of the lower chassis, the takedown screw engaging a cooperating hole in the bottom portion of the receiver;

a front portion of the upper chassis having barrel nut threads adapted to threadedly engage a barrel nut.

2. The gun conversion kit of claim 1 further comprising:

a barrel spacer disposed axially between the barrel nut threads and a portion of the barrel nut;

said top portion of the upper chassis having an integrated picatinny rail.

3. The gun conversion kit of claim 2 further comprising:

a distance from a top surface of the picatinny rail to a center of a bore of the 10/22 receiver being configured so that a free-float handguard with a second upper picatinny rail will be axially substantially flush with a front surface of the upper chassis, and vertically even with the top surface of the integrated picatinny rail.
