Vipertech Buffer spring (regular/medium/winter)

-Purple PVD coating.

-Stainless steel.

-Winter spring is 2 pounds and 5 ounces at 8 inches of travel making it great for a super efficient Vipertech!

-Medium strength spring is 3 pounds any 8 ounces at 8 inches of travel making this a good option for in between an efficiency spring and a snappy cycling spring.

-Regular strength spring is 4 pounds and 8 ounces at 8 inches of travel which is just about identical to the stock Vipertech buffer spring! (Only it’s purple so it must be better!) These are a great option for VFC AR owners that want a snappier cycling with their gun!
