Can I change barrels on an Ar pistol? To a different platform. Like a longer barrel
Rusty on Jun 26, 2019
BEST ANSWER: Yes, you may start with an AR pistol and put a rifle length barrel on it. Depending on the state and overall length it may or may not still be a pistol. Under current BATFE rules if you start with a pistol you can convert the pistol to a rifle and back to a pistol but you cannot start with a rifle and convert it to a pistol.

Best pistol brace as of 2019
Huge improvement vs sba3 imo. Stiffer. Longer etc.

What I wished the original SB4 was.
First off, never buy an SB brace in FDE, the original style SB4 I got (one without the angled pieces that add support to the bottom of the rear vertical) didn't match any of the FDE stuff at all. That's what led me to want to try this. I got a good deal on this and I had to try it and boy am I happy I did. It has the extra support to the bottom of the rear piece for when you're "incorrectly" using your brace and it's a touch heavier which adds better balance to my 10.5" pistol and it's black so it doesn't have to match the rest of the FDE stuff. Win-Win-Win. I got it for 90 on-sale which is ok. I paid 130 or so for the original SB4 which is way overpriced for what these are.

Best pistol brace out currently.
This brace is a phenomenal improvement from the SBA3. The new rubber shielding around the release lever adds much more stability and it is rock solid. I will be purchasing another. If you are thinking about buying one, do it.

Good Item.
Just installed this on my Palmetto AR pistol. Its tight on the tube and hopefully with a little lube and use it will break in. Installed very easily.
