Mini Tungsten Spring Follower 22 Magnum

Mini Tungsten Spring Follower replaces the small Brass follower to add additional mass to the bolt recoil. This is designed to help support the tuning of .22 WMR builds.  We hope this new part will assist with pre-mature bolt recoil. The units are solid Tungsten and the weights very from 44 grams to 54 grams. The stock main return spring (large spring 2.7 lbs under the rail) needs to be trimmed to 39 coils or less in length. It can be stretched to gain the required return pressure. Or you can order one of our heavier 3.1lb or 5.1 lb return springs. If needed you can use a heavier Tungsten Follower.  WARNING: You will still need to trim large return springs down to a minimum of 39 coils. WARNING, You must check the bolt return cycle when installing this part to ensure your bolt has full rearward travel. If it does not, trim your return spring as needed.
