This is a Colt Diamondback 22 magnum.

Before everyone tries to tell me the history of the gun and it was only marked magnum but still jus an lr, I promise you it's a real magnum.

Back in the 80's my best friend and I bought these from Stockade in Westminister California. 

We then took them to Bolsa gunsmithing in Westminister and had them rechambered for 22 magnum.

My freind recently passed away and hus sister gave me his gun.

I'm am selling one of them as I don't need both of them. 

They both have around 500 rounds through them and are still in like new condition with all paperwork and original box.

$4000.00
