Just got back from the range with some chrono data unsuppressed and suppressed.

Unsuppressed with the Bootleg gas system fully open, it wouldn't fully cycle 90gr TNT Federal American Eagle factory load, which is good to know.
Suppressed, it has plenty of gas for the 90gr TNT, enough so that I turned the gas down 3 positions. Ejection was at 4 o'clock unsuppressed and suppressed with the final gas setting, very well-behaved, a joy to shoot. I didn't notice any difference practically between shooting this suppressed and longer-barreled rifles that I've shot suppressed, as shooter's ear suppressed was very pleasant. I don't ever want to shoot it without the can, not that it was crazy unsuppressed. It's not bad at all unsuppressed, don't notice the difference between it and 16".
My younger kids' first shots from center-fire will be suppressed.
