Designed these from pictures to fit my Bulldog AEG AK-47. No idea if they're dimensionally accurate to the real thing, I just designed these in proportion to my AK. Take a look at the models and check if they will fit your model.
The lower handguard is designed like a B10U with slots for thin M5 nuts to mount the separately printed rails.
To mount each rail, you need:
It doesn't sit straight enough to use a laser properly, not sure if that's the mounting method, the print itself or the mounts for the laser I made.
The pictures were also taken before I got the countersunk bolts.
step files included so you could change the mounting hardware if you wanted to.
