Dealer set me up with the last of the parts I needed last night and so today I stuck my 5.5in 9mm SBR AR15 together. I am using Promags at the moment. they work OK. But I am having some FTF on the first few rounds. If you only load 20 rounds they seem to work fairly well. I think I am going to convert some UZI mags to use with it but has anyone had this problem before? I am using a Hahn Dedicated block and a RRA bolt/ upper. |
