AKS-74U lower handguard retainer insert

A simple solution for a common problem. Tokyo Marui copied AKSU with the wrong lower handguard length, 125 mm if you measure the part that's visible on the outside, instead of the correct length, 120 mm. Every airsoft manufacturer that copied this detail from TM, like E&L, WE, WELL and so on, has a slightly longer handguard, making the process of installing proper length lower handguards hard or impossible.

I designed a small insert so that you can use real steel, LCT, cyma etc handguards on your TM, E&L, WE, WELL etc. On the pictures you can see a special insert for installing the real steel VS-27SU handguard.
