What length barrel are you shooting the IMI ammo?

It is a 16" 8 twist

I’ve had good luck with 62 Gr bonded and 75 Gr BTHP. 77s did ok, but not as good IMO. My got to has been the 75 BTHP for the past 3 years, and lots of pigs have died to it. I run them in a 17” 8 twist.

We kill tons of pigs with the cheap 7.62x39..
Run duramags and have 0 feeding issues

With a 8 twist you could certainly try heavier bullets before you buy another upper. That being said, if you get a grendel you'll never regret it.

You can’t beat a .450 Bushmaster inside of 250 yards

Another vote for 6.5 Grendel. You could also use 69 or 75 gr rounds with your current set up for something a little beefier. Not the biggest fan of 300 Blk.

You’ll need barrel, BCG, and mags.

There's been 2 mentions of just a barrel swap. That's not the way to go. Get a complete upper with bcg and your good. Barrel swap is a good bit more complicated and then you won't have a .556 anymore.

Definitely more complicated than a complete upper swap, but not difficult.
Did op get rid of the rock river with the 24” barrel?

How is more complicated than a complete upper swap?
What am I missing?
I've only swapped barrels & bolts more than once, and have had 0 issues.

458 socom will hammer hogs,, 300 gr hp at about 1800-1900 fps,,,, there is never any doubt if you hit the target and blood trails if they are needed ( rarely needed) are massive ! kinda thinking about selling my upper with ammo, just not sure if i want too!

5.56

this was just the feedback i was looking for.. since brass is scarce, and i have plenty of 5.56 brass/pwder/primers, i'll first reload some 70 speer, and 75 bthp i have. i have two ar's 1:8, so that will be easy. i'll def. be looking for some grendel stuff in the future. sportsmans guide has a couple uppers, now. popped a couple last monday w ear shots.

i still have the rra varmint a4....it's not for sale.. but it is crazy accurate..with anything you shoot through it. only drawback, it's an 11lb'er

An upper and BCG swap takes 30 seconds... if you’re slow.

Also swapping barrels you have to change out your optics and rezero. Swapping uppers, you can keep your optics zerod

10-4, I didn't realize those things were considered complicated.
When someone says barrel swap, I have always assumed those things were taken for granted.
