Dear Everybody,
Thankyou for all your responses, I did get ****ed off and felt attacked, over what I thought would be a fairly simple question, what is it!
Now I have calmed down, and re read everything I can see that I can seem like an arsehole. My comment that I'm an engineer was not intended to put any body down, I've been mis-quoted a bit, and my only interest was to see what this rifle is/was once, maybe nothing.
I purchased it for parts for a $100's seemed cheap to me, for a gun that other than missing a bit off the end, is recrowned and like new. I was told 2boxes of ammo, it is as tight as a drum. There are a lot of these in Canada, all exactly the same, obviously someone made them.
I'm am a crap photographer, read little interest. In trying to get close to show the detail it blured. I gave all the diamensions, there is no bedding, and no packing. The guy who sold it to me keep the parts he liked incase, and gave me the old crap which looked good to me. when I started puting it together it did not seem to fit correctly.
Some relieving of the stock had already been done, I did not get all the parts, I've since got a ring relieved the handgaurds and I'm doing a few other things to it, like fitting a L1A1 flash hider, making some heavy metal rings/sight blocks to try and quell any harmfull harmonics.
I brought the gun cheap, it didnt look right, I took some measurements, and ask some questions, I thought no biggie. I didn't want to cut up something I shouldn't, so I thought I would check. Sorry it got so out of hand. I am now modifying the gun as a shooter and a experimentation platform as I am now happy to modify the hell out of it, no remorse.
I still think the barrel is a bit heavier in places, than normal, if so good, if not I think I'll try the carbon fiber approach, seems like a good candiate. Best wishes to one and all.
Reards Ian
