18” vs 16” barrel with midlength gas system

[LRRPF52]

If you think about the suppressor as an extra few inches of barrel, it helps you configure the gas system you intend to use.

I still haven’t even attempted to mount mine on any of my MLGS 18” rifles in any caliber.

For 6.5 Grendel, I have kept my 5” Ultra 5 on my 12” Grendel, and use a Bootleg Adjustable Carrier to choke the shaft between the carrier key and the expansion chamber.

16” MLGS is better to suppress than 18” MLGS because 18” already has more plug dwell time.

18” ILGS or RLGS is a better way to go if you want 18” suppressed. The farther forward the gas port is, the better for a suppressed configuration.

Any Grendel barrel length will deliver good results out to 600yds in my experience. That distance is mostly child’s play, unless you’re chasing 1 MOA targets (6” at 600yds, tiny).

I’m at higher altitude, so I get away with shorter barrels and don’t see a noticeable difference between 12”, 16”, and 18” Grendels.

It’s just a dial or holdover and windage hold for me.
