First hand a target at the range you want. Then you clamp down the gun (or find a way to keep it still). You take 3 shots at the paper then adjust the left and right and up and down until you are happy with where it shoots.
an electric sight is a "red dot" sight that uses a laser to project a red dot where the airsoft bbs will go when you sight it it.
Which sight? most have a switch or rotational switch that can be turned off.
Yes, but you should have rail mount base attached on the upper receiver of your pulse R74 first.
Unless you have a higher priced or accurate gun, buy high end bb's and take the time to sight it in properly, a red dot or any optics does not do much for the gun.
Yes, a front and a rear sight.
There is no restriction on age for a sight in the USA.
Buy what you want but here are some suggestions. the SMK 6x36 35mm dayscope, red dot laser aimer, bipod, susat sight, acog sight, red dot sight and finally if you have £15,000 to spend, a BW thermal scope.

Do you mean DE M89? If your airsoft have a picantinny rail (MIL-STD-1913 rail/STANAG 2324 rail), it can be fitted with any accessories that is subjected to it. You can get this accessories at any airsoft stores.
Well, it depends if you are for accuracy or if you just want it to look cool. I go for both. On my gun I use a Laser (Pressure activated), a Red-Dot sight, a grip, and a flashlight. All of these combined makes a pretty awesome gun. Hope it helped!
The BSA red dot sight test measures how well a person can use a BSA red dot sight on a gun. BSA red dot sights are good for quarter and medium range targets.
