Replacement bolt for sentinel

[Deeds]

Looking for a replacement bolt for one of my sentinels. Can't seem to find where it went, and I'm trying to get two of them ready for play as my wife wants to take her first trip out to the fields. Anyone have one or know for sure if a smart parts impulse bolt will infact substitute for the real deal?

i can confirm that the inlet hole and pin spacing is the same on mine, and that the bolt fits.
i haven't actually shot it for testing purposes.

I tried this a couple years back. I wish I could remember why I didn't end up using the Impulse bolt. I think it fit but didn't necessarily need it and stuck with the stock bolt

Well, two posts on the Internet is good enough for me. I've got one in order and I'll let you know how it goes

Mobile posting so can't edit photo titles. But a quick write up should suffice. As another forum post suggested, the shocker bolt is just a bit shorter. The air inlet is massive so it still lines up with the marker port, but depending on which bolt pin is used, you could experience roll back. Probably not that big of a problem for my sentinels (low air pressure so could only test with my Diadem) but with the shockteck bolt and bolt pin, it would sometimes roll past the eyes. With the shockteck bolt and stock bolt pin, it would work without a problem.

Now here's the real issue. Stock bolt in the Diadem, I was hitting 290+-2fps using 5 balls. I swapped the shockteck bolt in with shockteck bolt pin and stock bolt pin and was shooting 255fps....

So does it work...? Yes.
Is it ideal...? Depends on how bad you want to run a 20+ year old marker. I know I still will

Probably a smaller diameter so you're getting a lot of blowback/ air around it.

An old fix for rollback was to superglue an oring on the front face. So that'll at least fix that part.
