Sometimes a pain to get the hopper out of it.
Install (see below)
What more can I say? Excellent design, fits the Halo-B snuggly. Doesn't allow the hopper to move while locked on the field. However, sometimes the hopper takes a little effort to get out, but I'd much rather have that than the hopper being able to come out easily that's for sure.
Installing was easy, but to get it screwed on tightly is a bit of a trick. The inner tube isn't bonded to the outer locking casing, so it can rotate around. Easy fix, clamp your hopper down really tightly and crank the feedneck on tighter using the hopper.
An absolute must if you own a shocker (the stock feedneck will not fit the halo). Also a must for Ion owners. My friend could only get the halo to fit by removing the o-rings in the stock feedneck, even then it was flimsy.
Amazingly, found a pewter one that matched my shocker perfectly. What more can you ask for?
An amazing feedneck that does what it should flawlessly. The perfect feedneck. Buy it.
