TROS 5" 3-lug barrel, everything else is just parts!

Dustin that's what I've Been looking at but what if I don't sbr it and get a suppressor for awhile? It'll be in pistol configuration for awhile. What handguard would u get? Is it like with a 5" you'd suppress it but itlf it would be years before you suppressed it go with 10" with 10" rail?

I ran the 5" barrel and 7" rail for several months until I got my can. You don't want to get your hand in front of the muzzle on the rail, but behind it there were no issues. I don't think it was dangerous in front though. It felt like a big puff of air with sand in it hitting your hand. No burning just startling. I installed the VFG in the position shown in my pics and I use it properly so my hand is always behind the muzzle. I shot the practical rifle match a few times at Oil Capitol in Tulsa without the can. It ran just fine. It did get some junk on the inside of the rail that I can't clean, but it isn't bad and you can't see it anyway.

I would rather get the 5" barrel and a 4" rail or tube made for a pistol if you don't plan on a suppressor for a few years. That way you'll be behind the muzzle and you can swap it later when you get the can. The 3-lug barrel with an MP5 flash hider on it with a 4" rail also looks pretty good.

Those AR's with 9mm mags, for some reason, make me think of a fat person on stilts

It did look a little goofy with the barrel hidden my the rail though.

What is the shortest barrel one can put on an AR with a butt stock, without having to get a tax stamp? 14" or something?

 

[bink98xcab]

16"..

Neither - .50 Beo

But among those, definitely the 9mm.

Did someone say 9mm AR SBR?

9mm SBR'd ARs are flippin sexy.

That should answer your question.

What do you guys think? I've got a few 5.56 ar-15's....

The best way to answer this question would be for you to shoot both and get a feel for them. I'm fortunate to have one of each and would be happy to bring them out for you to try. Dustin was very helpfull when I built my 9mm as well.

I don't have Dustin's photography skills but my gun is way sexier... lol...
