Changing Butt Plate on Anschutz 1813 Match 54

[DKGambitUK]

Hi there,

I currently use an old Anschutz 1813 Match 54 and it uses one the original butt plates which only allows up / down adjustment on a sliding plate. It is not hook style butt plate.

I have been shooting prone for less than 12months on 25/50 range and noticed the butt plate has limited contact with mu shoulder due to an old collar bone injury where it didn’t set correctly so I have a slight lump / collar bone protrudes very slightly.

My thought process was to buy a highly adjustable butt plate that you find on many aluminium stocks and attach that to allow a better configuration / better contact with my shoulder.

My question is: Are these modern adjustable butt plates compatible with the Anschutz 1813, do you need any kind of adapter or do I have to invest in upgrading the stock to Aluminium? See attached as an example.

Any advice welcome.

By the way, I am shooting fairly tight groups the size of 5p piece at 25yds but I am sacrificing comfort and start to fidget half way through my box of 50 rounds and have to griz it towards the end of my session.

Yes, most modern buttplates are compatible with an 1813. I'm guessing from your description that you have an early-ish one*. Your 1813's butt is made up of three parts: 1) the plate that moves up-down and touches your shoulder ; 2) the base it moves on (should be silver-coloured on an 1813) and curved. 3) the carrier, a black metal plate with three prongs that gives length adjustment.

If you remove the plate you'll see the base is held onto the carrier with two hex-head bolts. Undo these, remove the base, and you can bolt the new buttplate onto the carrier; there will be holes/a slot for the bolts. On the carrier the bolts pass through horizontal slots so you can move the plate sideways/can to fit your shoulder and achieve the desired cant (or lack of cant) on the rifle.

Alternatively something like the System Gemini comes with mounting rods; just wind out the carrier all the way, slide in the SG rods and away you go. It will hold correctly still without the threaded centre rod.

*Assuming you have an 1813. I've met more than a few shooters who thought any thumbhole-stocked Anschutz was an 1813. That's not the case, an 1813 is a specific model made from 1980-'87: thumbhole stock + straight fore-end. Confusingly Anshutz marked the 1810 (cheaper 1813), and 1811 (prone-only stock) as 1813. An older rifle, or an 1811 would also match your description, but would require a different approach to an actual 1813.

Hey Tim ... as one that has multiple "1813" style rifles/stocks .... could you maybe post pictures of your "variants" described?

[Tim S]

I'll try.

I'm not very good with pictures.

So here is an early 1813 (or a 1613 barrel/action in an 1813 stock). Note the buttplate is adjustable for height on the curved base. The base is adjustable for cant and lateral offset. The hook is removeable, so this could be what yhe OP has: https://www.netgun.pl/lr22/sprzedam/105 ... -kal-22-lr

This is a later 1813 with the 4760 (aka 5 Screw or Armadillo buttplate): https://edelweissarms.com/anschutz-1813 ... sn-218xxx/

Here is an 1811, the cheekpiece has been mangled, but you can see how it is mistakenly described as an 1813, a 1411 made after 1973 or a 1611 would have a nearly identical stock. The buttplate is screwed onto the stock, and the screw spacing doesn't match a Supermatch: https://www.bonhams.com/auction/28729/l ... no-188328/

Here is a much older Match 54 Supermatch (possibly pre-dating the 1413 designation) that is sometimes lumped in with later rifles, the butt is much simpler, and a new one would have to replace the original moveable parts completely:

This is a very rough guide, as although the 1813 didn't change much, possibly because it was only made for seven years, there were at least five Supermatch stock variants before 1980, and several 1913 patterns after 1987. That's just the Supermatch, by my reckoning pre-1980 there were at least five Prone patterns, and eight Standards.

Tim - Thanks.
Seems like a lot of variants.

I bought this over 13 years ago when my daughter was in high school as a used "1813 Supermatch" - dunno know it that was true, but it has more of the what you describe as a 1913 pattern? She shot it in college to great effect (NCAA champ) but I've always wondered what it really is because of the newer buttplate attachent style. I use this gun with my junior shooters now....

The S/N on the receiver is 2969xx

Joel,

That's a 1913, the successor to the 1813. The s/n puts the barrel somewhere in the late 1990s or early 2000s. I think the stock may be newer though; I'd expect the 4-axis cheekpiece, and 3-rod butt carrier, rather than the 2213 patterns, but Anschutz did update the 1913 in the 2000s, so it may be the original. Whatever the exact age, aftermarket buttplates (like the MEC pictured) were much more common, and easily fitted than on an 1813 (or 1811, or other older Match 54).

Hey Tim - Thanks
