After some years with WWII era sniping rifles, in the mid 1950s SB Arsenal instead looking forward, picked a design of the past as basis of the new rifle for snipers. A SB Mle. 25 rifle was cuted to half stock, was chambered to the new 7.62 x 51 NATO ammo, and gets a heavier barrel and a cheek rest, It was a standart weapon in the Army, Air Force, Navy, and Police well until the 2000s. Cheers.
Credits: Colosseum was the original artist of the KAR 98 (SB. Mle. 25) and of the scope. I tried to mimic Darth Panda's bipod for the L86 lmg. Thanks to both of you. Special thanks to Thiel: the "theory" is almost as important as the drawing!
I actually did not draw that optic - I think Nighthunter drew it for his Springfield 03A3 sniper versions. So the credit line should say "Colosseum, Nighthunter, & Reytuerto".
