If the front sight post in my new slr-107 if off slightly to the right within the front sight base does this mean that something is canted?
The barrel and front sight base look straight but like I said the post is a little to the right. I can take pics after work if that helps. |

My O PAP's front sight base wasn't canted, but the front sight post was to the left a little when I zeroed it. Found out that one of the holes on the rear sight base was oversized allowing the rear sight blade to cant to the right a little bit.
It'll be fine, though. |

Not an slr-107 expert by any means, but if your front sight is bent, you'll have a heck of a time adjusting the elevation when you sight it in. The sight post will "flop" to the other side when you give it a half-turn. That will change your point of impact either left or right. If you give it a quarter turn, it will effectively reduce of increase your elevation change since it will effectively be "shorter" to your perspective from the rear sight.
I've heard you can rebend them. You can do that on AR style posts too, but it's almost always better, or certainly easier, to just buy a new one. To see if the post is bent, just try turning the sight post. If it's bent, you'll see that it bends the opposite direction after you've turned it 180 degrees. Although t's unlikely, it is possible that the hole that it's screwed in to was drilled at an angle. If that's the case, the sight post should remain canted in the same direction as you turn it. If that's the case, you would need to return it for repair. |

Just about every single AK rifle I own has the non centered FSP in FSB, including SGL, SLR, O-PAP, Polytech Spiker, Preban Yugo, Preban Hungarian. So yes, its completely normal for AK rifles to do this. Since the FSP is only slightly off, its a good thing. In my whole collection, my Preban Yugo, O-PAP, and SLR rifles has the least amount of right or left 'shifting' to the FSP in FSB. |

Look at the front of the sight base and see if the drum that holds the post has an index mark that aligns with another one in the sight base, or maybe is slightly 'off'. I apologize that I don't know crap about the Arsenal guns, but if it is a 'kit' gun assembled in the US, it may have a minor rotation of the sight base. If it's a factory gun that was assembled in an AK factory overseas, maybe with a mag well modification here, it should be 'straight'. But as already said, even older 100% factory-made AKs will usually have the sight post a little off as the result of sighting at the factory, so as long as it shoots where it's pointed, there's nothing 'wrong'. If, however, the post has to pushed very close to the sight ear, there is something amiss, either with the 'cant' of the sight block, the rear sight or the barrel.
ETA: Many have also noticed the 'muzzle brake effect' when sighting in after changing the muzzle attachment, where the new device changes the point of impact, even with no bullet contact on it. I'd say if your rifle sights in with the post just a little off the center with the muzzle attachment you now have, it's probably best not to mess with anything. |
| Arsenals come canted from time to time like all AK's. The front sight block is off but they move the sight post within it so its on target at the factory. My SLR 95 FSB was to the right .25".....gun shot fine but it bothered me so I had a gunsmith un-pin the FSBt, center it and re-pin in place for $35 |

OP, You can use the 'table test' to see if rear sight leaf is perfectly aligned with the front sight base. It is probably the easiest way to test. -find flat surface -turn your rifle upside down -place your rifle down so it stands on rear sight leaf and front sight base -if theres any cant on the components, you will see a little gap/space between flat surface and FSB. This test is dependent on whether the FSB and rear sight leaf are perfectly machined/cast. You might have a perfectly straight rifle, but if the RSL or FSB is a little short on one side due to minor imperfection of machining, it will show up as 'canted' using table test. The harder way is to use a straight edge, but will be more precise to find out if theres any cant on your rifle. |

Forgive me if I'm mistaking the question, but the FSP is supposed to "drift" left/right to adjust for windage. Drift right to make you're POA land to the left and visa versa... Is that what you're talking about? Yep. This is what I am talking about. Arsenals supposedly come zeroed from the factory so if the FSP was a little off it would lead me to believe that something is canted. |

Totally normal. If it shoots to point of aim, leave it, nudge it a bit if it doesn't. But trust me, totally normal for an AK front post to be a hair off center, most i've had were off a tad, I think they either test fire and adjust or bore-sight them from the factory, because most AK's i've ever had were dead-on right out of the box. In general, if you are a perfectionist type of person, and the little things bug you a lot, probably best not to mess with AK's as there will be even more imperfections the closer you examine everything. Unless of course you buy a Vepr in which case you can expect perfection.

Arsenals supposedly come zeroed from the factory so if the FSP was a little off it would lead me to believe that something is canted. Your rifle is fine. Pretty much every firearm needs some wind age adjustment to zero. It's noticeable for AKs because the adjustment is done at the front sight. It's only something to be concerned with if the front post had to be moved waaaay off to the side. Being a little to the side is normal. |
| Mine is the same way. According to the manual, the rifle was sighted at the factory, and the front post may not be perfectly centered. This is common. I have not had a chance to shoot mine yet, but I did visit a gun shop and checked out a few other Arsenals. The majority were off center. |
|
Oh noes! Not an allmighty Arsenal with a canted sight!!! How could such a thing happen?
Oh, right, it's an AK. You, and your rifle will be fine OP. This is why the sights have windage adjustment, so that the post can be moved from the center to point of impact. |
| The rifle is perfect. Note the index marks on the drum and base. The rifle was sighted and marked. I like to keep my sight post turned so I see it the thin way. It simply opens up the field of view - not really important, and the 1/4 turn you make to do that doesn't make much difference. |

Same on my WASR - canted rear sight leaf due to one holes for the leaf tabs (ears, whatever they are called) is bigger. Front sight base is straight, but post is moved over a good bit to the right. |

Arsenals supposedly come zeroed from the factory so if the FSP was a little off it would lead me to believe that something is canted. Everyone missed this. His sights aren't canted. He just assumed this, because it was shooting to the right and being "zeroed" from the factory he though it wouldn't do this. With that said, just because it's "zeroed" from the factory doesn't mean it will be zeroed at all and every range you're shooting at. YOU actually need to zero your rifle with whatever ammo YOU choose to shoot. Also lots of ammo will vary in POI from your last zero; however once you learn the hold-over and ballistics of your rifle, YOU should be able to get on paper. I repeat, just because it's "zeroed" at the factory doesn't mean it's going to print dead center for you. Also, if you didn't receive a target group from the factory, I doubt it was actually sighted in. At most, boresighted.  '
Also, remember an AK is not a tack-driver rifle. 2-3 MOA rifle at best, being closer to 3. Yes, it can be smaller, but let's keep it realistic towards to average and not the outlier. P.S., make sure to get an AK sight tool so you can actually zero your new rifle. Quoted:

This is correct. |

The front sight block on my Romanian AKM was "canted" to the left but hit to point of aim.It bugged me the block wasn't dead level so I "corrected" it and ended up having to move the front post all the way to the left as far as it would go to zero it!.
Needless to say I knocked the pins back out and lumped the block back to the left, rezeroed it (post ended up more or less central between the ears) and learnt to live with it |

If it was in the UK, what mod do they do to make it UK compatible? |

perfectly normal thats simply where it ended up when zeroed,my new SLR107 is slightly towards the left of center.if it were farther off I would correct it but for the tiny amount its off i will leave it alone. |
