I'm going to build my first 9mm, RRA 10.5" upper SBR or course. My question is about the Hahn mag blocks. I'm leaning toward the dedicated 9mm adapter because I have other 5.56 rifles, so I won't be switching back and forth. Are any of the Hahn blocks better than another? Is it worth spending the extra $$$ over the RRA mag block? Steve |
