Tom K from United States, CO Public Profile

I recently purchased this to replace the stock white front sight on my TX-22. What a great difference this makes in the outdoors - that yellow fiber really lights up and makes for a great front sight.
As for the installation, when I first started tightening the little screw, the sight still was loose. I started to tighten the included allen wrench more and the sight started tightening up. A little more and it's rock solid. Bottom line, you will need to really tighten the little screw before it's locked in place.
One comment I'll make for TK is that the oval base that inserts into the pistol frame sight hole could be a little larger to ensure proper alignment.

I ordered the FDE because the black was out of stock. So, first, if you want this to match the rest of your FDE rig, take a picture of it as soon as you get it, because that's the last time it will look like the picture. The FDE paint comes off pretty easy.
Second, but perhaps first, is this is NOT a 10 round mag as it will only hold 9. I can live with that, but it should be advertised as a 9 round mag. Lastly, even with 9 or less rounds, it will bulge a little and is a little tight in the mag well.
The only reason I bought this mag is because the manufacturer of the upper I have recommended them. Based on other reviews, I purchased a couple of 10 round C Product mags and they easily load 10 rounds and feel to be of better quality at the same price. They share the same outer dimensions so not sure why the ASC would only load 9 unless their follower is too big.
That's it. Hope y'all have better results than I did.

I bought the 4 round mag as well as the 7 round mag. Took them out shooting and the last round of the 4 round mag would never cycle correctly - round always dead headed into the breach face of my BCA upper. Never once did it cycle the last round correctly. On the other hand, the 7 round mag cycled flawlessly on all and the last round.
I originally bought the 4 round as it was fairly flush and didn't want a longer mag when bench resting. However, the 7 round mag is only maybe two inches longer so no problems bench resting. I am returning the 4 round mag and will get a couple more of the 7s.
