It was worse than I thought...
On the last post I accused the shooter of not cleaning his Defender in six months of use. That prompted a note from him; "Hey, I cleaned that thing in October and I have video to prove it."
Ok, it was four months. But that's even more impressive. You can see from this video and the pictures below just how fouled a suppressor can get in a very short time.
He uses the suppressor on his 7.5" AR for SWAT and also on his .224 for feral hog eradication and loves it on both.
