Yup, sounds like you did your homework pretty good!
You can get Lowers for $100- $105.
CMMG DPMS forged lowers
And you can get RR lowers for $100 everywhere.
The Jnt bull kits are sweet. Very accurate and quality materials. They will shoot with the best of 'em. Just a few hundred cheaper and minus the brand name stamps. They can even put it together for ya(the upper) and all you will need to do is slap the lower together /ubbthreads/images/graemlins/laugh.gif My last DPMS lower went together with a very expensive tool called "my fingers" /ubbthreads/images/graemlins/cool.gif
I do enjoy tooling arround with building but its so much easier to slap the upper n lower together. Wait did I just say I am lazy? /ubbthreads/images/graemlins/wink.gif
I would think anyone would be happy with the quality of a Jnt kit, any of them. Hopefully others will chime in with RRA lower leads. Dont pay over 100 bones /ubbthreads/images/graemlins/smile.gif jerryboy
