Re: SBR?
On a side note, consider going with a 14.5 incher and a pinned mount/flashhider. I've got a SBR lower, and have gone to the 14.5 because I didn't like having to keep track of paperwork and never leave the SBR hanging in my wife's truck. Couldn't loan it out, etc. Of course, mine was a 12.7, with a mount on top of that - so I wasn't but a couple inches shorter than a pinned 14.5. If you are going shorter than 12.7, then it might be worth it to you. I do kinda miss my shorty at times, but it's nice not to have to keep track of where it is all the time. Noveske's little pinned 13.7 rig calls my name at night, too. Short is fun, but make sure it's worth it to you. I tend to want to sink stamp money into suppressors.
