Just got done running a 2-Day Long Range course and had the opportunity to test-fire and extend the range on this little pistol out to 800yds.
I was anticipating cycling issues since I'm in new territory with the Maxim PDW brace, mini buffer, and this barrel combo with CLGS, but it was flawless.
I tested first round hold-open with one round of 123gr American Gunner, locked back beautifully.
Then went through a mag while field-zeroing/holding at 200yds. Everything ran fine, ejection is very positive at 4 o'clock, slings the brass out 15ft away.
Today, I dialed my reticle into POI at a rough 100yds, and proceeded to engage steel from 400yds to 800yds with at least a 90% hit rate, as I was figuring out the trajectory difference between this 5.56 GRSC reticle and the actual Grendel ballistics in that scope.
Here's a picture of Buffalo Canyon from a previous DM Course. If you look at the top of the buttes on the left, then come down to the base of the cliff, that's where the 800yd steel is.

Out to 500yds, everything with the 5.56 M4 62gr reticle was dead-on center-punching the steel like it was easy. For 800yds, I used 700 plus one dot below the 700yd line for repeated hits on the steel buffalo.
Recoil is noticeably more than a 16" or 18" lightweight Grendel, but it's a much smaller gun with a stiff recoil Maxim Defense spring that is very positive in returning the BCG into battery, love it.
No steel was safe within my view, and it only goes up to 4x.
Using 2 different Elander mags, a 17rd and 24rd, it felt like everything was tip-top and absolutely no hiccups.
I'm interested to see how this sucker is going to do with 107gr SMK and 130gr RDF, as well as 95gr Controlled Chaos.
