Certainly!
The rifle was built specifically to what I thought would suit me the best for 3-gun. The qualities I sought were light weight to swing around faster, but I also wanted an 18" barrel so I could squeeze a rifle length gas system on it. Of course on top of all that I wanted minimal sight picture disturbance when firing for fast follow ups. The lighter the rifle gets the harder this gets as you have less mass working in your favor.
I got the rifle light by using the 2a armament balios lite milled receiver set which is very light weight. Even the picatinny rail is milled out on top, the brass deflector is minimized, there is no forward assist...it is light. On top of that I used a handful of titanium parts like the pistol grip screw, takedown pins, safety etc. The handguard and stock aren't the lightest units in the world but on the lighter side, the stock is the luth ar mba-3 with the adjustable bits removed as I didn't utilize them. The handguard is a carbon fiber 15" long octagonal handguard. 15" was important to me because I have long lankey arms and I put my support hand all the way out there to drive the gun. I got octagonal so there is a flat on the underside to rest it more securely on barricades and things like that. I also shaved weight by paying a few bucks more for a fluted barrel which is a White Oak 18" SPR fluted, although now they have even better options.
I kept sight picture disturbance down with a big JP 3 port muzzle brake, combined with less reciprocating mass and consequently, less gas in the system. Working from front to back the gas is turned down with a SLR titanium adjustable gas block. The BCG is a stainless LMOS one from JP, and the buffer is also the JP LMOS rifle length buffer in a rifle length tube (rifle length wins in the performance department hands down). That's all in front of a Woff -10% recoil spring which allows the gas to run even more turned down. Less mass and less spring needed to move around means less gas = less energy = less sight picture disturbance.
The dot is a Vortex Spitfire AR which is the prism style red dot. I enjoyed shooting matches with it because I feel it has several advantages over traditional dots. The larger circles around the dot are measured in MOA (22 and 45moa respectively I think, but i forget) and you can use them to gauge hold over, because in 3-gun you aren't turning dials and practically speaking you need to hold over everything. Holding over a target at long range with a red dot gets weird if you have only the dot, as the target is swimming around under your dot in empty glassy space and it gets weird.
The rifle weighs about 6.5 pounds with an empty magazine and the optic on top of it.
I hope this was helpful, it turned out longer than I anticipated LOL.
