Had a set of cheap magpul knockoffs on this AR they would not fold flat and partially blocked the view through my Red Dot. The HK/PRI sights were the rememdy. They fold flat and are 1.5" in height so they co witnessed perfect with my red dot. Sighted in easy and the was surprised at the accuracy at 25 and 50 yds. Got them when they were on sale for 19.99 but I would definitely pay the $33 they are listed for now. Compared to magpul composite sights I would take these everyday.

Solid iron sights I wanted to put on iron sights on my build. I saw this on ACME. I think the HK style would look very nice on my pistol. It look great and it works great. It is straight forward and does its job. The price was excellent. But the quality of this and the other items I have purchased from ACME is what consistently bring me back. This is an excellent company and their products are top notch.

Compromise Sights I bought these for a beater rifle I have. This thing gets used as a tool. In the woods, banging on trees, I put thousands of rounds through it and it gets hot. That being said... I put it together with the cheapest parts I could buy to see if spending big $$$ was worth it. Well it’s not... cheap parts send lead down range very well. These sights completed my joe dirt build. Kind of sad that they are “MADE IN CHINA” as they are the only part of my gun that’s made in China. Everything else is AMERICANIESE BABY. If you need these for a battle rifle look elsewhere, if you need a super expensive gun so you can be part of the metoo expensive AR movement then look elsewhere, if you need a clear and cheap sight picture for a gun that you use as a ranch rifle or tool for popping the heads off of gophers on your property while you slam your gun in your floor then this will Work fine. 4stars for Chinese manufacturing

Nice sights Solid construction. Good sight picture. If I were to do another build, I would definitely order these again.

Quick sight acquisition I have used type of HK sight in the past on a few builds and these are just as good as the others. I like the quick target acquisition from the front sight. One thing I do is change out the screws with a hardened set from Ace hardware and these not only look better but have less chance of ever stripping out. For two more bucks it’s well worth it. These appear to look like they will wear well for some time. Not a bad set of back ups.
