I am seriously shopping for a suppressor thanks to some great suggestions from CJS, off-line. I actually found a guy about a mile away that has 30+ experience in this accessory.
He spent 3+ hours today screwing 'cans' on my AR15 and firing them along with a few of his 7.62 rifles. I now know less now then when I started this trek.
I applaud this guys efforts BUT my head is spinning.
Once I was totally confused and ready to leave , he pulled out of his safe some nice selective fire rifles that I would NEVER be able to afford. Anyway, it was an education.
Thinking 5.56, I tried some suppressors that were long and some that were short. I tried some that weighed 10-ish oz. while others were in the 22-ish oz. zone. I tried some that were designed for hunting (10-12 rounds every 10 minutes or so) and some for auto-fire.
I was shown and fired some with nasty blow/gas-back while other had minimal to none. I heard some that sounded loud with low a decibel rating's while others had higher decibel rating but sounded quieter.
None of these required the use of electronic muffs as all of them were quite enough not to turn on the muffs. With that all written, the Silencerco was the loudest to my ear/rifle yet it had a very good decibel rating - Go figure,
One suppressor we screwed on the Rem. 700 and you could hear the firing pin hit the cartridge but then the round coming out of the barrel was of course faster than sound so you heard a CRACK!
OMG, my head is spinning! So much to pick from. The great thing was that with a few exceptions, e.g, like titanium, they were all less than a $1K.
CJS suggested I look at a DeathAir or a NG2. Well the Deathair is the teats and this guy just got set up with NG2 so he didn't have a demo to try; However, the overall selection is mindbogglingly.
Then there is how you attach the 'can' to your barrel which is a totally different animal.
Anyway, he was surprised at how well my Colt 6920 LEO handled all of the cans we screwed on her. Overall, probably put 30 rounds through her and the bolt was as clean as when I started out the day. He was shocked as "old gas" driven AR's I guess have a reputation for getting dirty fast with a can.
Anyhow, I will share with the group, my journey acquiring my first suppressor.
On another note: IF your state allows them, please think about acquiring one. Nothing better than shooting without muffs on.
