I really like their charging handle. But I didn’t want a left side charging handle.
Started with a BCA upper with right side charging.
Chopped the carrier in half-ish.
You can see the solo300 handle on it.
Found a 16” barrel in the parts bin. Mounted a chopped gas block backwards so the gas isn’t going anywhere.
Added a lightweight barrel nut and found some eBay carbon fiber tubing to make a handguard, similar to what you can get for a PCC. Almost done other than adding a few holes to attach the handguard to the barrel nut.
If I really like this, I may plug the gas port in the barrel with a tapped 6x40 screw and turn the barrel diameter down a bit to delete the backwards gas block.
Borrowed the side folding stock (Sig hinge/farrowtech carbon fiber stock) off my Charger SBR to put on this spare lower. Lightweight ATI stripped lower assembled as a pistol with the KNS pic rail rear.
