AntTech Spring Guide Lug Nut for M4 HPA Builds

Most Airsoft M4 replicas require a spring guide to mount your buffer tube to. This includes HPA builds that have no need for a spring guide.

Un-modified spring guides are capable of damaging expensive HPA engines, and in many cases are impossible to hold in place in the absence of a spring. 

Gone are the days of taking an angle grinder to your OEM QC spring guide just to be left with the new problem of retaining that spring guide while you mount your buffer tube. 

The AntTech Spring Guide Lug Nut for M4 HPA Builds seeks to solve this problem! We offer multiple variants covering the most common gearbox shells that we see used in HPA builds!

This simple part consists of the plastic body that is solidly printed with a rigid, UV/Chemical resistant, high melting temp PETG and a steel hex nut. These components come together to provide a durable mounting solution with the added feature of LOCKING into your gearbox shell!

Save yourself the time and heartache. You are worth it.
