Custom built China lake launcher by Renegadecow. I realize some of you have seen this before, but for those of you who have not, its pretty cool.

Another grenade launcher from Renegade cow(Im a fan of this guys now). This one is the Vietnam XM148 which came before the more popular m203.

This next one is a custom built AW50 that a guy built using a star aw338. Its just a cosmetic upgrade but it was done very well IMO.
