I have looked around...so if I am repeating questions.....sorry.
I need to remove the barrel nut to install a free float rail. Before I buy more tools I want to confirm some assumptions. What upper vice is compatible with a CMMG upper or easiest to use? 1. Brownells / Bushmaster clamp style - I assume the dust cover has to be removed to use with a clamp style vice block. Does the gas deflector come off separately or does the entire dust cover need to be removed? I also assume the internal block cylinder will not fully insert without the dust cover removed due to the interference with the duct cover pin housing as a result of the barrel set back into the receiver.. 2. DPMS style - Does the block fit into the upper or does the barrel interfere because it is set back into the upper receiver? Thanks for any advice. |

I use the clam shell type action block. I did have to dremel a section out for the shell deflector. Took about five minutes. You will also need to drill a 1/2" hole in the end of the receiver insert.
Tools are the same as any other AR and cutting the block did not affect use with a standard receiver. Dave N |

Can you clarrify the need for drilling the hole or is it so easy I'll figure it out. |
