The One Gun Solution (GP Carbine) - Reality?

[Failure2Stop]

My go-to is either a 14.5 with a short can, or an 11.5 with a larger can.
Both with an LPVO, light, and IR laser/flood.
I have gone past 1k with the 14.5 and purpose-oriented ammo.
The overall length and weight of both is very similar.
The 11.5 shines indoors due to the more effective suppressor, while the 14.5 takes over once past pistol-caliber range.

Ah, the quest for the unobtainable.

I'm more of a 11.5" because if you are going short, go short & 14.5/16" because you gain a lot with those inches.

I have all 3 but I'm not gonna start selling because of internet gymnastics.

My 16" LMT with the Steiner PXi 1X4 & Inforce 800 lumen light fills the bill for me.
I am going to switch to 69gr. IMI for standard HD/SHTF soon as I can get stocked up enough.
I have only limited experience with the shorty AR's, and Lord knows Im no "pipehitter" either..but to me, FOR me, I love a 16" gun.

Right, I’m not saying you should sell anything either. This is just discussing my take on a true “do all” rifle. Meaning it is the ONE you would pick, if you had to, that you’ve set up to handle all realistic engagement scenarios within 400yds at day or night.

ETA: Maybe shooting under NODs isn’t even part of the consideration for some, but I would like that capability and that’s where the wrench gets thrown into my “do all” day gun...how do you take that same gun and make it work well at night?

A member on TOS did some interesting testing a couple years back with 10.5/11.5/12.5/14.5/16. With velocity you gain very little going from 10.5-11.5, there is a rather large jump in velocity going from 11.5-12.5 and very little increase going from 12.5-14.5, some increase going to 16. This was load dependent of course, 5.56 FMJ seemed to have some benefit going from 12.5-14.5, everything else gained little or nothing.

I know you use the IR laser for aiming at night under NODs, but when you have to go IR to vis spectrum quickly, how do handle the LPVO in that situation? My understanding is that’s where an RDS works well in comparison since you don’t have the eye relief limitations. Keep in mind I’ve had about a 4 hr block of instruction on NODs from Pressburg and that’s the extent of my knowledge other than reading things here and there.

And back more on topic, which do you pick for the 0-400 parameters in the OP if you had to just pick one?

LPVOs and NODS don't play together very well.
If the NODs drop down, I'm 100% on laser or gross aiming technique. If the laser doesn't work and it's dark, I'm on light + LPVO for GP carbines.

For the 0-400 range the practical reality is that an 11.5" 5.56 with effective suppressor is going to leave very little on the table.

Thanks, that all makes sense. What’s your go to LPVO these days?

[MegademiC]

How well do offset rds work with nods?
Could you skip a laser or still need that option?

I dont run nvg yet, but I like a mini suppressor (socom mini556) on an 11.5. Its just quiet enough and saves significant weight/length. 12.5” would be fine as well. Id rather have more barrel length than silencer length, but again, nvg might change that.

Take whatever AR you have, put Ultradyne irons on it (easily move from 0 to 400 yards), and adjustable white light for no light, and maybe a visible laser for low light. Or you can scrap you rifle, spend thousands and thousands of dollars on short barrels, Aimpoints, night vision and IR lasers.
