How concerned should I be about the durability of a suppressor made of all 316 stainless steel. I was told that they function fine so long as I shoot responsibly. That's kinf of vague.

Suppressor will be used on 16" barreled AR type rifle with switch for running suppressed.

Should I be looking at a suppressor made of titanium and inconel due to their higher heat tolerance?

Also does alot or some of the heat from the suppressor transfer to the rifle barrel?

I've shot a couple of rifles with suppressors recently and even the bolt action remington 700 got pretty hot pretty quick.

What kind of switch is that? Never heard of a AR type rifle with a suppressor switch. But I would like to learn, any pictures?
Thanks: Phil

It's a Larue obr 556. Here is quote from Larue's ad.

"All gas blocks will feature our unique Port Selector Technology (PST), a two-point adjustable gas selector that allows optimum function between suppressed, and unsuppressed operation at the flip of a switch."
 
Re: Suppressor and heat build up

all suppressors turn noise into heat,some do it better than others, shop around for what works best for you.

switches and adjustable gas blocks all end up doing the same thing, restrict the gas.

Nice.

I shot a friends 16" barreled AR15 today with an Innovative Arms Grunt suppressor that is made of 316 stainless steel. A few observations and temperature reading on barrel and suppressor.

The suppressor was plenty quite for me, I did still wear ear protection. Noise is of course quite subjective.

The spent brass was very dirty. That is probably standard but I did not think about it.

When shooting from bench with plenty of time between shots the suppressor temp was in the 200 degree to maybe 250 degrees. The barrel did not get that hot in comparison to the suppressor even at point of attachment.

When we fire about 15 rounds one every 1 or 2 seconds the suppressor temp went to the 450 degree range. Barrel temp was maybe 150 degrees.

The suppressor was always hotest in the center area of the suppressor.

The rifle stayed on target way better than my 16" barreled rifle.

All temps are averages based on what I recall and they were taken with my infrared temp gauge. I think the ambient temp was about 70 degrees.
 
Re: Suppressor and heat build up

That was the first thing I noticed when I started shooting suppressors - they get really hot. If you shoot a lot the barrel gets hotter and it will start to change POI. I had a Remington 700 - 223 that I was shooting an AAC M4/2000 with. After about 5 rounds the barrel would get extremely hot and if I continued shooting the groups started to get larger.
