Last crawled date: 4 years, 10 months ago
Modified Caliburn Rival Reciever
(Upper+Lower Magwell)
Reinforced
areas around takedown pins thickened to address cracking issues
Upper + Lower directly bolted together as a Unit, to allow strong print orientation of Lower to relieve stress on Upper.
Dart Tooth cutout reduced in size; Dart Tooth spring Internalized. Both for better appearance and stronger structure.
nut access ports for front barrel lower threaded rods now internalized
Picatinny Rail raised 3mm to avoid Print Artifact of thinwalls around rod channels.**(will look odd in combo with non-Chunky rear-ends; may interfere with some cosmetic shroud kits)
Overall Receiver Length Shortened -because I have short arms and wanted to move the pump grip backwards. **not guaranteed to have full compatibility with general release front barrels.
Parts should be printed in the Orientation provided
supports needed for Dart Tooth and Mag Release
Upper + Lower no supports needed.
Additional Hardware (Beyond standard Caliburn Kit)
2x 5x30mm bolts (for bolting upper+lower together)
2x 5mm nuts
1x Volute Spring - harvested from Bicycle Quick-Release Wheel Skewer Rod** (used for internal dart tooth spring)
