supressors

Hello friends, a week ago or so we had a thread going about flash hiders that lead to a questions on supressors. I needed to get back to the question about changing the POI with the addition of the can. I spoke to my POCs with the G2 and he says that while, yes adding anything to the barrle changes the hamonics of it, some can makers are claiming they affect the POI shift less. My partner who owns many of them says some keep a close POI but it is mainly due to the type of mount and can design. But what changes the POI most is that in order to have an effect supressor (quite) you need to drop the velocity in the tube- hence changing the POI. You don't want a slim fast load in a suopped up hyper vecilty round, and if so you still get noise with a can. My brother how shoots a 22 cal can also shoots sub rounds to acheive the silent kills. Hope all this makes sense.

Last a reader/writer mentioned the US Army competing with them? I never heard of it- so inquired and the report from teams (MC and Army) no one competes with a can that they know of. I was at SA TX a few months ago when the NATO SPEC FORCES competed- no one used cans. And I spent the past 27 years training spec teams and competing- no one used cans. BUT No telling what secrete squial stuff they have going on that old "has beens" don't know about. By any means cans are fun. Keep Center. JHG
 
Thanks Jack, yes sir I did misunderstand that one. I was most curious if some of our forces played a spook game that I was unaware of.

Yes you are correct- most all the mil spec team rifles are using flash hiders. But about 8 years ago the DCM, now called CMP changed the exterior appearence rule allowing service competition rifles to be use without a flash hider.

So about 50% civilians don't have them, and 95%+ mil use them. Keep center, JHG
 
who cares if it changes the POI once you dial it in your done. And if for some reason you want to shoot with it on or off just memorize how many clicks from zero it is or make a cheat sheet.
 
agreed, not sure why the question was asked- I just needed to confirm. In my opinion I rather have 4k FPS whacken a yote at 400 yards than a sub sonic round anyway. And when I am worried about noise I grab the hornet and leave the blasters at home. I have shot great 200+ yards groups with cans. Maybe if I owned one I would think differently. thx jhg
 
The KA supressor I used for a while was the best(on an M4). Between the can off and on- the POI shift was so small as to not be a factor(this was combat- not paper punching though). Yes it did seem to slow the round down so it dropped a tad more at range- but the difference between can off and on was within the threshold of my range estimation misjudgement so again- didnt realy matter (unless you are at a range with fixed distance targets).
 
Usually, Suppressors give a "free bore" boost in velocity, as the gasses propelling the bullet continue to push the bullet through the "can".

The suppressor has nothing in it to slow the bullet.

correct, the can has no effect on the velocity, the velocity has effect on how well the can works. So if your rifle is sighted in at 200 yards with 2700-4000 FPS it will not make a real big difference in the BANG. To get a quite bang from a weapon you need to use s slower (sub sonic) round, therefore the two rounds are not the same and the POI will be different. Extremely different, meaning no Minute of Coyote POI. Maybe this makes better sense. But if you have the right scope and keep good notes- this will not be a challenge becasue you can get zeros for both rounds.

Some where out there is data identiying what velocities work best with different calibers. JHG
 
My suppressor is a Gemtech. When mounted on a 223 and 221 fireball the gun shoots 6 inch lower with the suppressor on. I must sight gun in with suppressor on. I love the thing. Keeps noise down big time so i don't disturbe the farmers at night. I THINK THEY SHOULD BE LEGAL ACROSS THE BOARD JUST LIKE EUROPE. Gun sounds like a 22 long rifle when shot.

I have two suppressors at the current time. Both are AAC one for my .223's and another for 22 rimfire. For the 223 can I have quick attach mounts for the rifles I want it on. I have noticed minimal POI shift but not much.

Prior to purchasing my cans I spent a great deal of time on www.silencertalk.com. Got alot of good information and have been very happy with my purchases.

Only downside is that in WY I can only punch paper with them.
 
Even when punching paper, an advantage of the "can" is that there is no "Bang!" at the muzzle, just down range(supersonic report).

The other adventage is for the "Patrol Carbine", you will not receive hearing loss if you have to deploy the carbine. It is very nice to have no loud blast that the 16 inch .223 will provide, instead the noise of the super sonic report is downrange.

Even with standard (non-subsonic) ammo, the suppressors work great for making the muzzle report quieter.

Good shooting,

yea you have to subsonic on any type of can to get the quiet out of it ,, or you will still get the crack.... the suppressor works by haveing well manly all they are is washer with a deppress in the middle with a hole throught it ,, is all it is
 
Karl, you shoot at Ben Avery range? Awesome place. Some of my old team mates still run the ranges, mainly 1000 yard stuff. And shoot and compete with cans in combat type matches. that is a great, but hot, place to shoot and hunt yotes. Lots of fond memories there. JHG
