Looking for 10/22 owners who would like some improvements done to their rifles.I have done all these upgrades to my guns with great results! Upgrades : * Extended charging handle,helps to cycle your bolt so much easier.....$25 * Radius lower bolt edge to make smoother contact with hammer....$25 *Bolt lock-up & release, one-hand operation (similar to Tandemkross"bolt-keeper")....$30 Just some services I can perform...... I would be doing the upgrades on customer-supplied parts, shipping at customer expense ...I live in Olds if drop-off is possible. Please inquire if interested.... All upgrades have been safety tested...Have a great day! UPDATE......DEC. 31/23 Added pics of Bolt Lock-Up item as well as Receiver Bolt Radius (not my Pic).
