I love my middy 14.7" PSA . It even cycles perfectly with the .22lr kit in it which is great for practicing with . This is my go to gun next to the PSA 16" red headed step child that has more than proven its self with well over 8000 rds now without any issues other than the cleaning and new gas rings it got over the winter that I thought it needed . I hate to deprive a gun but this one really does get the most attention out of all of them , She gets more range time and more hands on her than anything else I own

Just something to think about.

Direct impingement is actual a piston system with the piston being on top of the bolt carrier and super short.

Jon is right the piston system is just puking gas under the hand guard instead of in the upper like a DI system

Sounded better keeping the inside important part away from the fouling and heat.I heard they can pose the problem of shaving some metal slowly on the inside

AR is designed to be a D.I. System, and works well in that format. It is NOT designed as a long/short stroke piston system.

Would you convert your AK to a D.I. gas system?

If you want a piston gun buy a AK , if u want a AR go DI. Pretty simple choice really , they are both proven , parts galore , and both very reliable in their original form. Im not saying a piston system in a AR is bad but if something breaks on a piston AR, chances are your not going to stop into just any shop and get parts and who wants to wait to have fun

Kryptar and purehavoc points just convinced me. I was always tempted to get that PWS Diablo upper for quiet long. But now that temptation just been reduced to be 30%.

We should start a "How can I convert my AK to a DI gas set up?" On the AK forum?

No shavings to speak of. There is plenty of room for fouling to go and get out of the way. DI does blow some stuff into the upper, but it does not cause any problems. I have never seen an AR malf from fouling. I have seen AR's malf from lack of lube. The gasses will contribute to the lube drying out. Lube it up and go
