Nice Value Upper
Fit and finish is great and I can confirm that this will work with a 450 Bushmaster barrel in case anyone is wondering.
WOW Quality at a "great" price!!!
by Michael -
I received my daily/weekly alerts from Primary Arms and i cant say enough about ,both the quality and prices of all the products they carry at even its regular prices! But boy did i luck out! The total of my bills with shipping "if" it wasnt free shipping was $69.99!!! I ordered it June 26th and it arrived at my house today! ">) Man thats fast i didnt pay for any out of the ordinary shipping and would have to go back into my bill to see if there was even a shipping charge? It was one of their flash sales or was it a secret sale?rofl either way top quality i just love RF and have been wanting to build a 458Socom for some time! All my rifles have dedicated lowers ,none of that 5uppers with one lower! for me! I want one in every caliber an AR comes in! then ill start on AR10s if im still young enough! HAHA Quality and a "Great" price!!! Dont you go changing Primary Arms you guys are almost perfect! Almost.....dont go getting a swelled head! hehehe
