I heard lots of bad review about this but I thought i give it a try.. This is the Version II that i received. I installed this to my ICS M4 and it improved the grouping drastically.. Pros: Cheaper than other tight barrels Increases accuracy Increases fps by 5-10 fps did i mention cheap.. Cons: Needs to be properly installed.
