Well, I returned my exceptionally worn underfolder to CFS for an exchange, and the replacement just arrived. WOW!!! It has minor surface wear and that's it. The barrel has absolutely no frost or pitting, an absolute jewel of a crown, and the interior of the gas block looks new. The folder locks up rock solid. No wear on the gas piston, bolt or carrier. No scratches on the pistol grip. All matching parts. And a standard trunion to boot. The kit is undated, and there are a few scratches in the wood. This was well worth the price of return shipping. Sorry, no pics, but other threads have posted pics of similar kits. This will make a sweet rifle... Let's hope the RPK kit I'm waiting on comes closer to this kit than it's predecessor.
