Been running one of these attached to a Geissele MK4 for a little while now. It's a very comfortable and light weight option for those who like to use a stubby VFG for back pressure. It weighs in at 1.5 oz and is about 2.25" long. No extra rails are need to attach it to both picatiny rails or smooth handguards. All attachment hardware is included, even for keymod.



Mine has been stippled and mounts up very solid with no gaps, after minor modification. To mount it to a Geissele SMR the top slot was opened up to 5/8" with a Dremel. This is my new little favorite VFG. $26.95 shipping included.
