Do you have a DAQ or AS2250 Breech? You can use my Bolt/Handle with other steel breeches. My bolt has a radiused tip and is longer than the factory bolt. The advantage is that a longer probe pushes the pellet past the C02 hole and into the rifling for better engagement. Having a bigger diameter handle lets you grab the bolt with your hand, not just your fingers........People have asked me to sell this separate so here it is, O-Ring Included.......$20.00 Dollars Includes shipping. Bolt is Brass....and Handle is Stainless Steel now!
