Invert 3 Piece Bolt Spring Kit - NDZ

Thats right, its finally here. The long awaited MINI bolt spring kits. Each kit includes 3 different force springs, from hard to soft. All springs have LESS force than your stock MINI bolt spring, its a tuners delight. This kit is optimized for use with our Delrin V2 bolt for reduced input pressures, reduced firing signature, improved shot consistency, reduced bolt wear while reducing mass. Check the forums, this is what people are talking about..

• each kit contains 3 spring, each with a different force
• color coded for easy identification
• lowers your input pressure and dwell when used w/ V2 bolt
• improved shot consistency
• lower pressure is easier on paint
