How much of a difference does the slant brake make compared to an AK without the brake?  I am new to AKs and just wondering if it is worth the extra money to get a slant brake.  Thanks for the info guys.

Its spelled BRAKE.  That said, theres no real effect that I've noticed in semi auto.  Its on there for full auto.  Really helps complete the look though.  

I've had the pleasure to fire a brake-less AK, a Slant, and a '74 style brake in the same day. It's my opinion that the Slant & '74 style brakes allow faster follow-up shots. The '74 style brake reduces general recoil considerably while also increasing the report. If you want to make your rifle look authentic and some reduction of muzzle rise, get a slant brake. If you want a great improvement on recoil & muzzle rise, get the '74 style brake. I would if I hadn't already bought a slant brake, and I wasn't going for the smallest legal rifle.

I had a nut on my romy and went to a slant brake while at the range one day and noticed a huge difference.  Never knew they did so much till I tested back to back.  If you are shooting from a rest or something then its no real difference, but standing up it allows for tons quicker follow-ups.  I could only imagine on full auto...  Dont see how it could be very practical without a brake.

I had a slant on my SAR-1 and it made a big difference when I was standing and shooting...

When I shoot my SAM7 Carbine I notice a big difference without the brake on. My Vector underfolder has a slant brake and seems a little more controllable with it.

You can always buy surplus slant brakes they aren't that much money.

Slant brake is $15 @ Brownells. US Manufactured.
