K31 muzzle brake close to $100, any cheaper ones?

Re: "The K31 is a straight pull bolt action with a moderate recoiling cartridge. A muzzle brake is of no use to you here (aside from a weird ascetic in my opinion), muzzle brakes are designed to reduce muzzle flip on semi/full auto rifles to aid in keeping near target in FA , or on target in semi. "

Someone must have forgot to tell the Swiss this ! I have three K31s, and they all have Swiss Arms brakes on them. The "before and after" effect is substantial. I didn't enjoy shooting this gun until I put brakes on it. Originally would recoil as hard as the M38s I used to have. Can't say I enjoyed the recoil at all. Recoil is now about the same as my .243. It's less than the recoil of my Swede mausers in 6.5. Recoil aside, the effect on accuracy is reason enough to do the install. All three of my guns had their hundred yard groups almost halved when the brake was added. It definately increases the blast noise, but it means nothing to me, as I always have muffs on anyway.

As Tac stated, I'm fairly certain the Swiss are well aware foreigners put breaks on their rifles...that's why they've disallowed them in competition!? Further, I would suggest that the only thing the break has done to improve your accuracy is remove your flinch. The break isn't rifled, so you haven't added any length from chamber throat to muzzle. Cycling the bolt for the next round will take you farther off target than the break could ever compensate for, and in comparison to the British .303 or Russian 7.62x54 (particularly in the carbine offerings) the K31 is a pussycat, so yea, double up on the "light days" under your bra strap and nut up! :p

BahahahahahaLaugh2...The best! The very best!
 
Great for getting the rest of the family to enjoy shooting the K31.
Seen kids, both boys and girls as young as 8yrs old firing Gp11 and really enjoying it.
Then there's the petite 45kgs ladies, and finally the 90+ yr old grandpaws(Opa's) who don't have to worry about brusing.

Can someone please explain why my three K31's have much greater accuracy with the brake installed. The flinch factor has nothing to do with it in my case, as the guns were fired from a Caldwelll lead Sled, anchored with 45lb of lead scuba weights. Butt of gun is in the sled, so I'm not seeing how there's any human factor involved. With GP11 ammo, my braked groups are half the size of those that I shoot if I remove the brake. Exact same batch of ammo, no human factor that I'm aware of ?
re: K31 is a pussycat compared to Rusky carbines and 303. Not sure what guns you're shooting, but I found the complete opposite. All the guns I've owned had just the original military butt plate on them. I have 4 Enfields (no jungle carbines though)that I'd rank well below the K31 for recoil. I'd put my 9130 Mosin next (shooting Privi FMJ) with a slightly harder recoil, but still less than the K31s. I'd put the K31 on par with both the 44 and 38 Mosin carbines that I used to own.
 
Not always the case. There have been a few cases where accuarcy was initially worse with the clamp-on brake than without it.
Most recent case is working on tuning his rifle so it shoot as well with or without the brake.
Each rifle is a case onto itself.
 
I have 3 K31's, and all three guns have improved accuracy with the brake added. Same results whether it's me, or my wife shooting them. An added bonus that I've found with the brake is that you can see your target impact/point of impact through the scope, due to the reduced recoil.
 
I'm definitely getting a brake now thanks for the input. Now my wife will shoot too. And it will look awesome and hopefully louder.

Really confused!? The K31 that I shot had half the perceived recoil of the other calibers I mentioned. I was shooting factory loads in the K31. Can anyone put the ballistics up inclusive of ft lbs of recoil?

I've also shot both the Enfield {jungle} carbine and an M44...these are not fun after 20 rounds, and there is no comparison to the K31 at all. (I also own and often shoot a No1MkIII and a No4Mk2 both in full military furniture, which are still fun way past 40 rounds {factory loads})

Not fun after 20 rounds! That will keep ammo costs down.
 
I have fired my K31 from the prone position several times, and the recoil is negligible. The thumping I get from my 8 mm VZ24/47, now that's a different story.....

A good muzzle brake can improve accuracy because it strips gas away from the base of the bullet as it leaves the muzzle, reducing the chances of the bullet being deflected by the emerging gases. Suppressors do the same thing.

I suspect a lot of it is poor stock fit. None of the cartridges mentioned have particularly nasty recoil in the overall scheme of things. I have an inherited sportered Enfield with a short buttstock that fits me very poorly. It is perhaps the nastiest rifle I have ever shot off of a rest because of the poor fit. My tang safety Ruger 77 in .338 Win Mag is much more comfortable for me to shoot than that Enfield, despite having twice the recoil.

I have some Portuguese surplus 8x57 that is loaded HOT. It makes any Mauser into a nasty thumper...
