My luck would be ****....
I hate to say this, as I'm not hating on "cheap" guns, but with AR's you really do get what you pay for. And like JMcMath said, for that price, you can either get lucky, or get screwed. Also, with AR's, when discussing anything other than the finish on the gun, the bolt carrier group, and the stock tube diameter, the term "mil-spec" is not necessarily a good thing...Especially with triggers and barrels. These days you can buy MUCH higher quality parts for a little bit more than mil-spec quality parts.
I know folks who told me I was crazy for building AR's that cost as much as mine did ($2K and up), until they shoot them...Then they're amazed at how smooth and accurate they are. Some of them still say, "You got too much invested in an AR rifle..." But most (the ones that know quality guns) admit and agree that they can see where the money went, and that it was worth it.
Here's my recommendation for a high-quality accurate and reliable AR that you WILL get your money's worth out of. LWRC builds THE highest quality AR-platform rifles on the planet...All the parts are precision-matched & hand-fitted. I'm proud to have had one of their M6 series rifles since 2009.
