American Tactical Imports AR15 9MM 5.5 KM ALUM 17 - 32 Rounds

The 1st ATI That was shipped had a broken buffer tube. Had to send it back. The second ATI I got, the safety doesn’t have a good crisp lock and free rotates in a circle. Another bad ATI. I have needed up putting about 1000 rounds through the weapon and it jams all the time. I clean the gun in between range days and make sure the bolt is not dry. Have tried different cleaning products, ammo and even buffer spring and no luck. I would definitely not recommend this weapon.

Super fun to shoot and customize. Well worth the purchase price

I had issues with it double feeding. I used a variety of magazines, including factory Glock mags and on multiple occasions it would try to feed a new round before the old case was ejected. It wasn't a constant issue but enough to be annoying. While cleaning it immediately after shooting, I noticed a gouged out mark on the bolt. I told the manufacturer and they suggested I send it in for repairs. The trigger is also pretty nasty. I hope to get it all taken care of but looking back, I should have ordered PSA upper and lower for about the same price. Decent gun for the money considering what it is, but not great.

This thing just works. Eats every kind of ammo I feed it. Steel cased worked fine. No problems shooting suppressed, either. Barrel is 1/2x36 thread. Something to note, the keymod rail is slim and the barrel does not protrude from it. So any suppressor will need to fit inside. If your suppressor has a 1.35" OD, like an SDTA B tube, you'll be fine. It will fit. Mine fit fine. If it is any larger, it won't fit under the rail and you will have to either switch out the rail, cut 2 inches off the rail, or take the rail to a machine shop to have it widened. Highly recommend.

First, a big two-thumbs up for Buds as usual. There haven't been many reviews on this AR15 type 9mm "pistol". I've been wanting a Glock magazine capable PCC or pistol and this just looked pretty solid. Well, this has been an incredibly positive purchase. Fit and finish on the ATI is superb; this is really well done. As expected, very similar AR15 controls. Glock magazine (OEM, ETS and Magpul) all function just fine, but they do need a solid slap to seat fully. The magazine release is a little stiff and requires concerted effort. Trigger is typical but still decent. I did add the Shockwave arm brace, Magpul BUIS sights and a Holosun RDS for co-witness. This makes for a very functional "pistol". I did run into run problem and that was adding a Mapgul AFG. The flash suppressor has a pretty large diameter and most Keymod rails won't attach...it took a few attempts to find the right size. Additionally, I've heard the rail diameter is also just slightly too small for most suppressors; something to be aware of. Lastly, the only negative is that there is no "last-shot bolt hold-open". This was a disappointment, but knowing the cost to have one on other rifles, it's not too hard to adapt. Overall, I'm very impressed and this was one of my best purchase of 2017 so far!
