Silencers/Suppressors: Questions for Gun Geeks
« on: February 17, 2015, 09:01:24 AM »
Do they change the accuracy of a rifle?  If so, is it because it changes the harmonics?  If so, are there adjustments you can make to your load, or anything you can do to regain the accuracy that you had before the barrel was threaded and silencer added?

I'm curious what the experts opinions are on silencers.   Are you guys seeing them at the ranges?

Don't have one myself, yet, but they really are most effective with subsonic loads which will definitely require a adjustment of sights as the reduced velocity will most likely have some affect on point if impact esp over longer distances.    How much will depend on what you are starting with.

I really can't say if it affects harmonics, etc.


I will say that even with the best load they never seem to be as quiet as Hollywood would lead us to believe.    LOL


That's pretty much all I can offer, I'm sure there some here with much more knowledge than I on the subject.

I understand it could change the point of impact.  But does it effect the consistency of the point of impact?

I have one on my patrol rifle, AR-15, and two more of our guys do also. I know they did change the point of impact from just screwing the suppressor on.

From what I understand, suppressors work better when the round is subsonic.  Given that the bullet is travelling at a slower speed, your trajectory is definitely going to change.  I don't have any personal experience, but IMO, I would think that if your load is tailored correctly, taking in consideration your barrel twist, bullet type/weight, and speed, your accuracy shouldn't suffer, but your range would be shorter.  Also, perhaps just as important, practice, practice, practice.

Not that I am aware of.   I think once you make the initial adjustments you are good to go.  But I am commenting based on what I have heard, not what I have actually experience myself.

The harmonics will definitely change. Therefore POI will change too. There are different styles and types of suppressors and they will have different effects. I only have one and if is for Ol' Rem the 223. By today's standards it's a dinosaur 23" long 2.25" dia, weighs 6.75 pounds. I have a special barrel to use with it. I had to gather my dope when using it so the POI was exact. As I recall the rounds wound drop an additional 2" at 200 and spray left .75".

Check your states rules quite often you must register them and pay a special tax.

I have GemTek Suppressor mounted on a Rem 700 Varminteer in .308. I use this for deer reduction services so definitely want an accurate firearm. The Suppressor does a few things - not sure that changing POI is one of them, I do believe that it does increase my ability to be consistent whether using factory or sub-sonic ammo.
Adding the extra length of a suppressor does increase velocity if only 50 or so foot pounds. Additionally, the suppressor almost eliminates muzzle jump and certainly lessens recoil so that the 'flinch' reaction in anticipation is negligible. I can and have placed the firearm with bipod down and sand bag under the butt peeked through the scope and just touched the trigger and get constant groups of 3 shots that can be covered with a dime.
If using sub-sonic the groups get even tighter and I leave the range much better off for the wear.
