So the hilti gun cartridge will be rigged to fire a millisecond after the main cartridge - I like it.

Coudn't it be simplified if instead of using a second cartridge (the hilti) you simply bled off some gas from the barrel of rifle. I'm surprised that someone hasn't already thought of that. Oh they have, and some cretins have banned it already.

Well, I'm relieved to see the idea hasn't been rejected out of hand!

I'm talking of course a manually operated add-on - anything automated by firing the rifle would make it an SLR of course. My thinking is that if both the VZ.58 mech and a lever release mechanism is legal then so should this be.

The Hilti gun gas cartridge is a good idea, if cumbersome/fiddly and expensive. What about a CO2 bulb or similar?

Sounds like this might have legs...

I had a similar idea (but a CO2 powerlet based system).

I was wondering, though, whether it might need HO approval (if the lever-release and MARS systems did)? Might it be considered "easily modifiable" if an electric system (too easy to make the firing trigger it?) Would it even be permissible to add this to a held firearm (that presumably is already described as a "straight pull" rifle on the FAC) without bouncing it through an RFD?

won't you have to move your head/hand quickly and have no one behind you to avoid the nails when the hilt fires

I did a system using a 3ltr dive cylinder with a hand operated 'blow' valve to operate the bolt on an AR before, pain in the arse to carry, but for range use, was good fun, until certain members of the club took a dislike to it and banned me from using it.

I would imagine FEO approval would be required at least - but let's concentrate on the mechanics first! At the end of the day, it's not an automated system and technically less 'ready' than lever release or the MARS system. Just exploring an alternative.. until we lobby for the return of SLR.

your in the wrong club ! come and join mine, you will be nurtured and encouraged not to mention surrounded by similar eccentrics!!!

There could be medical justification for this too. I have mild arthritis in my shoulders and hand cocking is a pain in the neck.

Medical justification counts for nothing otherwise some would still have semi-auto rifles. There was a one handed stalker who tried to use that reason for retaining his BAR at the time of the proposed ban on such rifles. The BDS would not support his reasoning and neither did the NRA or so I am lead to believe.

Sorry, I didn't mean FEO justification per se; just a reason to pursue the project.
