MadBull Airsoft sent us news, errr... a rumour that you can fit regular handguards from other brands unto the Western Arms M4 GBB by using their Delta Thread Ring Modification Tool... "Gents, One of Airsoft players share this information with us: WA M4’s delta ring adapter is 0.3mm thicker than regular M4 (CA/ TM/ Real M4) adapter. When you install a standard dimension handguard rail (like most of the brands), it won’t fit.

So, this guy used our Delta ring modification tools and modify his own WA M4. Now, he can install regular handguard rail!!! This may be a solution for all WA M4 users.

We don’t have a WA M4 …so…try at your own risk."
