This only fits bull barrels!!!!! - Rock River Arms Varmint Gas Block Assembly

Heath Allen's Review of Rock River Arms Varmint Gas Block Assembly
I purchased this believing the One Size reference was a standard.750 gas block diameter. It was twice that if not larger….maybe a 308 barrel? Optics planet is always on point so I gave the product a 5 star because it is not OPs fault. Hope this saves someone some money.
