It may be that Heckler and Koch have changed the tolerances of the internal parts. You can't use A1 precision parts in an A2 with different internal dimensions.
Thats just what i've been told as I wanted to get one as a conversion training rifle for when the cadets start of on the A2

Why the rush? at the moment they still have the L92 A1 and it will be a while until the cadets actually get the A2, and then again if you manage to get a HK conversions kit for the cadets to keep you will be sadly disappointed, they are sort after items for A1 training. you could always ask the local CCF contingent if you could use theirs.

No sorry, I wasn't being clear, when we do the Junior Leaders course we use L-85A2's. Some people severly fcuk up because they never train with a 5.56mm weapon. Besides, the L-98 is crap. I've personally broken 2

Nope, definately A2's. To the best of my knowledge, we borrow them from the RAF Regiment. It is essentially a smaller refined version of infantry/gunner training.

To give a best "educated guess" to the original question:

The barrel extension (and by extension the bolt) was changed. One less locking lug perhaps?

The rimfire insert has to engage in (or at least go into) the barrel extension, and since this is now different, the original kits will not fit.

I have seen the insides of the A2, but I have not seen the A1 and the A2 side by side to compare. I also have not seen the conversion kit since 2002, hence the above is an educated guess.

Thanks Stoatman.

Now everyone is back to work (!) we might get some more detailed info. Change to the barrel extension would be a potential problem for sure.

Ive seen SCC L98's and RN L85A2's next to each other and taken them apart. The inside of the A2's are very guici in comparison But the bolt looks the same as for the L98.

And wow are the new HK mags better than the peices of shite the old style ones are.

When you say they are "gucci" in comparison, do you mean just visually better finish or are the guide rods etc revised - different, plated etc?

Get the calipers out then and see if they actually are the same or just "look" the same. enquiring anoraks want to know!

The modifications carried out are:

- internal machining to clear feed and extraction paths

- new breech block and bolt

- new extractor and ejector with spring

- new recoil springs

- new firing pin

- new cocking handle

- entirely new magazine made from pressed steel

- new gas plug and cylinder

- new hammer

- new barrel extension

- new barrel (LSW only).


The bold bids should do it. I would be very surprised if it was anything else.

stoatman hit the nail on the head, Give that man a prize. I am popping into work later and will take a few pics of the differances if anyone is interested.
 
#19
It is the hammer that is the problem - A2 hammers are have a raised portion on the top which snags on the .22 conversion recoil spring and rod.

The locking lugs on the barrel extension are not an issue because the kit only uses them to locate the barrel insert.

A further issue would be because the hammer is heavier and the hammer spring is stronger so the kit would not recock. The conversion kit bolt would have to be lightened to increase recoil force.
 
#20
Our .22 conversions went before the A2's arrived.

The .22 conversion was barred from use in indoor ranges due to a H&S issue.

No indoor range = no point in using anything other than full bore
