im printing a hoffman sl308 lower to do a raptor build. 375 raptor is kinda like 300 blkout but for ar10 platform. swap the barrel on your ar10 and your gtg. subsonic 440gr gr and hyper 150gr. 30 rounds of 400gr anyone? i just couldnt get it up for 8.6 blk. anyway once i figure out how to print ill start it. doing the 3dp orca right now. i did test parts to tune the print so il reprint all these in 2 color, screw those little boats. i think i have all the plastic internals for the glock. cool shit. amazing times. .
