I'm shopping for a new AR and I'm looking at LMTs (BCM is not taking new orders atm), but I was wondering if it is worth the extra cost to get the gas piston version over the direct impingement?
I've heard that piston versions won't get as dirty as fast or require cleaning as much in order to actually shoot. I've also heard it reduces recoil for faster follow-up shots...

Thoughts? Opinions on this?

Thanks Dogs!
