The counted foreign parts that your SLR95MB has are in bold. Non-bold are parts that your rifle does not have:
(1) Frames, receivers, receiver castings, forgings or stampings
(2) Barrels
(3) Barrel extensions
(4) Mounting blocks (trunions)
(5) Muzzle attachments
(6) Bolts
(7) Bolt carriers
(8) Operating rods
(9) Gas pistons
(10) Trigger housings
(11) Triggers
(12) Hammers
(13) Sears
(14) Disconnectors
(15) Buttstocks
(16) Pistol grips
(17) Forearms, handguards
(18) Magazine bodies
(19) Followers
(20) Floorplates
That's a total of 15 parts. If the receiver was stamped, you'd also have to include (4) because the trunion would be a seperate part from the receiver. As it is, the barrel mounts directly to the SLR95MB's machined receiver. Have confidence my friend. 15 is the correct answer.
