SL68 II Freak Boring Barrel

[The Great Equalizer]

I’ve got the same barrel as Darknite667 on 2x SL68-II’s. TyMcNeer made them. He’s also freak bored a bunch of BE Tigersharks for me. I highly recommend him.

All you need to do it get one of the old brass lined Spyder barrels and sand off the threads, remove the brass liner with heat to melt the epoxy, cut the brass insert down and reinsert the remaining brass.....works great as a Freak Barrel on the SL-68 II

I always wondered if a turned down TechT I Fit kit would work. But then I opted for the .680 palmers barrel an never looked back.

Was there ever 3D printed Widgets for these? Seems like that would be the cheapest easiest solution to rollouts.

[Darknite667]

I haven't noticed any cracks in the barrel after the modification. Seems to be holding up well.

[Ironnerd]

I have been wanting to do something similar, but am concerned that barrel would become too weak. Any issues with cracking?

[Darknite667]

I don't. when I bought the barrel it was already turned down to fit the SL68-ii by a previous owner. I just had the freak bore modification done to it. Also if you end up trying this method of freak boring make sure that you recess the insert deep enough into the barrel to avoid having the front of the firing bolt catch the back of the freak insert and pull it out of the barrel into the breach. Food for thought.

Remember what threading it was before having it turned down?

[Darknite667]

If I am not mistaken I believe it is an old 1 piece all american barrel, yes. I added pictures of the complete marker and close up of the freak locking O-ring slots for reference.

[Sottyman]

What barrel did you use? Just like an old 1 piece all american?

[Darknite667]

I had an airsmith from the pre ransomed version of MCB freak bore and add 3 evenly spaced external oring grooves into a smart parts barrel that was turned down to fit my Sl68-ii (the oring locking method sounds similar to what you described in option 1). It works quite well for holding the freak inserts in place.

I am the type of guy who puts CCM 86 grips on PGPs.

I wanted to do that to the PGP I owned a couple years ago but couldn't ever find a T2 frame for sale.

Time to get the calipers out, and maybe run by the local proshop to check if they have any 98 backs. That being said, I do kinda like the idea of a stock-ish looking barrel. Who knows, I'll end up spending WAY too much time and thinking WAY too hard about this lol

[Flounder]

You just meed to make sure the pump handle fits over the barrel.

IIRC freak backs for Tippmann 98 has a shoulder at the breach end of the barrel, i.e. the insert goes into the freak back from the front end, much like on an AGD spec twist lock freak back.
If there is enough meat on the thread end of the barrel, to smooth it down for an SL 68 II, that should do the trick, regarding the prevention of inserts being pulled by the bolt.
