I don't own one, but those who do say they are one of the best kept secrets in the AR industry.
There are several Del-Ton threads going some of the AR sites where the opinion is that they are accurate, reliable and have good fit & finish. It's hard to beat their prices for what you get too. I especially like the way you can customize the product they put together for you at the Del-Ton Website. That way you get the AR that fits your needs best. I hear customer service is good too if you need any help.
There are a bunch of Tier 1 combat ready operators at those sites that are always ready to say that you MUST pay at least $2,500 for any decent AR and another $1,500 for optics, but the truth is for plinking and the average shooter the Del-ton will be perfect.
