Does it make you feel good to refer to others (many likely otherwise like-minded) of being clueless, 'soft in the head', or idiotic? No response required, but you might consider being a little less harsh. Just saying.
Not directed at any specific person at all, but rather a story of my previous cluelessness. I remember how I felt after investing 1k and 18 months of time, when I ignorantly screwed on a high noise reduction/high back pressure can on an AR I had set up for pigs at the time. I knew it would make some difference in how quick the rifle got dirty, but I wasn't aware of or ready for exactly how bad it would be. I can assure you I was extremely disappointed and felt like a complete moron ( this is my foray into less-harsh land, look at me go..) And I had to talk to NUMEROUS people and scan NUMEROUS forums before I found someone that actually HAD the presence of mind, experience and higher expectations from their equipment, to find out what actually worked. So another 1.2k and another 14 months and I had a flow through can that performed on an AR like it should.
It was an expensive and time consuming lesson, I'm trying to pay it forward for those who were in the same position as myself. Think Gandhi, Mother Theresa etc...
Can technology is changing by the day, I'm not up to date on every single manufacturer, nor claiming to be, but my point is this. On an AR, if you DON'T run some sort of LBP or Flow-Through can, you WILL get your feelings hurt by how quickly it fouls and the subsequent needed cleanings. I sure did, it and was totally unnecessary provided I had the correct , objective information. ( Keep in mind this was several years ago, when flow-throughs just got on the scene.) How important that factor is to any specific individual, is up to the individual. A guy who is going to shoot 13 rds a year, probably doesn't care. A guy that has lots of pigs to shoot at night and may shoot 85 rds in 3 nights, will care quite a bit!
At the risk of being too adamant with my own experienced driven opinions, I will also say that I've gone to piston kits on all my AR's. Piston driven with LBP cans is the best option I have found to date. So that's what I recommend. YMMV
Bolt guns, not a factor, I go for most decibel suppression.
Thank your time. I celebrate diversity, and love all humanity.
