Based on this thread:
http://forum.saiga-1...showtopic=24126
and Oldandslow's post, I installed the BHO spring with the LONG leg toward the rear.

However, in this thread (and the associated video):
http://www.youtube.c...h?v=SHxMxKgM6qM
RJS34 mentions installing the BHO spring with SHORT leg toward the rear.

And the thing is, with the long leg toward the read, as I have it now, with the safety lever in the 'safe' position, the tab of the safety lever (the tab that blocks the trigger) also interferes with the leg of the BHO spring.

In other words, with the safety on, the BHO spring has no down-force on the BHO lever because the spring is catching on the safety tab.

It also seems the BHO spring needs a bend in it toward the inside of the receiver to make sure it stays on top of the small bent tab. Thought?

I can pretty much see the answer, but I wanted to get some advice from the experts first.


Thanks,
Fogaban

I originaly installed mine with long towards the rear, it was very week and caused issues with it not wanting to let go of the bolt. I re-installed it with the long leg forward towards the mag. I also made a small bend at the end of the short stub so it would rest on the BHO better. After I did this, she has been working great. Lots of tension and no mis-haps. If you need me to I can go take a picture of my spring and BHO for referance for you. They are out of the shotty at the moment but you should get the idea.

Thanks for the quick reply Hunter121.

Your description is nicely detailed.
No need to post a pic, I can understand what you're saying ... which is exactly what my plan is.

I am happy someone understands what the hell I am saying . Heres a few pictures for shits and giggles, maybe it will help someone else down the line. I also found the little string/dental floss/fishing line method to pull the spring down into place to be the best way to do it. Its still a PITA, but works.

Having just converted a Saiga-12 and paying attention. The long leg of the BHO spring goes to the front. (As installed at the Saiga factory Izhmash.) I noticed that you cut a notch in your BHO to allow the selector to be installed.

After the previous paragraph, I was bothered by what I wrote. I inspected my Saiga-12 that I had previously built. I installed the long leg of the spring toward the rear. The reason I did this was it was easier to grab with my tiny spring hook, and it looked right. I installed the spring before I installed the selector, so the spring ended up below the selector. The BHO works fine for me the the spring being below the selector.

How did you get the BHO spring to rest against the selector?

Heres a picture of the inside of my S12, hopefully it will clear any questions up. I never cut the BHO, it is all factory. I also had to pull the spring down with some fishing line so I could get the trigger pin threw the hole of the spring. The safety selector was installed before any thing else.

The BHO spring looks bent. Is it bent? Do you bend it if it is?

Thats correct, I made a little 'dog leg' at the end of the short end so it would stay on the BHO better. I am sure this most likely is not neccesary for everyone but I was having issues with the spring staying on the BHO with out the dog leg when I was trying to get the fire controll group installed. Basicly how I ended up with the above was this:

1. installed with short leg towards mag- Worked at first but after a few tries with the BHO it started to hang up the BCG and would not let go even with pulling the BCG back.

2. Re-installed with short leg towards the rear/buttstock- Worked once and then the short leg slipped off the BHO.

3. Re-installed with the short leg having a 90degree bend(dog leg) at the end- Works great, has not slipped off. When I dis-assembeled for painting that little dog leg refused to let go. I had to take needle nose pliers and yank the BHO out.

To be honest if your worried about the way you installed yours, I would not stress it to much. All that matters is that it works and stays in place. Hell if I installed the damn thing upside down and backwords I would'nt care as long as it worked .

IF anyone thinks that the info/pictures I put up are misleading or is the wrong info please let me know and I will be happy to edit my posts. What you see above is what worked for me and it works very well.

The short leg needs to go to the rear. Currently I have it installed with the long leg to the rear and it is binding. As soon as I find a roundtoit I will correct it.

Here is what I finally did with mine.

I actually bent a half loop to go around the BHO tab.
This way, I figure it ceratinly won't come off.

I also feel it necessary to throw a big +A1 to a couple other guys for some mods you see here.
1. The (very necessary) notch in the BHO lever when using the full retaining plate on the other side.
2. And the addition of a weld tit on the trigger bar to keep that side of the main trigger spring from sliding to the inside.

Thanks again for the suggestions and help.

(I moved this side's trigger spring out of the way for these pictures)

Now, why the hell didn't I run into this post before I started converting (read=fighting with) my IZ-132? The damned BHO spring kicked my ass for 2 hours until I got some string to hold the little bastard. God, I'm glad that's over!!!

+1. And next time I take mine apart, the BHO is getting notched so I can slide the selector in over it.

I'd have to see that, if it's anything like what I'm thinking it is.
