Reviewer: Christopher Barr from Englewood, CO United States  
Air Rattle sent 2 Modify M130 Springs instead of Madbull.  When I called I was informed Madbull was out of stock.  The springs were ordered for a game and replacements would not be available in time.  I was refunded for my order and allowed to keep the modify springs.  Excellent customer services to make up for the mistake.

For those long distance shots or extra punch, this spring is worth every penny.
