"Arrived in a few days, along with the other goodies I ordered from CTD. It slid home in my new Del-Ton AR-15 like it was meant to be there. Now, for the real test..."

"Before i bought 2 of these KNS perma pins i read several bad reviews and it worried me. I went ahead and bought 2 of them anyway and I'm extremely happy with my decision. These are high quality and work perfectly in my Matrix Aerospace custom AR!! At first it was a tight fit but if you just take it easy and put them in slowly and correctly you really can't go wrong. Don't hesitate to buy these. I will use KNS perma pins on all my future AR builds."

"Great product slid in just like it was suppose to much better than the factory cotter pin. I would recommend anybody with a AR style rifle to get one of these."
