So I resealed my FWB 103. Gotta say...... Easiest,most simple,straight forward rebuild I've ever done. I've worked on several different pistols both spring piston and pneumatic including: Dianas 5,6,lp5,10's....plenty of old Webleys...HW 45's....Gamos...HW 40's.....Crosman pumpers....etc... nothing compares to the simple, elegant,sensible FWB 103..such a pleasure...and what a great pistol it is. Even discovered a feature I didn't know it had in that the grip can change it's angle!!
Just too cool..... If only every rebuild could be as straightforward......Happy in Detroit.
