"Needs modification. Not drop-in kit for WE 416c. Besides that, it does what it says in the description.
by John B. on 11/24/2020
"I bought this for a DYTAC SMR rail mounted to a WE-TECH GBB 416. It fits fine in the rail- a little loose, but a couple layers of electrical tape fixed that. However...the inner diameter of this barrel nut (that fits around the outer barrel) is NOT WE-TECH spec; it's too large. The result is that it barely grabs the flange on the outer barrel and does not hold it firmly against the receiver. The only fix for this is a strong washer that has both the correct inner and outer diameter, then shimmed to perfection with a pack of standard barrel shims (sold here). I say STRONG because I tried to use only barrel shims, but they're too thin and bend into the gap between this barrel nut and the gun's outer barrel- so a strong and correct sized washer will provide the right stiffness along with barrel shims. Well made, but unfortunately another may-need-modification-airsoft-part. Good luck cowboys!
