Anyone know the origin of this rifle?
Before I bother AI with a message, does anyone happen to know the origin of this rifle? Perhaps it might reveal that there are a handful more PMs in the wild.
I don't know if I am reading the serial number correctly, but it appears to have a rather unusual serial number. Firstly, it is crudely marked with a letter punch, and I read it to be 92 PM 665 where 665 would usually be in the range of <90 PM xxxx> rather than <92 PM xxxx>, and it would also be 0665 not 665.

I think that it was originally a PM rifle and altered - badly - to make it look like an L96. I don't remember any of our L96's fitted with any sort of flash eliminator. But I might be wrong about that, given that they were in my time, from 1985 to obsolescent in 2012 or so. And how would you fit the foresight block if it had a flash eliminator fitted?

The scientists as Shrivenham concluded that the swiirly flash eliminator served absolutely no function whatsoever in respect of accuracy, bullet stability or flash supression. There was something else too but I forget what it was.
The same applied to the swirly flash 'hider' fitted for several years to the little SA80's. A frill, of not a total fraud. It was fitted because it came with the Daniel Defence (? sorry if I'm mistaken there...)) sand coloured UOR (urgent Operational Requirement) handguard kits that had built-in picatinny rails. But you get to the point that the more you CAN put onto the rifle, the more the crunchies want to fit! Pistol grip, torch, wire cutters, kettle, cooker, Jump start leads......... and..... and...

Accidentally deleted my comment after #3 which I was trying to edit. Here's a copy below:
It's one of the later PM variants with the single chamber muzzle brake. These brakes came in about 1989 or 1990. The Irish contract PMs from 89-91 or so tended to have both L96 iron sights and swirly flash hider just in front of the foresight. Various AI brochures from that time suggest that they actually had quite a fair bit of freedom as to what spec of "commercial" PM they could offer.
I’d like to get my hands on a lesser known contract PM rifle. This one is particularly interesting.
The swirly flash hider is a left handed M18x1.5 thread and the foresight fits over a 19mm shank. That doesn't leave much of a shoulder on the barrel for the flash hider to butt up against. I managed to pick one up a while ago and just took a closer look. Looks like you could either make the threaded section of the barrel longer than the threaded section of the flash hider and mate the end of the muzzle with the step inside the flash hider, or keep the threaded section of the barrel short and butt the flash hider right up against the foresight.

Barrel harmonics? They can increase muzzle noise, upset barrel jump.

Not all of us Peter, I prefer the M4 at least as light as they first made them. Specially as I get older.
