Am in the process of purchasing a proof research barrel (steel) for my RPR in 5.56, strangely enough the proof RPR .223 wylde come threaded 5/8 x 24. Does anyone out there makes a muzzle brake in this configuration? Have any of you guys seen them? Now this barreled is being purchased at OpticsPlanet, seems like they’re the only one that have this particular barrel in stock.
thanks
