So I'm doing a little research per say (basically killing time) on gunbroker and come across this ad...

AR-15 Rock River Arms RRA Stripped lower not Colt

For those that don't want to click on it...

Brand new Rock River Arms LAR-15 stripped lower. It is factory marked U.S. Property. It is a new lower and can be built into a rifle. It is also compatible with a DIAS. It has never been fired or assembled. These are hardly ever seen availible.

Can you believe there are 6 bids on this thing, the top bid being $181 and the reserve isn't even met yet!!! Why do people insist on bidding for things that they clearly know nothing about???

This seller (J&B Gun Sales Tulsa OK) seems like a really shitbag. First he pulls the "not a Colt" crap in the title making people who are searching specifically for a Colt still see his BS ad then lies about how common these lowers are and also lies about the DIAS (RRA lowers can not fit a RDIAS). Hell I guess I should give him credit for finding at least a few idiots to fall for his BS

As you said, I'm pretty sure that RRA lowers ARE NOT RDIAS compatible.  Unless it's modified, it has a high rear shelf.

Agreed:  Suckers
Agreed:  Shitbag dealer

I really hate those NOT WHAT YOU ARE LOOKING FOR ASSHOLES.

who can be sorry for those that dont educate themselves?

Maybe this is one of those uber-rare RRA lowers that DOES accept a DIAS .
