    I wasn't sure how this was going to look on my 13.7 AR Pistol. I needed something longer to pin and weld, (Thank you AFT) and found this. I honestly thought it was going to look and feel cheap because of the low price. I was very surprised to find the quality and fit to be very high quality. Looking forward to seeing what else KAK Industries sells now.
