BT M16 barrel kit modded to fit straightline barrel

i was able to file the inside of the spring loaded handguard mount to fit over a straightline sizer adapter. the handguard mount now fits over the sizer and barrel collet to fit flush with the A5 body. Looks awesome!!! i also added a weaver rail cover to the top of the marker and fitted the M16 style carry handle. This allows quick and accurate ADS while wearing a paintball mask. Just what i was lookng for.
recently i added the metal M4 style grip and also got my grinder out and cut off the tang that sticks down in front of where the vertical grip used to go, then sanded and painted the area.
