as long as there isnt a raised comb on the stock it should be the same as ar15 the prs is ar10 specific because the ar15 comb will interfere with the charging handle the monolithic uppers are not really any heavier than a billet upper and a aluminum quad rail if you want something a little lighter but still rock solid i recommend the pri float tube either round or delta tube they are pretty light and as long as you don't need 4 linear feet of rail they are rock solid tube also if your going to pay for the ultramatch from ranier i would look at the noveske barrels
