The result was first known as VERSAbus-E but was later renamed to VMEbus, for VERSAmodule Eurocard bus (although some refer to it as Versa Module Europa). [ 3 ] At this point, a number of other companies involved in the 68000's ecosystem agreed to use the standard, including Signetics, Philips, Thomson, and Mostek.
Acknowledging shortcomings of the MOE systems, Magpul drafted M-LOK as a new and improved mounting standard which was released in 2014 replacing the existing MOE slot. The M-LOK rail specification included metric dimensions instead of imperial , and utilizes a T-slot nut capable of only 90-degree rotation, reinforced by thread-locking fluid ...
The UIT rail, also known as Anschutz rail, is a standard used for mounting slings and other gun accessories in competition shooting, and is essentially a T-slot track shaped aluminium extrusion profile accepting attachments in the form of T-slot nuts, or similar.
The military standard, MIL-STD-1913 "Picatinny rails" date from the mid-1990s and have very strict military standard dimensions and tolerances. The Picatinny rail has a similar profile to the Weaver, but the recoil groove width of the Picatinny rail is 0.206 in (5.23 mm) versus 0.180 in (4.57 mm) of the Weaver rail/mount, and by contrast with ...

Not only did the V engines provide over 3,000 hp (2,200 kW), but being single-crank with the consequently lighter engine block (over the dual-bank design) gave a better power-to-weight ratio. [11] The engine is a four-stroke turbocharged oil-cooled design, with the oil being cooled by water in a heat exchanger, and the water cooled in radiators.
