These action springs by Pioneer Gun Works are machined from high strength steel and include a tension rod tuned to provide a light feeling action and reliable function. They are threaded to accept Uberti screws and Pioneer Gun Works American made screws. Screws are not included. These will only fit Uberti made rifles.
ATTN: Critical Installation Step: Before installing the Action Springs, make sure that the lever cam surface is smooth, polished, and without a sharp edge that could cause the pivot arm tip to wear.
