Used RTB many of times. Great stuff. Never any issues. Killer deals.

As the ad says, they take another 15% off in the cart. With shipping, three at $116 each with the upper completion kit -- that's a steal

$131.80 before shipping if you include the basic dust cover and forward assist kit. Not bad.

I agree. These should be comparable in quality to PSA. RTB stands by their products and are quick to fix any problems.
