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.

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.

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.

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.

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.

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.

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.

Saw his pop on YouTube. Seemed appropriate.
