Never thought I would want one, but a friend just built a .556 pistol. It is a pretty sharp build, IMO. I cannot afford a Sig, but have been looking at PSA and some of the kits they offer. Specifically a sba4 brace, 10.5" barrel. Right now, I have no intention of a can, but my friends all tell me that will change. I doubt it, but like I said, I never thought I would be considering an AR pistol. I appreciate any feedback the brain trust here has to offer.This message has been edited.

FWIW, I have a SIG MCX in 300 Blackout, and firmly believe that such pistols (or SBRs) are most logical reason to have a gun chambered for the cartridge, and that having such a gun can fill an important operational niche. “I can’t give you brains, but I can give you a diploma.” — The Wizard of Oz This life is a drill.

My PSA kit has been totally reliable and fun. It sounds like a nail gun, with the can on it. Seriously, pulling the charging handle and chambering a round seems louder. Go for it. Bruce "The designer of the gun had clearly not been instructed to beat about the bush. 'Make it evil,' he'd been told. 'Make it totally clear that this gun has a right end and a wrong end. Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with." -Douglas Adams “It is just as difficult and dangerous to try to free a people that wants to remain servile as it is to try to enslave a people that wants to remain free." -Niccolo Machiavelli The trouble with fighting for human freedom is that one spends most of one's time defending scoundrels. For it is against scoundrels that oppressive laws are first aimed, and oppression must be stopped at the beginning if it is to be stopped at all. -Mencken | |||

For real? |
I’d like a SIG Rattler in 300blk but for now my PSA 7.5” (pistol) and 8.5” (sbr) have been running fine. Suppressed and unsuppressed. Here’s my pistol with Sandman-K. PSA upper and lower.  Not minority enough! | |||

I love 300 BO. My SBR wears its Blackout upper more than any other despite having a 5.56 and a .22 upper for it also. I have a 762SDN6 on it and run subs through it. I also have a Rattler that I use supers unsuppressed. I don’t think I’ve ever jumped on a new caliber as quick as I did 300 and I don’t regret it at all. | |||

Ok, My upper has arrived. 10.5" with the flash can. I have ordered a lower with the sba4 brace. Now I am looking at optics, but know very little about them. Is the Vortex Venom Red Dot 3MOA a decent optic for this type of pistol? Probably nothing out to more than 100 yards. I have the MBUS that came with the upper. Will I have to remove them to use the Vortex Venom? Thank you for your help, this type of pistol is all new to me. Niech Zyje P-220 Steve | |||

I'm sure you can use the Vortex Venom on your 300blk. I have one on a Ruger Mark IV and it's been working well so far, albeit it's a .22lr. Like Chowser it seems, I have a Romeo 5 red dot on my 8" 300blk build and it's worked great and the motion activation is a plus. Got mine on sale at my LGS for $99. You can probably get it at that price around Black Friday weekend. Sig P229R 9mm - Sig P365 NRA Sig P320C 9mm - Sig P320 FS .40 | |||

I have a Viper on a handgun, it's similar to the Venom. I found it too small on an AR pistol. I think PSA sometimes has the Romeo 5 and Magpul MBUS on sale for $150. Check Black Friday sales. | |||

I prefer the Trijicon RMR on my 300blk pistol. The dual illuminated model on this gun now wears a LED model. If looking to save some money, I would recommend the Holosun Red Dots that come with the proper height mounts to use on your AR15. Put the optic forward on the rail, and keep your Magpul sights on the gun. You will be able to use your sights through the optic should it go down for any reason.   | |||

I have astigmatism and the red dots are too fuzzy for me so I have a Vortex Spitfire prism on my 300 BO pistol. It may be a little larger optic than you are looking for but it works well for me. | |||

Thank you for all your replies. I now have the upper and lower, I plan to put them together later this evening. Do any of you use a buffer (accu-wedge) in your AR pistol? Are all buffers created equally, or are some better than others? I have talked to a few people who swear I will suppress it. I said "i doubt it". But like I said earlier, I never thought I would want an AR pistol, but here I am. Niech Zyje P-220 Steve | |||

Is an open red dot the right optic for this application? While this gun legally a pistol, this is not a handgun. It's significantly bigger than a "real" pistol. It could accommodate something a little bigger. Maybe a closed tube red dot? In the Vortex line, the Spac or Strikefire. The tininess of the open red dots is not necessary. And a closed tube red dot would likely be a bit more robust, and not as likely to get blocked up by crud. | |||

It is coming along nicely. I purchased 5-20 round Lancer (smoked) mags. Any known issues with Lancer? My options for 20 round .300 Blackout mags was pretty limited. Also, any recommendations for a sling? I have the Sba4 brace. Thank you. Niech Zyje P-220 Steve | |||

What optic did you end up with, the Venom? | |||

No, I sent the Venom back and ordered the Vortex Strikefire 2. The Trijicon and Aimpoint were just a little more than I wanted to spend at this point. Niech Zyje P-220 Steve | |||
