This is an improved hop-up arm design optimised for SSX23 (it also works just fine on TM MK23) when using TDC hopup system. It's made out of solid CNC-machined aluminium and is known to increase the consistency of the SSX23 hopup chamber due to having no flex and a larger concave contact area . The design is based on the well known H-Arm by Hadron Designs and improves in several key areas: it's made for a tighter fit for clone (non-TM) hop-up chamber so it's always perfectly aligned and centred nub contact surface to bucking has increased by 33% to allow bucking to apply hop more evenly nub height has been increased by 50% to make sure that only the nub touches the bucking and the plate doesn't start deforming the rest of the bucking near the nozzle nub is better aligned to the SSX23 / MK23 barrel hopup window start of the nub is rounded to gradually apply pressure to improve hop consistency Compatibility This CNC Hop arm will fully work with all these models: SSX23 and SSX23 v2020 SSX303 (requires Mini Thumbscrew or shortening of original thumbscrew) Tokyo Marui MK23 All clone MK23's like ASG, STTi, etc.
