Straight Pull L1A1 Rear Sight Problem

[PaulR]

Hi,
I have an L1A1 from Anglo Custom and had the same problem with a creeping rear sight, but only after I'd lubed it. I took it off and cleaned out all the oil and that seemd to cure the problem.
Also found that the GGG Lithuanian Nato that Fred sells at the Range Office at Bisley ejects perfectly even after 100 rounds rapid. It's also very accurate, shot some out of an AW last week at 300yrds, and most , except for two pulled shots were in the V.

Hi DarylDiana

Interesting that you had the same problem after oiling. I've never done that to mine but it is something else to look at.

Like you, I've found the rifle to be extremely accurate at similar distances, more so with the SUIT sight.

I've not managed to find any factory ammo .308 or 7.62 that extracts consistently, that's why I only shoot homeloads.

Is that a British wood stock on yours and I have to ask what's happened to the carrying handle, looks like it's been bent upwards at the back, or is it a trick of the camera?

Cheers

Hi Paul,
Try the GGG, works very well in a number of rifles. Also found the RWS shot well, but a bit pricey at £98/100.
Didn't notice the carry handle angle, does look weird, fine on the rifle, though I don't use it.
The butt wood is original, off a friends SLR that he kept after swoping for plastic when the army changed over. Its beech and I haven't yet been able to find an original handguard that matches so have gone with a repro beech from the States, could be a bit darker but getting there with repeat BLO.
Left the plastic pistol grip , more practical and think it looks OK.
We need to get an SLR shoot together at Bisley sometime.

I've tried the RWS 155gn .308. Looks well made, is very expensive but still wouldn't cycle in my 7.62 or .308 rifles. I'm not sure if I have come across GGG, is that Mil Surp 7.62 or civi .308?

I've tried both of these and sold off the remainder when I found these didn't cycle either:





The ACR L1A1s are chambered for .308 which is meant to be softer brass than NATO 7.62 so should extract easier, however, there are other subtle differences between .308 and 7.62 such as shoulder angle which can affect head spacing. Interesting article below:

OK --- Let's address the oft-posed question "Are the .308 Winchester and 7.62x51 NATO one and the same?" The simple answer is no. There are differences in chamber specs and maximum pressures. The SAMMI/CIP maximum pressure for the .308 Win cartridge is 62,000 psi, while the 7.62x51 max is 50,000 psi. Also, the headspace is slightly different. The .308 Win "Go Gauge" is 1.630" vs. 1.635" for the 7.62x51. The .308's "No-Go" dimension is 1.634" vs. 1.6405" for a 7.62x51 "No Go" gauge. That said, it is normally fine to shoot quality 7.62x51 NATO ammo in a gun chambered for the .308 Winchester (though not all NATO ammo is identical). Clint McKee of Fulton Armory notes: "[N]obody makes 7.62mm (NATO) ammo that isn't to the .308 'headspace' dimension spec. So 7.62mm ammo fits nicely into .308 chambers, as a rule." You CAN encounter problems going the other way, however. A commercial .308 Win round can exceed the max rated pressure for the 7.62x51. So, you should avoid putting full-power .308 Win rounds into military surplus rifles that have been designed for 50,000 psi max. Reloaders should also note that military ammo often is made with a thicker web. Consequently the case capacity of 7.62x51 brass is usually less than that of commercial .308 brass. You may need to reduce recommended .308 Winchester loads by as much as 2 full grains, if you reload with military 7.62x51 brass, such as Lake City or IMI.

factory .308 generates more pressure than a NATO 7.62

Bisley L1A1 meet, that's a good idea. As far as I am aware, we have a friend of mine who has one, there are three contributors on here that also own them, yourself, Huntervixen and Dirtbag. Who else Have I forgotten?

Yes have been through all the discussion about .308 versus 7.62. Not convinced, I think it all depends on strength of load, and expansion/contraction characteristics of the case.
The MEN/DAG German and RG surplus also have hard extraction in my rifle. However the GGG which is new made Nato spec ammo is fine.
I've also tried Privi 145grn which is usable, just, but not as trouble free as GGG.
Haven't actually seen anyone else shoot SLR's at Bisley, though a few of the Imbal FALs.
How would we arrange a shoot? a Sunday would be good for me, but not till after 18th Nov. Daughter's getting married!

+1 for the GGG for me, very smooth extraction. My rear sight is extremely hard to move, so much so that I thought that I had to press a release button to get it to go. I use a scope but I haven't noticed movement in the iron sight at all.

Isn't the MEN fairly hot? I certainly notice a difference between that and PRVI (Blue box) in my Rem, it's much more snappy, does that make sense?

Someone at my club made homeloads for his FAL, they seemed good too. He had a Para Imbel with also suffered with extraction.

I like the idea of an SLR meet. I think a PR stage would be a good test Just need the 58 webbing now tongueout

Thanks Daryl, I'll have to look the GGG up when I get back, I'll be out of the country until the 4th December so couldn't attend anything until after then, also, it's getting a bit close to Christmas so I suspect it would be the New Year before we could round L1A1 owners up.

How much is the GGG per 100?

At the moment, if I was to use the maximum safe powder load of A2520, with S&B Primers, 150 gn Hornady HPBT it works out to approximately £0.50 per bang, or £50.00 per 100.

I see we have another L1A1 owner on the forum, welcome to the club and the forum, tell us more about yours Charlotte the Flyer.

Hi Paul,

I've just done a thread on my SLR, with a couple of pics.

I think I paid about £110 for a 200 round battle pack from Bisley in the summer. Does anyone know of any northern stockists, it's a fair drive to get re-supplied. I had heard a rumour that North West Customs were going to do it for their LMTs but I haven't checked that out. Can anyone confirm? my local supplier usually just has MEN which is erm problematic! I recognise the 'bang it on the wood of the firing point' that was quoted above. Tends to raise a few eyebrows when you do it. Do the LMTs suffer similarly? ouch!
