Shaznazabbadaz (author)2009-03-29

Im trying to make a p90 it has a removable mag that holds 30-35 rounds, it is in the same place as a real p90 but i dont know how to make the bullets fall into the chamber, any help here?

Use a long thin spring.

knexjay (author)Shaznazabbadaz2010-01-30

I have an idea! leave an open piece at the end of the mag put a light rubber band on the gun then put another mag under it pointing down and shake shake shake!

Shaznazabbadaz (author)knexjay2010-02-01

hmmm..............that might work, i will try that! exept i already destroyed it, im going to try to build it again!

the dunkis beast pistol on ki take a look how that works don't use bbs

depends, is the mag going to be on the top or the bottom? if from the bottom, then try something that pushed the bullet into the mag. if at the top, then the bullet should fall into the mag. are you using tan clips for you mag?

the problem is, is that its loaded in the same place as a real P90 so the bullets are pushed in straight up then they would have to drop into the chamber, i might use a mech similar to DJ Radios

Jared you would be able to use bb's and then curve the mag.

alright i will try that thanks!

jack691 (author)2010-01-26

T-Dog13 (author)2009-11-08

brentbrent (author)2009-09-26

idk i dont have it any more and the guns a year old you shouldnt expect much out of it

n00bkiller (author)2008-06-14

knexgunner do u need 2 brake the pcs

mettaurlover (author)n00bkiller2009-08-29

yes. OF COURSE YOU DO. rarely, IF EVER, when an ible tells you to break pieces you can use non-broken parts.

you go to pic library and browse upload the pics then when you comment you go to add images



phlorgan (author)silentassasin212009-07-03

Yeah about that, do you have to pull the trigger back to pull the ram and then let go of the trigger to release it?

BOO YAH!!! Range?

10 to 20 feet

Not bad for a semi-auto!
