| I recently bought a SKS "Paratrooper" (LOL) to leave out at my camp. While test firing and doing a basic zero at 25 meters, the gun shot 5-6 " below the X-ring. Sight settings were: rear at 100, front at factory (mid- point) setting. I continued to bring up my group to the X-ring, and ended up with the front sight +1/2 turn above lowest setting, and rear sight at 350 meters. Ammo used was Yugo M67, which shot out of my friends standard length bbl SKS right on target, and his sights are very close to factory setting. I'm thinking that because the "Paratrooper" was never a real military design, that the shorter sight radius may be the problem, since the front sights on both rifles are the same. The groups are tight, but I would really like to have the rear sight correspond to the correct range elevation. Anybody have any experience with this before, or any theories? |
| Your theory sounds reasonable, that the parts being designed for a 20" bbl don't work so well with a 16" (or whatever is is). However, at a shorter radius the same up/down movement of that front sight should make more of an impact on elevation than it would at a longer radius. If you have your front post bottomed out and still have to elevate the rear blade to get on target you do have problems. Does it look like your front post is original? With it bottomed out where is it sitting relative to the sight hood? Just wondering if you shorten it a bit or if it's already in the bottom third of the hood. |

Either move out to 110 yards or in to 25 yards. 50 yards is iffy for getting proper sight in. Set the rear leaf sights to either Battle position for 25 yards, or "1" for 110 yards (100M). Order or purchase a front sight adjustment tool. Brownells, Tapco, CTD and Midway all carry this. It'll run about $10.00. Move the front sight the opposite way you want the impact point to go. To lower the point of impact, you need to raise the front sight. To raise the point of impact, you need to lower the front sight. |

Thanks for the input, gentlemen. I just wanted to expound on what i did so far: I had an old AK-47 sight tool left over in my stuff, I used that , works the same (looks like the same tool?). The top of the front sight is in the lower third of the front sight ring, and the sight is original (as far as I can tell). From my old AK days, I remember that if I sighted in at 25 meters, the line of sight crossed very close to 25 meters to hit center at 100, with the maximum ordinate of .554 inches occurring at 61 meters. I did have the rear sight at 1, or 100 m. I believe the battle sight setting allows a point blank (minute of badguy) hit from 25 to 300 meters. Again, current setting for the rear sight is 350m, front sight is exactly the same dimensions that are on a standard SKS. If I cant get the rear sight set for the proper range, I'll just get a Williams rear sight, and that will for sure correct the problem. I liked the Williams I had on my AK. I'm just really curious as to why the sights are so whacked out. I remember reading years ago that the early Paratrooper models had problems, and I'm wondering if the sights were the problem. I got this SKS used (but in very good condition), no telling how old it is. Anyways, thats where I'm at on this issue, thanks again for the input. |
