G&G AEG Piston Spring Guide III

Upgrade your plastic spring guide to the G&G Version 2 Spring Guide with ball bearings. Stock spring guides can break easily, especially on upgraded guns. If your gun is shooting above 320FPS with .20g BBs you absolutely need a G&G spring guide. The ball bearings on this model are especially good for upgraded guns because they help reduce tension on the spring by allowing it to spin freely, thus reducing the probability of the spring breaking.
