How do you keep the front end from coming loose on the new Excalibur takedown crossbows? After around 5 to 10 shots its loose and then you have to take the front end off, tighten up the bolt put the front end back on. Then it's tight again for 5 to 10 shots and then you have to repeat the process. How do you stop this?

No lock nut or crush washer?

There is a locknut. But the front end still comes loose after 5 or 10 shots. Then I have to take the front end back off. Loosen up the lock nut screw the bolt in a quarter turn and tighten up the locknut. Snap the front end back on and it's fine. But only for 5 to 10 shots.

Loctite should not be used at all. The way the mechanism is made, you will kick your own ass if you do use loctite. When you push the stirrup down to unlock, you are moving a fork that engages what looks like a flathead screw. That wedge shape that the fork engages will guarantee periodic adjustments in the future. That piece that looks like a flathead screw has a locking nut that needs to be tightened well. After adjusting the stirrup and riser should have no play. There's a bit of a delicate balance that needs to be done at this point. A bit too tight and that blue bar that disengages the stirrup will be impossible to move. You want the mechanism tight enough that the blue bar does not want to move until you smack the stirrup down.
If you've done it right, you will push down on the blue bar, give the stirrup a smack and the stirrup will fall away. Make sure you use a metal lubricant on the shaft, on the wedge of the screw head and the shiny chrome like locking pin.

I understand all that. I just don't like having to mess with that every 5 to 10 shots. I like the old front ends way better. Put 1 or 2 bolts in depending on which excalibur it is. Tighten up and shoot. Way easier to deal with.

Mine kept coming loose as well until I adjusted the engagement a bit tighter and added some grease to the engagement points.

Mine limbs keep coming loose every dozen shots. I take it off tighten the screw thing and the lock nut.. then shoot more.. and the limb loosens up again. Any other suggestions...?? Or just throw out the $1500 I spent on this junk... ? My second excalibur that is falling apart

I have a 360 TD and a 400 Suppressor TD. Both do not come lose. When I got my first TD bow it was acting like you describe until I did what I described.

I did exactly what you said, twice today.. when bow is taken apart, should the handle/part u step on, be extremely wobbley? I'm wondering if that could be the culprit. It seems unusually loose
I had to tighten down a couple of bolts on mine, but now it snug and has been for over 50 shots.

I love my Excals but really do not see why there is a need for this "special" takedown feature..it's a PITA in my opinion.
Had the same issues as others posted here..just give me the darn T-handle wrench and a Allen bolt or two for the front end and I'll be just fine!

If I was going to buy my crossbow over again, I would not get the takedown version. I didn't realize how simple it is to "take down" a regular Excalibur.

No question about that. As of the departure of the last two president, Excalibur was going the route of TD for all of their bows if not most. It really is a marketing gimmick in my eyes but it is handy if you get into the routine of using it.
