Machine Gun Tips & Tricks - Part 2

[colddrake80]

Interesting video. I've seen a semi-auto uzi disassembled and it is amazing how something with so few parts can do what it does.

[epicsr]

Nice and easy mod. I once read a book written by a Vietnam war vet, a navy seal, and he talked about increasing the rof on the m60. He said you could increase it by dropping in a coin between some parts. His outfit used to carry spare parts for the 60 too, because reliability became a real issue. Also, my experience is that one can increase the rof on an ak47, almost the exact same way as you show with the uzi. Just drop in a rubbery block behind the boltcarrier, at the back of the receiver.

[sidewindermack]

The Sterling end cap and recoil spring are round and the eraser is square. It may not fit right. I am going to try to find an eraser that is larger and try to cut a circular buffer from it. Most erasers I have seen are rectangular in shape and about the size of the one in the video.

[C2builder]

@sidewindermack The erasers composition and flexability is more important than the shape, if it's not a gum-type material eraser it will not work as well or reliably.

[claudiobenassi85]

Always the best. Take care.

[sidewindermack]

Hey C2, would this eraser trick work on a Sterling Mk4? If not, would you consider doing a Tips & Tricks video on the Sterling? Thanks!

[C2builder]

@sidewindermack It should work on any blow-back operated machine gun. I havn't tried it yet on my Sterling but may now since you brought it up.

[xekul]

this guy is my hero

[eric82a]

@c2builder I have a semi Uzi will this lil trick do something for my gun

[eric82a]

@ c2bulider

I have a semi Uzi will this trick do any thing if I try it on my gun

[C2builder]

@eric82a Nope. Won't do anything at all to speed the gun up.

[newin10]

i live in VA if i want a century arms c93 (hk 93 clone) what license would i need to get it? or can i just get plain gun permit ?

[C2builder]

@newin10 Certain States have different firearm laws so you need to check your States laws to see what you need. I'm not up on VA laws.

[tansit2344]

@newin10 I live near Richmond, VA. There isn't really anything special about the C93 sporter. You could have one shipped to any dealer, run through the instant background check and have one inside of a week. The only permits Virginia has are for carry of a concealed handgun. NFA regulated items are handled the normal fashion, registered transferable items, Chief LEO approval, fingerprint cards, plus one approved federal tax stamp. Paperwork (copies) must accompany the NFA item.

[9beckerful]

genius! i will definitely try this :D

[kurnellampdwarf]

I thought it was B :D

[thetimetohunt]

Can you do this with a AK 47

[C2builder]

@thetimetohunt No, two completely different recoil systems. The AK's are better controled on speed by altering thier gas systems.

[ermaslv44]

@C2builder can i do it with a danish madsen?

[C2builder]

@ermaslv44 Yes, same type buffer as the Uzi.

[ermaslv44]

@C2builder cool thx

[Leadfarmer337]

damn thats badass i subbed

[gooman989898]

cant you just get a stronger spring?

[C2builder]

@gooman989898 The sronger spring still has the bolt going the same distance forward and backward, the eraser shortens the distence and adds a additional rebound to allow the bolt to cycle faster.

[GunloverClark]

@C2builder in theory you could apply the same set up to a semi atoumatic ar 15?

2 question how do you afford to purchase all the class 3 firearms

Im certain you have your proper permets but is the cost of a full atou less if you build it from a kit?

[C2builder]

@GunloverClark It sounds correct in theory but you have to remember that the AR15/M16 is a gas operated closed bolt firearm so all you would be doing is restricting the gas system with enough force to cycle the rifle.

Yes, if you build the weapon from a parts kit it is cheaper. That is one of the plus benifits in being a Class 2 is being able to purchase cheap kits and turn them out at a good profitable working firearm.

[GunloverClark]

@C2builder good to know

i plan on going to trinidad state jr college and take their 3 year gunsmithing course and go into the wepons design buisnes

its my dream to replace the AR style platform in our millitary

[rugersix]

Cool vid! =) I guessed correct "B"!!! Enjoyed shooting a couple when I was in Israel last November!

[AdmiralNeeda]

Random question, but what do you do with all the spent shell casings? Leave them on the ground? And if you just sweep them up, how do you do that when you fire over dirt? Have you tried attaching a collecting bag to the gun? I read that the Russians did this to their AK-47 to keep the gun secret. Every casing needed to be accounted for..

[C2builder]

@AdmiralNeeda Yes I pick up all the brass and dump them into a 50 gallon drum then turn them in for cash once each year, usually around 300 pounds worth. The steel spent cases are usually just thrown away, no cash value.

[Crim15]

@AdmiralNeeda It's called 'policing', typical habit of cleaning up after each shoot. Almost everyone does it..

