We all know AR-15's have accuracy wedges to take up any slop between the upper and lower. So what does the WK180-C have to get rid of that slop? Well, the ACCURACY HOOP of course!
Install one of these bad boys on the shark fin dangling out the bottom of your WK upper, and voila! All that unwanted slop is gone.
Accuracy Hoops are constructed from a flexible rubber that needs to be compressed (by hand) as you squeeze the upper and lower together. Be sure that the locking in, in the guide rod plate is engaged before you shoot.
These little guys will take up all the slop and then some! And the best part is no permanent mods are required. If you don't like the feel, simply remove the hoop and you're back to the good ol' sloppy WK that you fell in love with.
Note: You will need to squeeze the upper and lower together hard to take your WK apart for cleaning, but it's worth it!You get: (1) Accuracy Hoop Compatible with: WK180-C RifleTools required: None Installation Tips:

It takes ip the slack and stops the rattle but when installed the bolt hold open will not engage.
