I believe the OP's photo is a Mk2 BAR introduced in 1993.
The Browning BAR sporting version is certainly a distinct and separate rifle from the military BAR M1918, but its design is the result that started with John M. Browning. His grandson, Bruce Browning, was the driving force behind today's BAR. A large team of automatic firearms experts at the FN factory in Belgium also played a key role in its development.
This group of FN automatic rifle designers, led by Marcel Olinger, began serious work on the project code named "Carbine 66," with full scale development and testing done throughout 1966 in preparation for an official 1967 product launch.
The original prototypes had the distinctive scalloped receiver, which all early BAR’s had. The trigger group assembly was reliable, but complex. The design required the disassembly of the buttstock from the receiver to remove the trigger group. BAR’s at that time came with your choice of a right or left-handed safety, but they were not reversible. All calibers were built on a long action length receiver.
Initially the civilian BAR rifle was totally produced in Belgium, however in the early 1970’s the assembly process was transferred to their new facility in Viana, Portugal and is where the BAR continues to be assembled today. Contrary to what some have said, the BAR has always been made in Belgium and assembled in Portugal from the beginning.
Not well known to many was a special project in the early 1970s to produce a BAR version just for law enforcement. This rifle featured a slightly modified, high capacity FN FAL magazine and was chambered in 308 Winchester. However, the rifle never made it into production.
I bought this MK1 Type 2 BAR in 1987 to use deer hunting....didn't get one that year with this rifle. I think it's a great looking rifle.
The BAR has evolved slightly for over four decades.
Rifles manufactured between 1968 and 1978 are usually called Type 1 rifles (referred in the Browning Armorer Manual as “old” style).
Rifles manufactured between 1979 and 1992 they are often called Type 2 rifles (referred in the Manual a “new” style), however these rifles are very similar to the original Type 1 models.
