AnK M4 CQB Wobble Fix
By:Well_Boy

This is a DIY solution to that irritating wobble on the AnK M4 CQB airsoft rifle....You'll only need strips of electrical tape for this fix and it'll reduce the wobble down to about 97%.

This fix focuses on the wobble on the outer barrel and upper receiver assembly. Here are some pics.

Two halves of the upper receiver

Outer barrel assembly

Apply some electrical tape then test-fit. Repeat process until satisfied with the fit. Remember that when conducting test-fit, make sure that the two halves of upper receiver are securely screwed to the barrel assembly, with the top-rail installed and the allen screw atightened. The top rail should fit in nicely to the upper receiver after putting some strips of electrical tape... IF it doesn't fit remove some electrical tape then test fit again...
