RRA LAR-8 gas block question

[snowplow]

Has anyone used an adjustable gas block on these guys? I'm starting to think I'm screwed

I am not familiar with the RRA LAR-8...is there something different about its RRA gas block ?

Any reason a normal Adj. GB wouldn't fit and work ? , without proprietary RRA parts ?

What barrel diameter do you have ? And how much clearance does your handguard have around the GB ?

Am I not understanding something ?.... what issue are you having ?
