Best muzzle device for precision rifle?

I’m looking to get a Sig Cross 308 with 16” barrel.

I’m wondering what the best muzzle device is for precision target practise at the range? (Secondary use would be very occasional hunting).

Brake? Flash hider? Linear Comp?

Although expensive, I’m thinking a Surefire brake and a Warden Linear Comp that can be added/removed might be a good combo. The linear comp could be helpful if the range gets back to full capacity one day and/or shooting prone I suppose. I could also use the warden on my WK SBR which is a bit obnoxious.

Thoughts?
 
Griffin Armament 30SD Suppressor Mount Flash Comp, 7.62 5/8X24 TPI How about this? I saw it from another sig cross 6.5 cm owner’s post.
 
I had actually reached the point where I wasn't running muzzle devices anymore, figuring that on a bolt action rifle of modest caliber they mostly just look tacticool and annoy friends in adjacent lanes at the range. But during COVID doing the antisocial-distancing thing is popular so maybe keeping the next lanes clear is a good idea for now.

The one good reason for running a muzzle brake is on big/magnum calibers, where recoil can physically hurt you or even just give you a bad case of the flinches. And a compensator on a semi-auto so you maintain sight picture and can put in a quick second shot is good for that sort of competition. But recoil has been and gone faster than I can work a bolt, and I'm not running anything much bigger than a .308 so I think I'm good without.
 
I just spent the morning and early afternoon grouping my 6.5 CM @ 100m both with and without a Lantac Dragon Muzzle Brake specifically to determine if there was an effect on accuracy. On average, using 3 different commercial match loads the groups varied from just over 1" to as small as .5 MOA (depending on the load). Hornady 147 Gr ELD Match was the winner, delivering slightly tighter groups than the Federal 140 Gr Gold Medal Match. As to the question of compensator effect on accuracy, I found that my groups WITHOUT the compensator werre slightly better than with. By slightly I mean perhaps a .2 MOA difference (if that). The reduction in perceived recoil with the compensator is dramatic, however. The Lantac Dragon reduces the perceived recoil of 6.5 CM down to 5.56mm equivalent. Not that 6.5 CM is particularly punishing, but why absorb recoil that you don't have to? The compensator's minimally negative effect on accuracy is well worth the significant recoil reduction IMO. Your opinition may obviously vary, but I am going to run with a comp so long as it is not bothering anyone. I can always spin it off in a hurry if necessary, secure in the knowledge that my accuracy may slightly improve with no shift in Point of Impact.

My experience thus far is that (in my hands) the 6.5 CM SIG Cross is on average a .75 MOA performer at 100m. Not bad for a crossover precision/hunting rig.... Now to stretch its legs out to my club's 800m max range!
 
How about a tuner/compensator if it's a precision rifle? I haven't tried one yet, but would like to.
The Warden or similar is a nice way to get reduction of recoil, but then also use the shroud if you want less concussion and noise. I have to imagine it would mess with the harmonics though? I don't think it's light.

Otherwise any well made brake will work and it's pretty much user preference. The larger and more rearward the gills the greater the recoil reduction and concussion/ noise, vise versa.
I'd test or handload more accurate ammo with whatever muzzle device attached, again due to harmonics.

Precision Armament M-11 is an excellent recoil reducer
V7 titanium micro is small and lightweight
Check out the Witt Machine Sound Mitigation Equipment or the Jmac Customs X Series muzzle device and shroud
 
V6 Gamma w/ CAGE for mitigation.
(manuf by Aero Precision)

SureFire SOCOM w/ Warden or Surefire Fake Can.

Any Blast Deflector is going to increase felt recoil...even on a direct impingement platform.

The V6 Gamma is efficient,but my SureFire cans adapt well to the SOCOM brakes.
 
I think you need to figure out what you want from your muzzle device first before you choose what you'll buy. If it's precision shooting that you want to do then you should go with a brake since that will allow you to stay on target and spot your hits. If it's for hunting and general plinking then you might want something that will reduce the sound being projected rearward and prevent dust being kicked up.

As for tuners, I think it's unnecessary if you reload since you will find the load that matches your barrel harmonics. If you are shooting factory loads then yes the muzzle device vs not having it will slightly affect your accuracy. Testing the different ammo will let you figure that out.
 
Tuners would be for rimfire where you have to use factory ammo and need a tuner to fine-tune. With centrefire you adjust the reloading parameters to the firearm.

I like the M4-72, MDT Elite, little bastard, heathen and Nordarms Ti brakes, and those are across hunting and comp platforms. Would like to try one of the 419 brakes.

I hunt with ears. Your mileage may vary.

The M4-72 gets good reviews... how's the blow back? I'm putting this on a 16" barrel so I don't want to have to shoot with a blast shield on my face :D
 
Very little blow back, relatively cheap, and cuts the recoil better than most other brakes I've used. It is noisy, but on par with the others I listed and by no means as bad as some others I've tried. My one beef is that I really wish it self indexed. I'm hoping they bring out a gen 2 at some point.
 
I’ve ordered a DPMS Miculek brake for $69 to start with. It gets good reviews, is cheap and most importantly in stock. It’s so frustrating trying to find anything in stock right now. Anyway, thanks all. I may upgrade to some of these other suggestions down the road… so appreciate the advice.
 
I’m going to second the VG6 Gamma, I have them on all my now banned rifles and put one on my ultralight in 6.5 prc. I wasn’t sure how it would perform on a bolt but it shines. It virtually eliminated muzzle rise to the point I can keep my scope on target much like my heavier PRS rifle in 6creed. Surprisingly it added some velocity as recorded with a lab radar, but definitely changed the harmonics of the barrel and shifted the poi vertically around 1.5 moa but didn’t affect group size.