[coltI9II]

@C2builder kiwitedferny has just bought an Uzi, you may want to inform him of this nifty trick :). Good video, once again.

[BulletK1ss]

thats a really nice uzi, and a smart way of increasing the rpm!

and as always awesome vid! 5 stars!

[erkwit]

Before you listed the options I thought to myself, "add a silencer, heavier spring, or more powerful ammo." The eraser seems to increase the spring's weight/pressure and provide an elastic surface for the bolt to bounce off of. I imagine more powerful ammo and adding a silencer would also help, right?

[C2builder]

@erkwit More powerful ammo might have a increase but it wouldn't be noticable to human ears. Adding a suppressor wouldn't increase pressure and make the gun run faster. Yes the gun would be quieter at the muzzle end but the pressure in the chamber is still the same and would not affect speed of the bolt.

Good guesses though.....you get a cookie :)

[SecretTrollAccount1]

This is a cool video C2builder

[petrwarry72]

5*****

[JOECHOPYTACO]

Speaking of sub machine guns, do you have any Stens or MP40's. And uhm one more stupid question, do you have a Federal Firearms License ?

[C2builder]

@JOECHOPYTACO Yes & yes.

[milowagon]

Would the gun be any use at 700 rpm. The magazine empties in no time. You would need a wheelbarrow to carry your ammo! Great video, as always. Greetings from Scotland (no guns allowed) oh well!

[C2builder]

@milowagon Not any different than why gun designers made the Mini-Uzi, Micro-Uzi, Mac10, Mac11, etc.

[klesmer]

Your wife will skin you alive if you scratch that counter top.

[C2builder]

@klesmer It's my shop area....my zone.

[klesmer]

@C2builder Damn, Brother. You livin' in style! My shop bench is plywood, old plywood. 'Bout 40yrs old, seen alot of guns.

[C2builder]

@klesmer I'm installing the overhead cabinets and counters myself. Not easy to do in your spare time. Spare time....what is that?

[klesmer]

@C2builder I have been there and done that. I am dissabled now-sholders and back- but if I lived in your neck of the woods I would still offer to come by and help.

[C2builder]

@klesmer Thanks.

[indiodvdreviews]

do you have any mac 11's?

[C2builder]

@indiodvdreviews Two on order, hope to get them soon.

[MultiSr16]

hahaha dammit, it must be nice to have a FA uzi layin around the house to rub on... not to mention whats in the safe , jeez., C2builder is the MAN

[MegaRucker]

great stuff, more plse



[miltnxc123]

hell yeah

[coltI9II]

Another great vid :)

[hinz9303]

how many guns do you have?

[C2builder]

@hinz9303 That's classified. No problem asking though.

[MultiSr16]

@C2builder i got a secret security clearance, u can tell me, i have access to classified material.....:)

[C2builder]

@MultiSr16 Very well.......let's just say about 50 full-auto and about 20 semi-autos.

[MultiSr16]

@C2builder ahhhhh, so in other words, your friends call you SIR hahaha, thx for the info, impressive !

[klesmer]

@C2builder Folks ask me that question alot. I just tell them-not enough.

[Reynard13Fuchs]

Before I ever view the rest of the video, in reply to the multiple choice.

I believe choice A. is unreliable and can damage the firearm severely, B. increases the likelihood of jamming (FTF) and could cause damage. A lighter bolt I might say would be the best option.

But I'll see in the video.

[C2builder]

@Reynard13Fuchs All of the options given are up for debate but each has its points. Option C. is only going to get you that high ROF and you will need another original bolt to achieve 500rpm again. My point in showing these tips & tricks is what simple mods can be done with household items with no tools or machining the parts of the gun.

[Reynard13Fuchs]

@Reynard13Fuchs I realize this now, very nice video. I never thought of what is used in the video being a component. Took me by surprise. Thank you

[TheMRTIMBUK2]

VERY USEFUL AND VERY COOL

AND THANKS FOR ALSO MENTIONING DISADVANTAGES.

[jeffxl12]

won't the eraser help not to wear down over time. It is hitting something soft instead of the metal back?

[C2builder]

@jeffxl12 That eraser will long out live you or the gun.

[pau11111]

Very nice!! I like that you normaly use international metric system that everyone understand what your saying thanks for that.

Keep doing this videos the'r are unique on youtube

[SamEEE12]

Hey Jim, try putting a windscreen on your mic - that'll cut down on the wind noise.

[C2builder]

@SamEEE12 I'll try that.

[weapons4war]

excellent c2. i see that you do know alot about the ins-n-outs of these fine collections.

cheers! more plz.

[GoesWithTheNameOfGTJ]

Increasing rate of fire using a rubber eraser? Genius!

