My son's M4 Cristmas gun build
« on: December 23, 2015, 08:14:13 PM »
Well, he's 13 and has shown he is safe enough with my M4, so time to give him one of his own.
I'm starting with a Rock River Arms lower receiver and adding a complete Bravo Company 14.5" M4 profile upper.

First of all the mag release goes in.

This build will be a simple, close to the military gun so he can familiarize and get some good muscle memory going from an early age

I liberally use oil during the assembly. On the gun, my fingers, itchy spot on the top of my head somewhere and who knows where else as the build progresses

Next up comes the pinning of the trigger guard

Then the ever pesky front pin retention pin and spring. It is said to be the most difficult part, and may well be, but I just take my time and it works out fine

Oh, I use a chunk of wood, today a piece of 2X6 with a rag wrapped around it as my bench for the couple of times when I have to tap a pin home.

Now, the trigger and hammer are built up

The rear pin is held in place with a plunger and a spring which resides in the pistol grip

I am using a G.I. pistol grip since it's smaller diameter will fit his hand better and it's a real Armee piece

The rear buffer spring tube/stock mount captures both the pin and spring that retains the rear pin and the buffer and spring retention pin. SO it just takes some care and balance, and yes if your name is Don, you will lose the spring once or twice and put the stock nut on backwards, but what the heck, that all makes for good training!

I fitted the back with a magpul stock, and used the newest MP 30 rounder, then slid in the carbine length rail system with some rubber blocks, topped it with a magpul flip-up sight and this thing became a shooter.

I build a rifle for my girls 12th b-day, kind of a family tradition at this point. I only have one to go & she has already made requests of what she wants. The older two are now asking for pistols as the next step. So what next a scatter gun after that?

Nice build Don, I'm sure he'll love it.

Any chance you want to post the parts list for this build?  I am new to these guns and considering building rather than buying.  But if I build one I want to know at a minimum I have all the pieces before I start.  You make it sound easy ... but I bet that comes with experience.

Flip up sight is on backwards. What're you gonna put on for an optic? And that'll be a nice Xmas gift.

What Bobby said but here's the basics

Stripped lower receiver (part you will need to do paperwork on most likely)
Lower Parts kit with grip
Mil spec buffer tube carbine length mil spec w/ spring & buffer
Mil spec stock of your choice
Assembled upper of your choice with bcg & charging handle
Rear sight & or optics & front sight if upper didn't have it built in such as Dons A2 (I'm fond of these for first build myself)
Magazine

No way! Really?

Got me!

No optic...Has to learn the same way the rest of us did...iron sights.

Might do better on the sights, this Mag-Pul is the only one I could find

Yes really!  :D

Nothing wrong with learning on irons, however a simple red dot would be useful. No need for an ACOG or variable power scope. Nothing wrong with the MagPul sights for a starter. I HIGHLY doubt he's going to get the carbine hot enough to melt them.

I agree, start building. Good luck finding the parts you want right now. Christmas has hit most places hard. A lot of stuff is "out of stock"

Nice setup Don.  Why a 14 inch barrel, just curious?

You can get full kits from midway and brownells.

I also like to put tape on the lower when I drive in pins to keep the finish nice.

Can't add much but if you guys build or work on them I like using a formed block that kinda hold it in place as I fit other parts. Sometimes a magazine block in a vice is nice for holding it for tweaking.

Guess my build will be up next, just need a 12" gas tube (OOS everywhere)

So question for the masses.    My step son, ( 8 ) his father bought him a smith & wesson mp15/22 for Christmas.   I bought the boy a daisy rider last year for Easter and he can't even manage to cock it on his own.   How should I feel about this?

Well the Smith and Wesson is a definite upgrade from the daisy unit.......... :)

Sorry, couldn't help myself you asked about "feelings"......

My kids have shot since about that age. They never had BB or pellet guns and went straight to 22LR Having them grow up on the farm we always had "range days" where we went out and I monitored all ammunition. They were allowed to shoot one at a time and we went thru all the steps from loading and operating safety to clearing the weapon. I was always the person who handled the firearms between kids and safety was the priority. If it is a controlled setting there is no issue.

Edit: Also worth mentioning is that they all memorized the NRA gun safety rules before ever handling a weapon.

8 years old for owning their own gun is pushing it but OK.
I don't think they are GTG to use it unsupervised.

For a season (Literally) I would let my boys shoot their rifles as long as I was there doing something. The next year I let them go off on their own with the guns

As they have said, at that age supervision is a must. It depends a lot on the individual child and their capabilities as you already know. Take him out shooting with just his gun and do some training. Safety being 1st priority of course. Get a few mags and just load one round in each. Go through the drill over and over. Clear, load, get on target, safety off, finger on trigger, fire, safety on, drop mag, clear.........

Some folks think I'm nuts for teaching my girl about guns and talking about safe handling at 3 years old. I know she don't get the whole concept at that age, but I don't make a gun like the forbidden fruit. She knows she can go with me to shoot when she wants, mom is always there to help watch her of course. I usually sit in a chair and shoulder the gun. She stands between my legs and pulls the trigger. She also knows that she can't touch a gun without daddy's help. I have tried a few times to get her to take one from me and she won't. I make sure it is clear beforehand and I would not actually give it to her. Her reply has been the same every time. "I can't take that silly, you have to help me". Another thing I will not have in my house are "toy" guns. In my mind there is no such thing. A gun is a gun. The main thing is enjoy the time y'all spend together training in safe gun handling and teach him to respect it.

Dave, every child is different and the consequences of the failure of the child to heed the rules are catastrophic.

I began to teach my girls at 5&7 respectively the 4 rules.

1. every weapon is always loaded
2. never point a weapon at anything you do not wish to kill or destroy
3. never place your finger on the trigger until you are on target and ready to fire
4. Always know your target and what is beyond it.

Now they are not excited about shooting like I wished, but they absolutely know the rules and I trust them around weapons at 10&12.

Kids today don't know how easy they have it. When I was young, I had to walk 9 feet through shag carpet to change the TV channel.

If it was and we are still talking about Square D or the DR or my gun build or CIEMR, or whatever this started as, I don't remember whose kit. I pick them up from Aim surplus a few at a time...

I only have one so I have no need to color code I guess. Maybe I should buy different magazines then I can build a gun to match.   If the magazines are on sale of course
