Maxx CNC Stainless Steel/Aluminum Spring Guide

The Maxx CNC Stainless Steel/Aluminum Spring Guide is a well-machined internal upgrade for airsoft players building or servicing an AEG Version 2 gearbox. Designed to keep the spring properly aligned while allowing it to rotate on the shaft during compression, it supports smoother gearbox cycling and helps reduce unnecessary strain on the spring in higher speed setups.

Maxx uses a stainless steel and aluminium construction to balance strength with low weight, coming in at just 14 grams. The stainless steel hub features an M5 thread to secure the stock firmly, while the thrust ball bearing is there for a practical reason: it helps the spring turn more freely under compression, which can reduce twisting, stress and premature breakage during hard use.

This version uses a 16mm hub outer diameter with a 10.8mm shaft outer diameter and an overall length of 51.5mm, making it a specific fit for compatible Version 2 gearbox builds. The chamfered stainless steel hub shoulder also adds durability where it matters most, especially for techs looking for dependable internals rather than generic replacement parts.

A smart choice for gearbox rebuilds, performance tuning and other AEG internal upgrades alongside springs, piston sets or bushings. Add it to your parts box when you want a cleaner, more controlled spring setup.
