I bought an ARsenal Inc AK-47 and 4000 rounds of the cheapest Wolfe ammunition for it that J&G sells.

AFter almost exactly 2200 rounds I finally had to clean something, the trigger.  So much grit has built up that I finally had to put a little lubricant in that area.  Solve the problem immediately.

Wonder if an AR-15 could go as long without cleaning?

The Arsenal Inc guns, incidentally, are the best AK's I've yet seen.  I also noticed that they are adding several more models and even a line of 223's.  I've ordered one of those.

You can pre-order the .223 ones? interesting.  

I'm betting those will be about the lightest recoiling AKs on the planet, what with heavy milled receivers to absorb the already small impulse of the .223.
