The 2lb Trigger spring that I sell makes your Remington 572 feel like a new gun. Be sure to thoroughly clean your trigger group when installing this spring. If it's worth doing... It's worth doing right... My friend Mike who lives in Oahu HI had some issues that turned out to be cleaning.
I offer the springs is 3lb, 2lb for $6.50 ea + USPS Priority Mail of $10.50. Mail your order to springs@ccskeet.com. I accept personal checks, or Pay Pal "Friends & Family" which has no charge to me...
