How to make a BB gun using a pen get a pen...take everything off of/ inside of the pen...get the case of it (the body) get a mechanical pencil...take the plunger out (the thing holding the eraser) NOTE: the pencil MUST be the kind with the plunger running all the way down the body on the inside put the plunger in the pen body (it should be able to slide in and out with NO problem) get 1-4 rubber bands, cut them so that they make a C shape (one cut) put all of them together so that they fit together...put the middle of the mass on top of the pencil plunger...stretch the rubber band cluster towards the bottom of the pen body...use glue or something to attatch the cluster there...wait for it to dry...then, pull back on the plunger, put a BB in the body, aim, and release the plunger...there you go, it shot... these can be modified
The number of BBs that make up 2.5 ounces depends on the size and weight of each BB. Standard airsoft BBs typically weigh 0.12 grams each, while steel BBs can weigh around 0.35 grams. To convert ounces to grams, 2.5 ounces is approximately 70.87 grams. Therefore, for 0.12-gram BBs, you would have about 590 BBs, while for 0.35-gram BBs, you would have around 202 BBs.
.25 Airsoft bbs can be good. Their weight is very good for accuracy and helps for a harder hit from the bbs. However, no bb is good if they are not high polish. Companies like Madbull and Matrix make good .25 bbs.

Unless you are talking about a metal bb gun, no. All bbs are standard unless metal. And yes, big bbs are stronger than small. Learn physics.
