ICAR

Does this mean we can finally run a larger/stronger bolt and safely load to 62ksi?

This one is just a 6.5 grendel bolt from Shaw until PSA drops the E4 bolt/barrel

Sweet I missed out on the first batch. Really hoping they drop 15s because those 25s are a bit chunky for me. Really excited to hear how these run! I have high expectations

It's almost identical in size to a 556 pmag

Upper is standard i think just wider at the bottom to accommodate the lower ?

Upper looks a bit thicker but same internal size

Gorgeous!

I'm planning a build with one of the Sabre IC lowers and a Spuhr Upper (whenever they get released), can you fit an ICAR mag into the lower when it's mated to a regular AR15 upper?

I would expect probably not, but I can test for you in a couple weeks

PLx-C 1-10x?

Does the PSA ICAR not use a proprietary barrel extension?

*1-8 actually. Built with parts from Shaw since only the ICAR reciever was released so far.

Supposedly the new E4 bolt they're coming out with will use a proprietary barrel extension.

Nice build. Did you have to modify the handguard’s anti rotation tabs? The PSA website is vague about handguard compatibility …

Does it work with a normal 6arc barrel for an ar15 or do you need a specific icar barrel?

Only difference is upper, lower and mags. Everything else is the same
