Rustpot*** Update with velocity data. A review: SIG MCX Virtus and 300 BLK magazines.
What does a decent chronograph run? I need to get one for reloading anyway. I just picked up a 16" Q Honey Badger 300 barrel that I'll have built into a rifle by spring to compare with my 8.3" BA Hanson pistol.

Two of the better ones on the market are Labradar at $560 and Magnetospeed V3 at $380. There are recent discussions of both models in both the rifle section and the reloading section of this site.

sigfreundUntil recently (still?) there were several advertisements for the Labradar at $500.

BiggyThe main thing that I did not care for about my 9 inch MCX 300 Blackout Virtus pistol when I had it, was it's weight,it was much heavier than the 9 inch AR Blackout build that I have now.

sigfreundThe SIG MCX is no lightweight, and seems heavier (to me) because of its small size. With the SB brace, Aimpoint CompM5 sight, and plastic Magpul sights, mine weighs 7.3 pounds.
My primary serious purposes Colt LE6920 that is similarly equipped for the purpose (except plastic handguard) weighs only 1.1 pounds more.
Without trying to weigh the individual components, I suspect that much of the added weight of the MCX is due to its piston operating system and larger upper receiver to house it. The sturdy aluminum handguard and SB brace are no featherweights, either.
If I must hike across the Gobi and with any possibility of the need to shoot something, though, I’ll take the Colt and suffer with the extra weight.

BiggyAccording to the factory specs from both the manufacturers websites. The 9 inch MCX Virtus 300 blackout pistol weights 7lbs. A *16* inch barreled Colt model 6920 weights 6.95 lbs, with a 7 inch longer barrel.
