Im gonna try and trade my extra 18" upper for a pistol... I only have my p80 g19 right now for pistols.

Can pick up an M&P9 single stack for under $400 and have $200 for ammo...

Single stack 9?

MN requires a permit to buy handguns or "scary assault rifles". I'm not complying with that shit. Luckily shotguns only need the regular NICS check. Building a gun isn't regulated here either.

Ah

So a polymer 80 then?

Yep. It's looking like that'll be what I get. I originally wanted to build an 80% Sig P320, but that's a few hundred more.

Yeah, @Bogs_Bunny I think you would be better served with a reliable handgun

Question to all you gurus from someone who is still learning.

what do you think I should upgrade on here?

So if you dont have enough gas going from your gas block it wont eject and cause a malfunction.

What happens if you have too much?

increased wear, case head separation possibly

which is an absolute bitch

more recoil

but also more reliable, if you dont overgas it too much

^

Your extractor probably won’t like it

Cam pin definitely won’t

So essentially you want just enough gas for ejection and everything else to work properly and no more.

Gas rings will wear quicker

That’s basically exactly what you want

a little more than necessary for when its dirty

Just enough to cycle reliably

But not removing finish on the brass deflector

Gotcha.

Also what's a BCG and FCG.

bolt carrier groupo and fire control group

Over gassing doesn’t increase reliability, you just get increased parts wear and *different* malfunctions

Also @squidsoup0 id get a sling

And a WML

Ive got a steiner battlelight mk4 its just on a different ar right now. Youre definitely right on the sling though lol

I made this one from paracord because I only had one sling and like 7 rifles

Slightly overgassing allows your rifle to power through some grime, and cycle shitty underpowered ammunition. It's generally better to be slightly overgassed than undergassed, but the best way to do it is get an adjustable gas block and set it correctly.

There are little bandaids for over and under gassing, such as buffers and spring changes

See, but that’s based on the idea that a rifle can’t just...be correctly gassed.

Between an H buffer and an H3 buffer (if you buy both) you can make any weight combination available.

@Crye_Salesman

I’m aware. I simply said it’s a bandaid for a rifle that is not properly gassed.

Yeah that was directed at confused

I gotcha.

I agree with your statements above. Any overgassing is just extra wear and tear on the parts. Over-gassing leads to increased wear on the gas-rings, causing them to have leakage faster, and to be inefficient.
