Anyone Seen These Drawings Before?

I have to say that the direction of the axis screw never bothered me. Was there an EMER designated 'correct' way I'm bound to ask.

Pete, I cant state or indeed quote the designation on the hinge pin situation. But as you know yourself, when they left the factories originally. That is how they were assembled.
And indeed, although the positioning of the H/Pin screw has absolutely no effect on the Rifle Operation when firing.

As Armourers though, It DID give a visual indicator. That the 'User' had taken the rifle apart (Which was forbidden) & may possibly have 'tinkered' with the Internal components!.......
I have observed this on quite a number of occasions, as I'm SURE you have yourself? That observing this visual indicator regarding the h/Pin screw assembly.
Upon taking the Trig Mech housing off the rifle concerned. A VERY Dangerous situation was discovered!....You will be perfectly aware of the 'Matchstick under the sear' Scenario!!!
Some idiots who performed this 'trick', forgot to remove those sticks after an exercise. & there rested a potential situation for lethal consequences!!!....

We all knew that it was done on occasions, & we all knew the reasons why. But nonetheless, it WAS forbidden. BUT, the Crunchies still performed this little 'trick'!....

So the 'Visual indicator' regarding the hinge pin screw positioning. Did have an important part to play in being the 'Right' way round under 'Normal' conditions.

And as you also know, we all get used to seeing what is 'Normal' don't We? As a Human failing (?) we are resistant to change! As we both feel, if it aint broke. don't fix it!....

Back to Scope mounts, I had totally forgotten the ones used by National Parks and Wildlife, I do their annual inspections in my area and they use three different brackets........if

(Well thats new, this posted itself before I had completed typing) .....I remember I will take pic's next time they are due in.
The L1A1 is their preferred weapon for Airiel culling, complete with case catchers of course.

We use deflector plates mounted above the ejection port to deflect the cases downward away from the rotor blades. .308 cases can do quite a lot of damage to $50,000 composite rotor blades! Semi-auto shotguns (Benellis are very popular) with buckshot are also used for some culling operations, and we use rubber deflectors that still allow access to the cocking handles.

When the FAL's and L1A1's were sold in NZ for civilian use, the Police required dealers to remove the safety sear, grind the safety bent, and fill the safety sear slot with a welded-in steel washer. Most of our cops had been through basic military training and were well aware of the matchstick trick. Although the safety sear performs an important function, the lack of it makes no difference to the use of the rifle or the life of the components, despite literally thousands of rounds fired through them. The only time I have had to replace a hammer or sear is because some clown has tried to do his own trigger job.

In a tail wagging the dog way Woodsy, I had to modify my Straight Pull L1A1 Safety Sear to make the new production .22 conversion kit work with my rifle.

These new kits were designed for the US market, so lack the safety Sear trip on the bolt group. I cut away the arm from a spare sear in mine, but it would have been just as easy to remove the bent from a spare hammer I suppose and just let the connecting arm glide around the hammer.

While we are on the subject of (and getting the thread back on track) I thought I would dig out an old custom L1A1 scope mount and try it on a rifle (very quick phone pics mounted on one of my Lithgows this morning), I posted pics of this mount a few years back when I was attempting to discover its origins. It would seem that this is yet another civilian gunsmithing mounting system, probably UK pre 1988 ban in origin.

How it will stand up to fullbore I don't know, I intend to shoot it with my .22 conversion kit initially.

I carefully examined the mounting blocks and they are very well made (purpose built for Parker Hale mounts with their pin and hole system, (probably a very good idea for the L1's recoil), they appear to be Tig welded from underneath and brazed on too, but would they stand up to regular use, I doubt it somehow..

The ocular end of the scope looks a bit far back for comfort to me if you're going to use it for full bore. Been there done it - or rather it done it to me!

[mrclark303]

Evening Peter, yep I think we have all been smacked in the eyebrow by our scopes at some point if were honest!

The worst case I have seen was a young squaddy (use to his L85) who got thoroughly "scope kissed" despite the warning by a Springfield A4 Sniper, what a mess, just not prepared for a .30-06 kicking!

It's staying purely .22 conversion kit for now as it's a rather nice mount and it would be a shame to shake it to bits.

[Peter Laidler]

Same as when we let the press loose with the new SA80 carbine, together with a load of other carbines of the past as a comparison shoot. 2x Stens, Sterling, .30 carbine, little SA80 shorty carbine etc etc and then, the biggie........ the No5 carbine. I did tell them to hold it tight, sight in and squeeeeeze the trigger. The girl from the Daily XXXX didn't quite take the briefing to heart and got a real smacking from the recoil and many swear words followed. To be fair, she took it all in good heart bless her!

On your sight (thread 46) I'm pretty sure that you won't have enough elevation to zero that to the trajectory of the .22" bullet MPI because the graticle acts as a foresight. Could be wrong of course

[mrclark303]

Planning to zero her in tomorrow at 25yds, she's roughly bore sighted, I'll report back with positive ... or negative results!

It's an old cheap scope that used to be on my Spikes Tactical AR, we will see..
