...joke was on me..tried to open up the aperture 1/64th...Armalite must have used Kryptonite Spring Steel... Finally made it but broke one bit and ruined another...

Papoose...have one and love it. Is very accurate and 100% reliable...

Nylon 66...had an Apache Black for years and it was also great. Saw one the other day for $350.00...was in nice shape. Another gun however that won't hold zero with a scope because the sheet metal cover covering the action that the scope is mounted to shifts. Also had the Nylon 11 that is a bolt gun that was a great shooter also...both went down the road...
