Sorry for being off topic. But since there is some conversation about AKs and ARs. What do you think of the PWS rifles and there operating system. But back on topic. Back in the early 90s I shot a lot of competition IPSC. Most of the failures I saw were guys who jumped to modify their pistol every time the latest and greatest item appeared. I have always bought the best I could get and then just shot it. Never have tinkered. I always figured good manufacturers and smiths new a lot more than me. I have never had a mechanical failure from any of my guns. I have a Para P16 that cost me $2500 to have built in 1992 that has over 50000 rods through and have only changed springs in it over the years. It has never failed. If the majority of people would put their money in ammo and practice they would find that is what improves their skills. Not the latest fad.
