Walther ppq q4 tac
The walther ppq q4 tac comes with a ridiculously low front sight I dunno why they did that. It was hard slaving the rmr to the front sight. Thankfully I found this company I ordered the .300"x 125. Shipping was fast and the sight fitted up perfectly to my gun now it will be much easier to line up the red dot with the front sight. Thank you dawson precision.
