Re: wtb: big bore ar upper for 458 socom
So you actually have one of those mystical unicorns????? Lucky. Gunbroker had a stripped RRA upper for sale for a long time. I just checked, ya it's gone. WC has billet uppers instock and there forged uppers should be instock in a few weeks. If your really itchen to get that build put togeather I'd buy a Mega upper and send it to the Gunsmith back east that has been doing the port door mod's for years. If that's something you want to do Ill dig up his phone number.
