Ratings & Reviews
Excellent 9mm upper
by Joseph -
This upper is great for the cost. I use this on a standard AR-15 lower paired with the Stern Defense mag well adaptor. I’ve put about 500 rounds so far and had no issues. The tri-lug was the selling point for me. It works great with the Dead Air Ghost-M tri-lug. Ran great using magpul and OEM glock mags. Lastly it functions flawlessly with the BFS-III binary trigger.
<br>The only thing I wish this had was side charging. Standard rear charging is very gassy with blow back style uppers when suppressed. However, un-suppressed there’s no gas in your face.

My product arrived with out a dust cover. A dust cover is clearly shown in the photos. Also the ejection pad is missing.
If you haven’t tried your silencer on a Tri-Lug you’re missing out

If you have a silencer the Tri-Lug is the way to go. I have silencers for threaded barrel pistols in 9 and .45 then ratchet type connections for .308 and 5.56 and thought that was the best because they don’t loosen like the threaded pistols do. Then I bought the Tri-Lug which puts everything else to shame. It simply slides on passed the lugs then you’ll feel tension and turn it a 1/3 twist and it locks in place. The tension is from the internal spring in the silencer which acts like a lock washer keeping the silencer from loosening. It’s the easiest to put on and come off with a positive lock that does not fail. If you’ve read this far you’re like I was and want it. Just buy it and post here next week.
