A smarter spring guide
Standard spring guides ignore a basic problem: as a spring is compressed and released thousands of times, it twists. That twisting means friction, heat and premature spring failure. The ASG Scorpion EVO steel spring guide with bearing fixes it.
Steel strength, POM smoothness
A high-tension steel core gives the guide the strength to handle serious power, from M90 all the way up to M190 and above. The outer section carries a free-rotating sleeve made from POM polymer that lets the spring rotate as it compresses.
Real performance gains
Combined with a supported thrust bearing, this arrangement dramatically reduces friction and heat build-up. The result is longer spring life, plus measurable increases in rate of fire and muzzle velocity.
The easiest upgrade you will fit
Best of all, the EVO spring guide can be removed and replaced without stripping the gearbox, so this is one of the quickest performance upgrades on the platform. See more airsoft repair and servicing if you would rather have it fitted for you.
