updated V2 the rail and the support ring is now separated. you can tweak the size of the support ring and print out for testing instead of printing out the whole rail. V3 in progress - will be without the support ring with tweaked TopLock which required 4x M3 hex nuts this is the replicas of Ergo M4 Handguard Extension Rail that I made. They will work on the airsoft M4 both AEG and GBB. It contains both AEG & GBB versions in separated STLs. These are the lists of airsoft guns that were tested; TM M4 MWS JG/Double Eagle M4 GBB Classic Army M4 AEG G&P M4 AEG E&C M4 AEG BEWARE ! the support in the middle of the rail may needs to be filed off a bit in some airsoft brand. It depends on the shrink rate of your print too.
