I have both and having a new match rifle built up on a rra's upper and lower also, sorry about your bad experience on the phone, but have had nothing but great experiences with them on the phone. between nancy and gay I think they go out of to help , like the following.
called them and wanted a matched complete national match lower and a stripped upper and wanted to have the lower sent to me with the the two stage match trigger removed and sent to the gun smith in ill. that was building the upper for me along with the stripped upper and charge the smith seperately for the stripped upper, no problem and it got done correctly,
also have called and wanted to add another complete regular lower to a order that was going out that afternoon and talked to them at 2 in the afternoon their time and they went on pulled my package out of the shipping pile went back to the warehouse and got me another lower and added it to the box and still got it out that day for me.
as far as the triggers yeah I have got a few that were not the greatest on the regular triggers, but just go over to the compitition area on this board if you want to know about their match triggers, (very good )
built a match service rifle last year and by going with the bushmaster lower and then having to ad a decent trigger I was intothe rifle when done $1400 but by going rra's this time it will be at only right at $1300. that extra $100 will buy me a box of 500 77grain smk's and a few pounds of powder.
I know guys that also shoot both and its like they both have a great rap.
