I didn't shoot either of 'em. I was just making fun of the long haired hippie (John) who kept trying to get them to run.

Do not blame John's gremlins on 300blk He has gun cooties

Nice! Maybe if .300 BLK becomes more common.

Interesting that Haley was using a Spikes Compressor. It was one of the few 300 BLK ARs that operated without any malfunction firing suppressed, unsuppressed, supersonic, and subsonic in a review of 10 or so models I saw a few months ago.
