Okay so I got most of the way through Angel Breeching my longshot and I was pretty happy with it, untill I realized it would be nearly impossible to pull the bolt back now. I've looked through a lot of threads about it, and it seems like some ppl re-glue the nub on from the stock bolt, and re-use the bolt sled, but I've tried super glue, epoxy putty, and gorilla glue and nothing has held under the pressure of a [k26] spring.

I also tried a hose clamp, but (a) it still slid out of place and ( it got in the way of the clip feeding.

Finally, I tried soldering a steel cube (about the size of the stock bolt nub) to the brass, and this actually held, but broke after 5 shots.

The only other idea I have is to get some 5/8" brass (1 increment larger) and maybe cut a 'tab' out of it that could be bent up, and then used as a contact point for more steel soldering, but I don't want to buy a whole foot of brass (in a size I have no other use for) for a small reinforcement if it won't work.

So what works for you guys? How do you prime your angel breeched longshots?

This is a problem I've had as well. I've found that the longshot brass breech mod guide on SGNerf ( http://modworks.blog...-mod-guide.html ) helps a lot, but the bolt is still breaking after 10-15 shots.

[Zorns Lemma]

The method outlined on SGNerf's page will give you the most contact surface for adhesive. Then use an epoxy resin, especially if you can get one formulated for brass. Roughing up the brass to increase friction and surface area through score lines will also increase the strength of the bond.

If you are using a 17/32" brass main barrle, then you can actually full enclose the bolt in plastic for a crazy amount of surface area. This is the method I use on my Raiders and Longshots:

Elaborating on What Zorn's Lemma said above, you would basically be drilling out the stock barrel/bolt and putting the brass one inside it. If you can't get another bolt, I have a few suggestions based on mine and a friend's experience with the standard Angel breech.

-Make sure that the nub has the proper amount sanded off of it. If it is slightly too far or too close to the brass, this will put unnecessary stress on it. Basically, if it is attached to the bolt sled without being glued to the brass, it should be touching the brass, but not pushing against it too hard.

-Really rough up the brass and the nub. What my friend ended up doing was using a cutting wheel on his dremel to put some grooves in the brass before glueing the nub on.

Try fishin' glue.

And if that doesn't work, you could always perform the pullback mod, and take the pressure off the bolt.

Very useful advice from all.

Perhaps i can also give some input from my experience in successfully getting the bolt attachment point to hold permanently even with stronger springs. I currently swap between 14kg - 18kg custom aftermarket springs for my brass breeched longshots.

I use specific customised foam darts which fit perfectly in 9/16" brass barrels, so i also had to find a lasting solution to the bolt attachment issue.

I tried every glue avaliable at my local hardware stores... super glues, fishing glues, various 2 part epoxy glues etc. Even with the larger bolt attachment surface area, all of the tested glues still could not provide a solid attachment for more than a dozen shots.

Until i tested the Selleys Araldite Super Strength 2-part epoxy glue. It is an epoxy glue that requires 72 hours (yes, 3 full days) to cure for maximum bond strength.

Here is a product link for reference: http://www.selleys.c...th/default.aspx

In addition, i also use a customised polycarbonate shotgun grip which helps balance the load stress to prevent the twisting flex that tends to occur during one-sided charging handle priming.

So far, after many games and extensive test fires over the past few months, the bolt attachment piece is still holding strong without any signs of weakness or breakage. So it looks like the Selleys Super Strength Epoxy Glue was an ideal adhesive for this application, matched with the larger bolt attachment surface area and perhaps the customised shotgun grip.

Maybe you can try out that epoxy glue brand if you can find it at your local hardware stores, see if it works well for you.

wow very helpful replies all. The double half-pipe technique on SG nerf's mod looks like a perfect solution. Too bad I already chopped up my stock bolt for just the nub. Anybody got a spare stock bolt laying around heh.

I may be a day late and a dollar short, but this breech eliminates the boltsled, and the priming handle is attached by a bolt, not glue.

I have one of his longshots with the same breech. The first ever one actually. It has never broke and Is very sturdy. Once you get use to priming it it is very comfortabe.
