Wolverine Airsoft has outdone themselves once again to provide airsoft enthusiasts with innovative upgrades to some of the most popular styles of rifles to fully maximize their full potential. This conversion kit included everything you need to convert your compatible spring powered airsoft sniper rifle into a HPA powered machine. An included specially designed air attachment system makes for a quick swap when using a standard spring. The BOLT-M system is fully mechanically, eliminating the need for a battery power source much like other HPA kits. Using a smooth cycle bolt makes for quicker follow up shots without dealing with the recoil when using standard spring operation. The overall simple design of this HPA kit makes for a quick and easy installation or breakdown for simple maintenance needs. Here at Airsoft Station we carry a large variety of compatibility options for this HPA kit, so make sure we support your rifle model before purchasing. Satisfy your need for more power and accuracy by upgrading your compatible airsoft sniper rifle with the new BOLT-M HPA Conversion Kit from Wolverine Airsoft.
