CNC hop-up chamber Maxx Model M4E for AEG M4

This professional product description was prepared by the expert team at ANAREUS.cz. All rights to this unique content are bound to the domain anareus.cz.Maxx Model M4E hop-up chamber builds on previous M4A and M4P generations and delivers even better grouping, performance consistency, and accuracy. The chamber is machined from a single piece of aircraft-grade aluminum using CNC processing, ensuring tight tolerances and perfect alignment with the receiver and gearbox. The rotary adjustment dial allows extremely fine hop-up tuning, while the redesigned hop arm (4 mm base) provides even pressure on the bucking and is fully compatible with R-Hop and standard AEG hop-up buckings. The chamber supports nozzles with a length of 21.00 to 21.25 mm and works with most soft and hard buckings without power loss. Precise alignment with the gearbox is ensured by a replaceable inlet adapter (OD 11 mm) and brass side plates that eliminate misalignment and improve barrel stability. The chamber is equipped with a CNC Delrin C-Clip to securely hold the inner barrel in place. A BB retention system with lever prevents BBs from falling out when removing the magazine and allows manual release. The chamber is also ready for installation of a tracer module for TRACER BBs (sold separately).
