Standards for firearm specifications on gun pages

[AdAstra2009]

The standard on most pages is as follows

==Specifications==
''(1949-present)''

'''Type:''' Assault Rifle

'''Caliber:''' 7.62x39mm

'''Capacity:''' 10, 30, 40-round box magazines, 75-round drum magazine.

'''Fire Modes:''' Safe/Full-Auto/Semi (600 RPM)

However some other pages include this information but they also include weight, length, barrel length, muzzle velocity. Personally I do not believe in including information (besides the years of manufacture, type, caliber, capacity, and fire modes) . When you add information like weight, barrel length, muzzle velocity, and other items like that it becomes too encyclopedic and imfdb is not a gun encyclopedia. The original 5 specifications provide a snapshot ;and can help identify errors in a film as well.(like how years of manufacture can identify anachronisms, etc.)

Thoughts?
