Introduction: P90 With Horizontal Magazine

Picture of P90 With Horizontal Magazine
Well this took a little longer than expected, but if you knew it was coming you probably were a litttle worried about the outcome. Not to worry though as you can see I used KGB's P90 and built it thanks to a guide from the Knextremist. I referenced the way that Dr. R had built his model when considering where the mag should be on the gun.
So what we have here is a shooting P90 replica with a horizontal magazine (just as the title suggests). Your probably bored of reading this wordy intro so let move to stats...


Shooting replica
looks good
expected range of 30ft
(tested with one rubberband got 10ft)
Reliable magazine


Long reloads
Trigger is, well, not my favorite...
More trigger issues
Not very comfy handle
Pulling the ram back is a bit challenging (friction issues)

Overall I think this gun is very promising and I will  continue to work out the remaining issues. I  think that even though I based this off someone elses P90 that this is pretty unique for the gun and is a much better replica than my QCW failure. I hope you like this and please leave a comment to tell me what you think about it.

If you hold it backwards it would look like a marines gun from starcraft 2 :)

JonnyBGood (author)die potato2013-08-31

That's a weird looking gun, in a backwards sort of way....... =)

AMAZING JOB but only 1 thing: Y U NO POST? I hope you do it is a 5* worthy build.

JonnyBGood (author)megustatrains2013-06-12

It's being posted today! No worries man. I try not to show anything I'm not going to create a full ible for. If you like any others from the past leave me a comment and I'll try to post them when I get some time off work.

megustatrains (author)JonnyBGood2013-07-03

JonnyBGood (author)~KGB~2013-06-28

Well, thought I'd seen that awhile ago in the forums. Well then........continue doing what you're doing then!

~KGB~ (author)JonnyBGood2013-06-29

Whoaaaa. favorited and subscribed. This is a STRAIGHT UP BEAST!!!!!! i like the looks of the whole thing, and the horizontal mag, too! But, if i may, here are some links for an internal pusher mag which you can modify:

JonnyBGood (author)CODawesome2013-06-05

Alright, thanks! Thanks for subscribing too. I'm thrilled that you like this. I'll look into your internal pusher mags for the it as well.

AMAZING!! it would be awesome to post it, I'd build it immediately

JonnyBGood (author)Knex.X2013-06-05

Well thanks! I'm planning on posting this tommorrow on my day off along with the Competitor III and the Competitor 1.2. I'm was pretty happy I could pull this off.

This looks FANTASTIC! IT IS AMAZING! I am totally favoring this. Dude, you did a fantastic job. I would love it if you would post! Pleas do! This is simply wonderful!

Can do. Glad you liked it though I spent quite a bit of time on it. =)
Checked off something on my list of things to do. Make a gun that you like.

Since when did you not have a gun that I did not like? I am just a person who prefers models, and this one is great. =D

Well I guess I feel that this one is more interesting for you since you're a model gun maker. Just so you know I'll post it after I get a big spontaneous project unloaded. It involves over 1,000 knex and a 50 inch tv screen, those two together equal awesomeness.

Well, yes, it might have more appeal to me, as opposed to a concept builder, but that really changes nothing. Wow, that new project sounds awesome. =D

Yep referenced the King of Random if you want a sneak peak.

What? I am not sure I understand...

My bad. Take a look at this video to see what I'm up too. I finished a prototype now I'm creating a second revised version.

Ah, I see. I'll get to that video soon, but I have school work to...well, on. XD

Yep and I have work to work later so it's alright, I'm pretty sure you'll like it.

O.K., good. =D

Johnhall14 (author)2013-05-19

Nice,not sure I like the mag release but I guess it works =D

JonnyBGood (author)Johnhall142013-05-20

Somewhat... As long as you don't hold this upside-down you'll be alright.

SumRndmGuy (author)2013-05-18

Definitely worth posting...thats BA

JonnyBGood (author)SumRndmGuy2013-05-18

Thanks! I will as soon as I can.

sandroknexmaster (author)2013-05-16

Looks nice!

Thanks! How's the ball machine coming?

Finished! But I didn't start filming yet, so it will take some time before I post the vid. And I'm also waiting to enter it in the knex contest.

Figured you were waiting for the contest. Glad it's done though, can't wait to see what you created this time!

Thank you

Vaetheon (author)2013-05-16

Very cool!

Vaetheon (author)JonnyBGood2013-05-17

You're welcome

dr. richtofen (author)2013-05-16

Nice, looks great! How does the trigger block work though?

JonnyBGood (author)dr. richtofen2013-05-16

It works like the one in Red's Welrod MKII. Did not like the trigger to much in that gun either. No offense to Red of course.

XD, I am with you on that one.

dr. richtofen (author)JonnyBGood2013-05-16

Ah, okay

nerfrocketeer (author)2013-05-16

pretty cool!!!

JonnyBGood (author)nerfrocketeer2013-05-16


knex dude 2000 (author)2013-05-16

I love it! i especially like how the guns handle has flexy-rods around it! Great work!

Well I did base the entire gun body off of KGB's P90, so I can't take to much credit for it.

JonnyBGood (author)2013-05-16

The video shows me loading my P90, I never had so much trouble getting the mag positioned before I made this video.
