My 11 year old step daughter and I will be building an AR rifle with a CMMG 22LR Bravo Conversion Kit. The plan is, once she is comfortable with the rifle we can switch out the BCG. That way, the only major change is the recoil but she will be comfortable with the rifle. While talking to someone familiar with firearms, they suggested using a dedicated 22LR barrel from CMMG. Their reasoning is that would keep the dirty gasses out of the upper receiver.
After I left and thought about it a while, I thought to myself, wouldn't leaving off the gas tube or even the gas block do that as well? Sure, but some gas would still escape through the hole. But if I installed the gas block backwards, it would simply act as a plug for the hole. The rifle will have a free float handguard. I can't really think of a reason to not just put the gas block on backwards. Can anyone think of any legitimate reason this would not work or would be a bad idea?
