What is the best type of iron sights to use on this pistol?

BEST ANSWER: I would recommend Magpul MBUS flip up sights for a great economical iron sight set up. MBUS Pro sights would be a great step up from those.

Sweet action
Love it! I had been wanting a shorty for a while and came across this beauty. Added an optic, back up iron sights, and a finger stop on a partial rail, turned out super bad ass. 10/10 would recommend.

This thing is AWESOME!!!
I bought this PSA pistol because of the price. I wasn't expecting the great quality. I have been thoroughly impressed. I've fired 300 rounds with NO hiccups. This gun is so much fun to shoot. I put a Sig Romeo red dot on it and I carry it in a briefcase. I will say the 5.56 with a 8.5 inch barrel is LOUD!!! I'm going to purchase a 300 blackout upper so I can add a suppressor. Get one, you won't be sorry.

WOW! Love this thing.
Picked up this tiny AR and there are no regrets. I was worried with 8.5 inch barrel there would be cycling and accuracy issues. I've put about 300 rounds through it so far with no malfunctions. I installed a Vortex Strikefire 2 red dot and sighted it in for 100 yards. No problems hitting the 12 inch steel at that distance every shot. Only negative is the grip, not very comfortable. Will be replacing with Magpul grip.
