Does a silencer QD hider affect accuracy?

[texasgrunt]

I am building a "long range" grendel (22" LW match varmint barrel) and just as I was about to call in the barrel order ran across several posts about running a can and how nice it is to not have to use hearing protection. I absolutely do not want to negatively affect the trajectory of the bullet. With that in mind, would it be a mistake to switch from a regular recessed target crown to an ACC or similar QD flash hider (order the barrel threaded)?

Thanks for helping the FNG out.

No opinions on this? Really? Or is it just too stoopid of a question?

Not a "stoopid" question at all. Some may call BS but a couple of my rifles actually shot better suppressed and they already were damn fine shooters. One is a TRG 22 using a thread on AAC Cyclone. The other an AR10 with a Noveske 1x10 barrel same suppressor. Only problem is I can't tell you why. My other suppressed with quick disconnect's shoot no better and no worse but must always be indexed to repeat same POA/POI.

Any opinions on the AAC Brakeout? How would it look on the end of a .920 dia barrel (not that looks are all that important)? How difficult would it be to mount and get radially aligned properly?

Suppressors will definitely tighten groups when properly attached. Single point attachments are the best way for the accuracy conscious shooter, though a F/A properly mounted will not hurt accuracy by any means either.

It all depends on the barrel, particularly length and thickness. For example with FNAR which has a thinner profile barrel the AAC 762SD changed my POI 6" low at a 100 yards. With my GAP 308 that has a Bartlein barrel that measures almost 1.0" at the muzzle the Cyclone suppressor put bullets in the same hole at 200 yards as it did without the suppressor.

My only opinion on the "Breakout" or any AAC for that matter is make damn you purchase from a dealer that has PHYSICALLY in stock. It took me twice as long to get the product despite multiple promises than it took form 4 to clear and that was 4+ months.

what set-up from acc did you get? was it one of their QD models and if so, how difficult was it to get the hider/brake properly aligned? thanks for the heads-up

I run a AAC M4/2000 on an M4 and a Remington 700 223 with the Blackout™ 18T Flash Hider. As stated above if the Blackout is put on correctly it should cause a predictable POI shift between on and off. That being said, I have more movement from the suppressor heating up the barrel than shifting from the QD. When I shoot my Remington 700 that barrel gets really hot after 10 rounds and the groups will open up. And, that is why I am changing barrels to a Bartlein 1:8 to see if that helps some. The barrel on the rifle was a normal Varmint Remington barrel and that barrel would get really heat up in a string of firing with the suppressor on.

I have 6 aac suppressors. Some are thread on and some are quick detach.

The accuracy of the guns with the suppressors is at least as good if not better with the can. I would highly recommend having a suppressor if you can swing it.

You can still have a target crown and put on a QD mount. the 13 degree target crown is the sharp edge where the barrel meets the lands and groves. The threaded portion is obviously on the outside of the barrel not affecting your crown...

The only QD AAC I have is an M4/2000 and do not use the 'brake' adapter based on the fact that in MY rifles @ least the 'flash hider' adapter's proved to be more repeatable with less POA/POI change but neither hard to properly align. It was of a lot harder to obtain adapters from AAC 2+ month wait in my case for either adapter.

I run 18T AAC brake mounts on my 243ai, 6.5x47, 220 swift & will run one on my Creedmore when done. Accuracy does not change with the brake. It will shift the POI since you're hanging additional weight off the end of the barrel but there will be no disruptance to cause accuracy issues. All my rifles have predictable & repeatable impact changes when the can is on.

The AAC brakes are VERY EFFECTIVE in reducing recoil. I feel the recoil pulse is much easier to shoot through when using the brake and no can. The can seems to lengthen the pulse and "push" me off target a little more.

Re: Does a silencer QD hider affect accuracy?

Thanks for all the help. I ordered the brakeout today and will report when I have it all complete. The supressor will be awhile, but since I was having the barrel custom built I figured now is the time to get it threaded. Mike at AAC was very helpful as was Sheri at Noveske.

Re: Does a silencer QD hider affect accuracy?

The can on my AR drops the POI straight down..accuracy is slightly improved, but the weight lowers the POI. Fortunately, it is really consistent, so I just drop to the correct hash mark in the ACOG and it works great.

So the inward cone on the crown not flushing up flat with the back side of the inside of the brake will not be an issue? This will create a cavity (cross section triangle shape)where the brake meets the crown. I know I'm using some "technical" terms, so forgive the clarity with which I am expressing myself...

This is the situation on a couple of my rifles with no negative affects.

After a few thousand rounds there will be some carbon build up, but again no negative effects so far.

Thanks for the info. LW already has my cash and my barrel order and I didn't think about the possibility until examining the brake that came in yesterday. Kinda hard to put steel back after cutting it off (on a barrel anyway).

I experienced the same thing when I installed a Fisher suppressor on the DC Vortex already on my M14s.
