Jb03 Posted July 5, 2021 Report Share Posted July 5, 2021 Hi all, New member here, finally putting a rifle together off of an Aero M5 set I’ve had sitting around for a while. Got my 18” criterion .308 barrel in the mail last week, running a hi-speed national match trigger. Only needing a hand guard and stock to complete. Planning on trying out the new prs lite if it actually gets released out into the wild any time in the near future. Stuck on either running an Atlas hand guard or an SLR. I’ve used SLR Solos on several small frame builds and have been happy but no experience with the aero M5 handguards if anyone has used both and has an opinion. If all things equal maybe the atlas will look a bit more seamless on that upper? Otherwise thanks for having me, I’m usually over on the SH forum but less and less these days.

What gas system on that barrel, and what's the gas block journal size? It's a Criterion, so it's almost guaranteed to be good to go, but double check the gas port diameter.

Rifle length, .750 I was planning on running a non- adj block but have a spare superlative just in case it needs some adjustments to fine tune. It will almost always be run with a Dead Air Nomad. Also have a JP silent capture buffer system I’m using in it. Quote Link to comment Share on other sites More sharing options...

Also have a JP silent capture buffer system I’m using in it. Gas port diameter for that barrel will be 0.093"~0.096". Double check the JP Silent thing, and make sure it's the equivalent of a 5.4oz buffer. Quote Link to comment Share on other sites More sharing options...
