14.5” .308 worth it?

[Kennn]

Is it worth using 308 with a suppressor in a barrel that short or should I just use a 16” barrel. I notice that the military uses 5.56 in an SBR configuration but I also want to reach out a little farther than they can, like up to 600 yards. I also want the extra power the 308 yields but I don’t want to negate that but cutting the barrel short either.

I’m trying to decide between the SR-25 14.5” ACC and the 16” APC. ATACR 1-8 and offset Aimpoint T-2, light, and suppressor. I am just larping as I do not plan on going to war, ever, but if you must, which gun would you take to war and what suppressor?

Will this be for straight-up LARPing or part of your home defense system?

What is the best home defense or CQB offensive gun?

I presume it is a suppressed SBR. Is it a 300 blackout gun or something more powerful like a 308? If so, which? The DDM4 V7P seems great, but possibly the barrel is too long at 10.3”? What suppressor, short or long? For attachments, I would prefer an EXPS3-0, Cloud Rein 3.0, flip up irons, and...

Larping. I like very short for home defense

Larping.

This level of self awareness is refreshing…

You’re talking about 35-40 FPS difference in muzzle velocity.

Take whatever bullet you plan to shoot and look up the minimum velocity for it to expand or fragment or do whatever it’s designed to do. Then get your ballistic calculator and plug in a reasonable MV for a 14.5” or 16” barrel and then see what range that minimum velocity number corresponds to, now add or subtract 40fps and run it again.

I think you’ll see you’re splitting hairs. If the intent is to run suppressed most/ all of the time I’d take the shorter rifle 100% of the time in this scenario.

This, so long as the can is rated for the cartridge and rifle length.

Would you still take the 14.5 over the 16 if I dimpled the 16?

No, then I’d take the 16” because dimples look cool af. Even if it only saves about 2oz.

 

[hlee]

If you are 100% going to shoot the barrel out, dimple it if you want. But, if you think you might EVER sell the rifle, don’t do anything to the barrel other that shoot it.

Hybrid COA: 16" with direct thread can. Lighter and shorter than a pin and weld 14.5 with some sort of 6oz , 2.3" muzzle device and 8oz suppressor adapter.
