Not long ago I purchased a Doublestar M4 on a whim. Seemed like a pretty solid rifle, made in the USA, figured I'd roll the dice on it. So far I've been very please with this rifle, haven't had the first problem with it (knock on wood.). Got a lot of crap from my shooting buddies for not buying a 'Big Name' AR, but when the dust settled at the range my "no name" outperformed 2 Bushmasters and a RRA AR. I should say that I just had less problems than they did. I went home and did a little research and it seems that Doublestar was a parts contractor for Colt. It said that they used to make the Colt lowers. Can anyone confirm or deny this? Seems like very good quality build and parts. If nothing else I am very pleased with a no name AR and would definitely buy from them again. Just wondering if anyone else has any knowledge or experiences with this brand?
