Diana 48/52 Bullpup

Thought id share a few pics of my recent project gun. It started off as a standard UK spec 1990 48/52 in 5.5mm, and ive spent the last 6 months picking away at the conversion....

The cylinder is now sleeved down from 28 to 25mm, running a lightened TX200 piston (200gr) and the stroke has been shortened to 80mm. Following this the SCR was out and despite fitting a 3mm restrictor the cycle still felt a little slammy, so the TP was sleeved down to 2.8mm, giving an SCR of around 1:1000. 

Not what most of you guys are accustomed too I know! But it now makes a very comfortable 11.5fpe on a Titan No6 spring at 15mm preload, and recoil is no more than a gentle nudge in the shoulder.

The trigger linkage is of a pull type design using a lightweight 2mm carbon fibre rod, so all of the 1st and 2nd stage feel of and adjustment of the original T01 trigger is still present.

The barrel was cut to 10", and the shroud has a 1 peice baffle with 3" of chamber that reflexes to the rear. The 28mm ID Ali tube was powder coated at home in textured black using a Tribostatic gun.

The stock is American maple that has been ebonised, aged and oiled, and the final action finish is a custom mix midnight gold Cerakote.

Its all far from perfect, but its my first full conversion and stock, so on the whole quite happy how its come out 😊

Thanks for looking 👍


 
Thank you gents appreciate the kind words! 

Gave it its first run on paper this morning, and no surprise but it absolutely sucks at the bench! Very difficult to get any sort of consistent hold with out gripping to firmly, and equally as difficult to get a decent rest going on.....not to worry I only hunt so standing supported shots are where its at with a pup anyway 😁

I made a recoil damper picatinny bipod mount a while back though.....

.....will find a method to fix it to the pup and give that a try perhaps....fingers crossed it helps to improve its manners at the bench....
 
I've owned the RWS48 and the RWS52 as well but what you've done to this springer has been nothing but "simply marvelous" and very different. The bull pup design makes it very unique, well thought out, just plain "purty" and I hope it's a shooter as well.
YES!!.....Right on the 💰💵‼️
