Weighed the parts to power the Trijicon scopes. If you end up sending you IR Hunter, REAP-IR, etc in for any repairs, firmware upgrade, etc., they will upgrade your battery compartment if it was manufactured before a particular date. All being produced now have upgraded battery compartments.
We sat down and started crunching numbers on force exerted by a certain weight, however there are too many factors that affect the numbers and cannot be rolled up as a definitive value because of the different factors. Those factors include cartridge, bullet weight, firearm weight shooter form, suppressors, muzzle brakes, recoil differences, accessory mounts, cables, etc. We calculated straight line general forces exerted by particular weights listed below, which are valuable, but not definitie due to other factors in the construction of the scopes.
Many are shooting battery caps with different batteries or external batteries and adapters with no issues. Other may have failed parts with external batteries and adapters, or scope failures due to poor design that has been remedied if your scope goes in for repair or upgrade and all new scopes. I'll leave it up to the buyer to decide.
I also received some information on an issue that Trijicon will address if needed. If you have any issues with installing batteries or they fit really tight, look inside your scopes battery compartment and see if there is excessive glue on the walls of the compartment.
Here are the approximate weights using my Pact digital scale. All weights are in grains and I converted also converted to ounces for a better perspective for some.

Long battery cap NVO - 549.7grs = 1.256 oz
Short battery cap TCT - 302.7grs = .692
UNV external battery adapter - 519.2grs = 1.187 oz
UNV dummy CR123 - 92.5grs = .211 oz
UNV cable connector approx. - 32.5grs = .074 oz (I added just a basic connector because this adds to the weight and depending on how the user mounts or attaches their cable it can add additional straight line or lateral forces)
Factory cap - 72.8gr = .166 oz
16650 battery - 610grs = 1.394 oz
17500 battery - 443.8grs = 1.014 oz
CR123 battery - 253.3grs = .579 oz
UNV kit - 644.2grs = 1.472 oz (does not include weight of battery, case, or cable, just what attaches to the battery compartment)
TCT kit (Mark II & III) - 1190.3grs = 2.721 oz
NVO Mark II & III kit - 1769.7grs = 4.045 oz
Mark II & III factory without extension, two CR123's - 599.1grs = 1.369
Mark II & III factory with extension and three CR123's - 1111.5grs = 2.541 oz
