Thread: Question on my first AR.

I am getting this for multigun, no other use for it really. I do plan to get a CMMG .22lr upper, that will see more use on it with myself and the boys.

My plan, good or bad was to build based on aero precision upper/lower (price that works), elftmann 3gun trigger (never had an AR but spoilt with the triggers I have had on others) and the rest is up in the air..

I thought I would go with a 16" barrel so that is somewhat matched the .22lr upper that I wanted to use for practise.

For my various research, this is where I am a little lost, the buffer and buffer tube... If I have a 16" it seems that mid length gas might be the way to go based on recoil.

Now, I know that rifle length and carbine length require different buffers and therefore different stocks. While putting together my wishlist I dont know if I am supposed to be looking at carbine or rifle stocks as I don't know if mid length gas fits in one or none of those configurations.

Any hints would be greatly appreciated.

Also, seems that aero uppers are hard to find in stock at the moment while lowers are in stock at a couple of places.

PS, this is all from the mind of a newbie so feel free to be harsh if ideas are very wrong

Thanks!
