'Converted' BHO


Recommended Posts

It's not to hard once you figure it out. To get the spring in I ran a small piece of string through the hammer pin hole and looped it around the spring. Then just pull down on the sring untill you get the pin through it. Once the spring is on the pin pull out the string and just push the pin the rest of the way through. It was much easier to do on the 7.62x39 than the 12. You will also need to grind down on the button for the BHO. Its too long when you have your rifle converted. It will get in the way of your trigger finger.

There is a problem with the BHO after the conversion... as you all may well discover, or HAVE ALREADY discovered...

 

The TAPCO G2 trigger group is made for a Receiver WITHOUT BHO... and the hammer pivot area is made to fit FLUSH in the NON BHO receiver... to put the BHO in, I had to grind away the right edge of that area, the part of the hammer that the pin rides through, and the hammer pivots on...so that it was shorter there, THEN I could get the BHO back in place... obviously you only need to grind away from the end of the trigger sleeve or whatever you want to call it... as much metal as the THICKNESS of the BHO unit itself... like a 1/16th of an inch or so...very litlle metal... but enough to get it all to fit back in...I used the OLD hammer as a guide as to how much metal to take off... measuring the width of that sleeve till they were the same...

 

Then I replaced the BHO, and the spring, put the FCG parts all in, and the pins...etc...used a small spring hook tool to grab the spring and pull it up and over the nook on the BHO itself...

 

all done... nice as you please... functions flawlessly!

By all means put it back in. You will be glad you did. I used the dental floss method described above and it was easy. Also while you have it out it's easy to shorten it a bit and round the end of it off. This will make it more comfy to use and you can have a last round BHO that some people have been whining about needing and not having. All you have to do is push up on the button with the left side of your trigger finger (assuming you're right handed)while squeezing off the last round and it catches the bolt and holds it there for your mag change. Insert mag, lightly hit the charging handle to release it and you're ready to rock and roll.

+1 on what Indy said about grinding the hammer axis on the right side.

Yea, I put the BHO back in when I did my conversion. It was the hardest part of the conversion because I couldent find the posts which covered grinding down the hammer sleeve or which direction the spring sat in there.

 

After a few hours of frustration, I was finally able to find the post that had a really good cad drawing of the internal assembly showing the spring and describing the dental floss method. I followed That method exactly as described and ended hours of fiddling with one simple method that took five minutes.

 

I was so happy that I got it all back together, that I think I even reposted the picture and the method, or maybe bumped the post up. I cant remember.

 

I would suggest reinstalling the BHO just because its a neat little feature. And you will feel pretty cool after its all back together.

 

Good Luck!

There ya go!

 

I bumped it up for ya, but I think the picture is long gone now. Sorry.

 

I think we can make another picture for you from memory if ya want. Anyone good with thier cad drafter software?

 

Or I could take a picture of the inside of my reciever on the BHO side as an assembly referance.

 

Let us know how you are doing with it. There are plenty of us here who can easily walk you through it.

Thanks Pistonring8;

Yes, I would like to see how the spring is attached......Also, I haven't been able to find the binder posts locally yet, are they the best bet for the cross piece??...

I shoot left-handed so actually the BHO might be a moot point anyway...If it held the bolt open after the last round, it would be much more useful....Still considering it tho (While I'm waiting for my stock to arrive).................

I recall seeing a product developed for the AK and Saiga that acted as a last round BHO. It involved modifying your magazines with a little metal tab that would actuate the internal BHO on the last round. It was a bit pricey, very involved and kinda silly.

 

Like some other people have said before, hold up on your BHO when your shooting your last round. Or if you want to know when your empty, listen for the snap.

 

:lolol:

 

I hope this helps, Good Luck!

another option is to make a "tool" to acutally hold down the spring while you intall the pin, if the string/fishing line idea doesn't work well for you (it didn't for me). I made a "V" notch in the end of a popcicle stick to push down on the round part of the spring, holding it concentric with the pin hole in the reciever so I could put the pin in.
