Had the chance to pick up a NIB Sig Rattler Lt with the 6.75” barrel

Have yet to shoot it, what’s the good, bad and ugly for this AR pistol?

Anything to watch for or expect problem wise?

Buffer weight is important
I like to have few different weight buffers when tuning and sighting in,,but thats an AR thing as much as pistol thing
Just like tuning your AR rifle but little more buffer weight sensitive in my opinon of course
Depending on if your shooting suppressed or not,,it is 300blk so assuming your going suppressed picking the right load and sticking to it has worked for me
When tryn to shoot different bullet weights and supers vs sub loads ive found suppressed if i tune around a specific load and stick to what works your good to go,supers are usually less finicky either way,,,unless you like playing with your gas adjustments i try to buy bulk of what i like and build another gun for a different load😎🤣
Id look into a Rifle speed set up it’s definitely the way to go nowdays on pistol builds,,,,here again in my opinon
Anyway playing tuning and shooting is the fun part!

It should shoot great. The Rattler is a great 300 BO platform.

The Rattler don't use a traditional buffer system!

Plus, it already has an adjustable gas block.

@Shrike99

If you don't mind me asking...what did you give for it?  I have a NIB OG 5" that I've been thinking about offloading to fund other projects.