[ML4000]

cool stuff :)

[karamelles98]

The answer A if i am not wrong helps to reduce the rpm. I had heard that german machinegunners used to cut the recoil spring shorter to reduce the firing rate for MG42 and save ammunition. Could it be true? Btw cool video with a lots of useful  information. Thanks.

[C2builder]

@karamelles98 I don't think cutting the MG42 recoil spring will do anything other than cause jams. The '42 also uses the front booster cone to assist recoil and the balance on the spring for recoil would change.

Thanks.

[greenteen85]

The uzi guts are not unlike a stapler

[bosoxboy521]

didnt this serve in Vietnam, by MACV SOG units

[GoesWithTheNameOfGTJ]

@bosoxboy521 Yes it did. (atleast in Black Ops)

[Panzerwurfer]

@GoesWithTheNameOfGTJ Lol, black ops also has an RPK with a hooded rear sight and a carrying handle. Never use that game as a reference

[TheRunawayjew]

you sir are a genious ( ya my spelling and grammar are horrid) please continue with the great work

[191145acpcolt]

im thinking answer number b

[seanxvw]

C2builder does this process work on a M.A.C. 10 .45 ACP?

Thanks!!

[C2builder]

@seanxvw Yes.

[scodurh]

nic vid as always...thanks for taking the time to share

[TheRealTingAling]

ah sorry i didn't finish watching the video

[nbenicewicz]

Ok, now that I've seen how to speed up the ROF of an UZI, is there a way to slow down the ROF of say a MAC-10?

[C2builder]

@nbenicewicz Yes but thats another vid in the future.

[nbenicewicz]

@C2builder I await to see it. I hope it comes soon.

[SweStuff94]

hehe my gandpa did this in the army when they were bored. in that time they used swedish K subM. and if u took a exstra spring and inserted behind the first recoil spring. so going from 500/rpm to 1000/rpm. that was so fast so u had to tilt the weapon on its side or else the empty brass wouldet get out. and if u presst the trigger only one time (single fire) it would still go fullauto. and it wouldet stop fire until there were no ammo left in the mag :D

[tojoconfused]

C2b - I've heard the L1A1 (semi-auto FN FAL) can be modded to automatic with a matchstick. How's that done?

[C2builder]

@tojoconfused Never heard of that one and I doubt it would stay in place. Now using a paperclip, thats a neat trick.......

[sidewindermack]

Hey C2, Great video as usual! Thanks for posting!

[magicman2002]

Dang, it's amazing what you can do with simple household supplies and guns :D.

[SweStuff94]

@C2builder is ur uzi moded? i meen 900rpm is standar rigth? :)

[C2builder]

@SweStuff94 I think you are thinking about the Mini-Uzi or Micro-Uzi, which does run that fast in stock config.

[JackCarver10]

@SweStuff94 You're playing CoD, am I right?

[shinymarshtop2]

love it

[canadamonster]

i was right



[mrmezmureyz]

awesome guy...what tips you have for an MAC M10 45 ACP ?????

[mattinmo]

I dont want to toot my own horn but I knew it had something to do with double buffering, beep beep

[C2builder]

@edro20 True, a good example is the aircraft versions of the Browning 1919, had lighter bolts and ran like a raped ape. This trick is mainly to show what you can no without tools or perm mods.

Thanks!

[rippinreffers]

Excellent stuff as always. I personally find this really cool!

[AK74Man87]

That is a cool trick, now i want one. How much do you want for yours lol.

[QcHernan17]

Good to know. I actually thought in putting a stronger recoil spring. I don't know if you can actually find a stronger recoil spring, but I'm sure there's a way. :)

Would it work?

[C2builder]

@QcHernan17 Yes a stiffer recoil spring would increase ROF but I'm not sure by how much. Plus you would then need two springs so you can revert back to standard if you wish. This trick you don't need two springs.

[CasinAandC]

How do you become a C2/C3 weapons builder/dealer?

[C2builder]

@CasinAandC Too much detail to list here. Search online for "class 3 dealer license"

[TheCharlesis]

@C2builder could u teach me how to shoot a gun?

[groundzero94]

i have 2 of the black jack buffers for my uzi its 1.4 inches and goes in front of the recoil spring so it don`t keep the spring depressed but this is a very nice trick and you can adjust it to how you whant. and you can shoot hotter loads to increse the rof.

[C2builder]

@groundzero94 Yes, I have been using Blackjack buffers in my AK's as well. Really helps smooth out recoil and makes it easier on the shoulder. The Blackjacks were really made to soften recoil and not change the ROF.

[DaytonaRoadster]

..now if i can just get me an Uzi...
