FMairsoft33 Posted September 13, 2023 Posted September 13, 2023 Hi guys, I have a very basic understanding of airsoft teching, so bear with me if I'm doing something stupid. I have recently bought a second hand Tokyo Marui M4 AEG, I'm not 100% certain but I am pretty sure it's a tokyo marui m4a1 carbine aeg. I am trying to remove the inner barrel but can't seem to get the upper and lower receivers to separate, I have removed both body pins and am pulling the charging handle as you usually would, and there is a little bit of movement, but they won't separate as they should. The gun has had a replacement stock and front handguard as seen in the picture, so not sure if that makes a difference. Any help would be massively appreciated, thanks!
SSPKali Posted September 13, 2023 Posted September 13, 2023 Is it a polymer body? It might be the older type with “rear ears” that the rear body pin goes through. These you only need to remove the rear pin and carefully pivot the upper around the front pin. Search out the TM M733 AEG manual for instructions and pictures. FMairsoft33 1

Has someone changed the hop unit? The original is a two part unit that should come apart when you split the receiver. If it's the original receiver but an aftermarket, one piece hop unit then the hop unit itself may be getting stuck as the receiver has a different profile. FMairsoft33 1
