I'm looking into starting my AR build And I got most of it figured out except... I hear all this talk about a gas piston setup/conversion. Whats the benefits of a gas piston instead of the standard setup? I know my SKS has a gas piston and it works flawlessly, although after extended firing the handgaurd where the piston is gets extremely hot. Will an AR with a piston setup heat up like this as well?

Benefits? They are great for short barreled carbines but for the most part they just make you feel good. Most of those kits are junk, the good ones will do the same thing a $10 gas tube will do.

So I should stop worrying about it and build the damn thing already?

Yes :)

If you can't honestly answer this question "Why do you need/want a gas piston?" with a smart answer to justify the $400 added expense, you shouldn't buy one.

Agreed. If you are looking to build a weekend range rifle, bypass the piston setup and keep your rifle clean. If you plan on going into combat and getting into "lengthy" firefights, I would say get a GOOD piton rifle. Just my $.02.

Because when you go into combat get yourself a heavier, more complex, more expensive, more moving parts to fail, unproven system. :rolleyes:

I dont plan on getting into a combat situation unless the sand monkeys decide to invade. IF that happens, a couple hundred bucks for an upgrade might be an option.

wow, there are tons of threads on this subject so if you search you will find all the info you want and then some,lol. I dont even want to touch this subject again, but I have built and fired both gas piston and DI AR15s and while the piston system worked fine, so did my DI system. As to real life combat situations, my DI M16a4 had numberous malfunctions, and once I had to transition to a different weapon due to a malfuction that could not be cleared, however I believe that the same malfunctions would have occured even with a gas piston system, unless that gas piston system was an AK47 lol. GPUs are best used for fully automatic weapons, especially short barreled variants, and for suppressed weapons.
