The problem isnt timing, it is the length and diameter of the spare barrel sitcking out in front of the threads.

The FSB of the Bulgarian and Russian rifles are a bit different on the muzzle device timing. The retainer pin location are different. A 24mm muzzle device would work fine on both, like the manticore night brake. However, putting a Russian krink booster on a Bulgarian muzzle will off set the device.

Would cutting a new notch in the booster solve this?

I debated about this topic as well, because I'm awaiting the arrival of my tax stamp so that I can SBR my SLR-107CR. I spent a lot of time talking with a guy who has already SBR'ed his, and he has a Russian cone style brake on his. He swears that it has caused him no issues whatsoever, and that it goes on just fine. So... That's what I have purchased for mine. I am hoping that it will work okay without any problems. Worst case scenario, I will buy something else. For now though... I'm confident that what I have bought will work.

There was an old thread in which TX-Zen, Nictra, and others have discussed the indexing issue. If I remember the conclusion of that discussion correctly, Russian AK-104/105 boosters work fine on the Bulgarian SLR-106CR/107CR FSB. It is not perfect positioning, but works nevertheless. Maybe TX-Zen and Nictra can chime in. ETA: Here's the link to that old thread. |

They will work either way but the cut outs on the tip of the cone won't be at 3 and 9 o'clock if you cross the manufacture.
So it's really only a cosmetic/correctness thing. |

takes 5 secondrs to cut a new notch for the offset plunger. Not a big deal.
The Bulgarian flash hider has a wider flute at the 6 o'clock position. One could argue that having it rotated 15 degrees to index off the CR plunger is an improvement - like the slant brake it counteracts the right hand rotation of the bolt. |
