Hi: I would like to know, if I cut my barrel to 10.5" or 12", do I have to modify the gas system so it can cycle properly?, or just cut it and keep going? Appreciate any help on this matter!!!!!!!!!!!!!!!!!!!




PD: sorry about my english writing (I'm from Puerto Rico (USA)

Check bogdog's thread for how he did a 10.5" barrel. I'd stick with the standard gas port on the 12" barrel and sneak my up to the proper diameter. I've seen a couple folks here and there that have over-gassed rifles with a 12" barrel.

You guys have to do the tax stamp thing down in Puerto Rico too? Never really thought about it 'til now.

I honestly really don't know much about the stamp topic on SBR's, but here a lot of people have them, I think everybody do the cutting once they got them.

Thanks for the info (link) of the gas system.

good luck sir, if you drill the gas block get a cobalt drill bit, and hardened steel taps, i'm not sure about the right size gas port so i just did it that way
