DAYSTATE AIRWOLF BOLT
« on: October 02, 2017, 08:06:13 PM »
Any thoughts on why the bolt on my Daystate AW would have blown through the block?

If your talking ... Cocking bolt getting blown out the back of receiver ?
You had the cocking lug either unscrew itself or it got sheared off by excessive rearward cocking effort fatiguing it.
* have to remove receiver from air tube and have a look  ;)

I own a MK-3 & Airwolf so know there systems well.

Sorry I haven't been back for a few days as I have been doing some research  . There are only a few ways this can happen. One is the gun fired with the bolt in the open position and or wear and tear over time. After posting what happened on a couple sites I found both to be true. This is a design flaw. If the bolt is open? Why can the gun shoot? My mag was damaged by 33 MK1 ammo. I was single loading 25.4 ammo

Even if the lug or bolt handle that lock the bolt closed in a PCP is strong enough to withstand the force of shooting the gun.... if the bolt handle is not locked down, so that the bolt can fly back when the gun is fired, that locking mechanism can shear off.... This is because the bolt, which has significant mass, is accelerated backwards by the same pressure that fires the pellet, gaining energy and momentum until the lug or bolt handle comes to an abrupt halt when it hits something.... It's like hitting something with a hammer, and can easily shear off the lug or bolt handle....

The moral of the story is.... NEVER fire a PCP without the bolt locked in place.... or the bolt can be propelled out of the back of the action.... unless there is something strong enough to stop it.... Engineering the bolt lockup to withstand the static loads is not enough....  :o

Having said that, I know nothing about the Daystate, so cannot comment....

 I would have drove this gun to you Scott for analyst.  Daystate don't want and are betting they won't here from me?
The bolt don't lock! It hit me in the face! I have the part that broke off!
So the gun will fire open bolt. At 3000PSI that's a problem. It's a design flaw. I didn't do that? but I bought it used.
Darren from AoA admitted its a problem.
Bob, really, This gun has you stumped?
HAHAHA

Please don't bite the hand that feeds!

I'm not a Daystate user, and I've only had one in my hand. I would not say it was under-built, but it was certainly lighter than I had been used to when it comes to airguns. That aside, the fit and finish was perfect! I have to assume the internals were as exacting. And for what it is worth, the gun was used, wasn't it? So unless you're very knowledgeable about airguns in general, figuring out what the pervious owner did with, or to, the gun, is conjecture, but the result certainly are not!

Daystate is not alone in being able to be fired with the bolt open, or not locked down.... it is very common (nearly universal?) in airguns.... The danger is that IF fired with the bolt open that something breaks and the bolt can come out the back of the receiver and harm the shooter.... The same danger exists in many common PCPs when guys convert them to larger calibers, and/or higher operating pressures, and do not check to make sure the locking mechanism is strong enough for an "open bolt" discharge....
