Manufacturer claim
- All legacy OPS/AE brakes and collars still work — everything is completely interchangeable with the OCM5.
- Full auto rated, with a lifetime warranty for all reasonable non-negligent use.
- All OCM5's ship in an 11x8x3 Eylar protective gun case with stickers; no mounts are included in the box.
- No shorter than 10.3 inch barrel when using the Otter Creek Labs PTB mount; no shorter than 11.5 inch barrel when using the OTB mount; a more conservative full auto firing schedule is recommended on the OTB mount under 12.5 inch barrels.
