AR Carbine VS Mid Length

[kakpataka]

Randall................... so you cant make a hole thingy on a barrel of an existing carbine to make it mid length?

You can drill another hole, but you can't mount another gas block or front sight because the barrel diameter is too small when you move forward to the mid-length gas port position on most barrels.
The exception to this rule would be on bull barrels where you have the option to turn them down to a standard diameter or on CMMG M10 multi-role barrels that have 3 gas block seats.

Bottom line - do what's best for your gun/ammo combination. You can tell what you need by how far the brass is spit.

What do I need when my brass is only flying out like 12" to my 4'clock?

Wow, that's exactly what I was looking for and a lot of information too.

It looks like I would have to get some kind of fancy buffer to go heavier than a rifle buffer.

If they drilled the gas hole to work with an H2 buffer that should be a pretty close match to a rifle buffer so I should be OK. If it's not drilled that big, the ideal buffer weight will be less which should be moving in the right direction and if it doesn't work well I can always enlarge the gas hole a bit.

What about hydraulic buffers, or buffer ends made of different materials that are supposed to soften the impulse? Are these useful in reducing stress in a carbine system, or just snake oil?

more powerful ammo.

snake oil.

What he said.

The entire thread dealt with a single round, heck it could have been talking about a single shot self extractor. Whatever the case, it has been stated and remains true to this day that reliability is like this:

Carbine < Mid-Length < Rifle

So when you can have a rifle length gas system you get that, if you HAD to you'd go to a Mid-Length, than if the length won't allow it you go to a carbine gas system. Than if your really really crazy and want a super shorty than you have to go to the abbreviated gas system. Nowhere does it say that if you CAN have a longer gas system should you go for the shorter.

Haha. u just reminded me that I need to study for my chem midterm.
