I had a Colt but the only thing Colt in that rifle is the name, they are made by Walther then imported by somebody else. The barrel is thin with a sleeve, the bolt doesn't come out for cleaning. I don't recommend buying the Colt as don't think will last and or easy to maintain, I try several of the .22 platforms Sig 522, Colt M4, Ruger 10/22, M&P 15-22. The M&P 15-22 I like the features and how is put together, it uses all the accesories of the regular AR15 so the sky is the limit to make how you wanted. I put thousands of rounds down range with no issues is light and everything is the same place as the the AR15 so I practise with the same platform that I use for SD so to me is the best choice out there but that is just my opinion.
