Works as intended

Ordered this after shooting my AR9 with a supressor the first time. As a left handed shooter, I was getting peppered with unburned powder. This product massively cut down on the amount of blow back gas and debris. Good product at a fair price. Only con is I had to do some fitting on the deflector. The hole the pivot pin passes through was not parallel to the axis of the hole on my upper receiver. Some sandpaper and patience took care of that issue.

9mm Build

I used this kit for a 9mm build, it fit good and is great for the build, I would buy again.

Not enough info.

Not sure how the gas deflector is supposed to fit. Initially it kinda flopped around. There is NO apparent way to secure the top of it to the upper. That somewhat defeats the purpose of having it. It's only for a dedicated 22 though, and the upper is just polymer, so super glue to the rescue. This would definitely NOT work for a larger pistol caliber. Good thing it wasn't expensive.
