King Arms Metal Hop Up Unit for M16

Product Information:
great unit.one of the best upgrades i put on my gun.when i put a g&p metal receiver on my jg m16,i quickly realize that the g&p hop up unit was garbage,after about 50',my shots were all over the place,and i couldnt hit anything.when i got the king arms unit in the gun and adjusted it perfectly,,my accuracy,range,and power all increased.as someone said before,the springs that come with the unit are too big,so you have to crush the ends on them to fit right.as someone else also mentioned,this gears that come with this unit arent blue like pictured,they are black.thats because the picture shown is of a g&p hop up unit.you can tell the difference,because the barrel clip on the king arms unit is shaped wierd.there are 2 little studs at the top of the clip on either side of the clip which are supposed to hold it in place better (i guess).its a real pain in the but to get in,and could possibly break if you put too much pressure on it.if you plan to use this with a tightbore barrel,make sure you get the barrel in this first,before you put it on your gun,otherwise youll have to take the barrel clip back off,and it will probably break.other than that,its a great addition to any m16

once set,doesnt unadjust itself.

barrel clip is a very unique desing,is can NOT be replaced with any other barrel clip.you MUST use a king arms replacement if youre breaks
