| Someone wants to trade me a 20" H bar upper, he claims its DPMS. I'm not sure where he got it from, but he stated the dealer said it was chambered for NATO 5.56 and had a 1/7 twist. There are no markings or writing on the barrel. How can I tell the Twist rate and cartridge size (SAAMI or NATO)? |

fastest way would be to contact DPMS themselves: www.dpmsinc.com/support/contact.aspx i'm not completely sure, but i though DPMS only had 1-9 twists on thier regualar HBARs....but i'm probably wrong |
