I am thinking about building a very light weight .22LR AR for my son to use, he is about to turn 8. I took him shooting last weekend and he did very well but my dedicated 16" .22LR AR I have built now is just too heavy for him to keep up.
I have an ATI Omni lower and am thinking of buying a 20" CMMG barrel to cut down behind the gas block and have to crowned/threaded. I am thinking about chopping it down to about 10.5-12" or so. 
Part of me has issues SBRing a $30 polymer lower but like I said, I want this to be very light so he can use it effectively. What are your thoughts? |

He's not going to be 8 forever  Just build a 16" barreled upperQuoted:
He's not going to be 8 forever Just build a 16" barreled upperI know but he can grow into it I guess. Besides, maybe dad needs another gun project for this winter.

Why not just buy him an m&p 15-22? It's like 5 1/2 lbs. I thought about that, they are pretty light. My current rig weighs in at about 6.4lbs and I can get it to about 5.8 if I dump the red dot. (I've been making him learn on iron sights) Ideally I would like to get it under 5 lbs, maybe in the high 4's. |

You're not getting to 4lbs without EXTREME measures. Consider a youth model 10/22 or bolt action 22 until he grows into a lighter-model standard AR.
If you've gotta be "that extreme measures guy", consider skeletonizing the receiver, pistol grip and furniture. flat top and railed gas block, no handguards (give him a mitt), ultra featherweight barrel, keep mag size down to limit ammo weight. No buffer or spring to take down weight in the receiver extension. Possibly polymer lower and/or upper. |

Possibly polymer lower and/or upper. you can easily get under 4lbs w/ right selection of parts. polymer lower, for sure. no need for extreme measures. i do agree a good bolt action would be best OP, no need to SBR one at all |

It weighs in at 3.7 lbs or something. |

I was at the IL. State Ruger Rimfire match this last weekend.....had an 8 yo boy shooting my 4.5# AR 22 for all the rifle stages with no problem at all. The barrels weigh less than one pound which will be lighter than chopping down a 20" barrel you have shown.
You have a few options. Getting under 5# is easy with a TACCOM barrel or even a beyer barrel....getting under 4# is not out of the question if you go all polymer on the upper and lower. You can get close to 5 lbs using a 16" cmmg barrel and all polymer receivers. Tim |
| By the time you get the stamp back he will be almost 9 and will probably be able to heft the gun with ease. Now SBR'ing a spare cast lower for him to have later in life would be very cool of you. I just went through a similar process. Went with a light-weight off the shelf option and setting them up with SBR's for later. In my case weight and LOP were an issue so went with 10/22's with collapsing stocks. One a Troy chassis (I love that thing!) and the other in an Axiom stock (that thing is super light!). They really dig when you personalize it for them too with a special color or some other trinket. Good luck and have fun! |

Can you link a source for the polymer upper you suggest, please

Check out the bottom of this page on Tims website
look at last pic of rifle on scale I'm doing a form 1 on a Plum crazy lower to see what a 4 in sbr version will weigh lol |

nice groups |

This one is well under 5 lbs
PSA lower, buffer tube assembly, stock Taccom UL upper (AL shroud) and reliability kit CMMG SS bolt and group Geissele SSA-E trigger PA red dot with UTG riser Put the 1st couple hundred rounds through it last weekend, and the red dot was really nice but I wanted to get a bit more precision shooting out of it so I'm putting a Nikon P-22 and Aero Precision mount on it this week. That will bring the weight up to 5.5-6 lbs. And the SSA-E trigger...whoa, nice for shooting a 22 target rig

There are some nice rifles on this thread for sure. I'd just go with an M&P 15-22 and call it a day. Very affordable, reliable and you won't need a tax stamp to keep the weight down. I love mine, but I don't have high accuracy standards for it either. Sounds like you wont be happy with the purchase already... Buy Once Cry Once... MAHA |

Anyone know if a Model1Sales barrel will work with a CMMG barrel collar/conversion kit?
If so I may just go that route for a SBR and then send the 11.5" M1 barrel off to ADCO for a slimmer profile. That will be a lot cheaper than the CMMG barrel in the long run getting to the same length/profile. I am still thinking about the TACCOM barrel, my goal isn't 1/2" hole accuracy necessarily though. |

Mod1S will NOT work with CMMG's barrel extension. Mod1S uses Ceiner's BCG and the collar is sized to work with their barrel only. Go back and read Mod1S's product literature and you will see their assertion that their products are their products only. If you want to go Mod1S's, then you buy their BCG and Barrel. No mix and match. Ted |

I had the boy try out a couple different configurations tonight to see what he could handle best. There was a noticeable difference between a 16" barrel and a 8.5" barrel for him which equated to about 15-25 oz depending on the configuration.
I did some weighing and my polymer lower is 4.75 oz lighter than a AL lower of the same configuration. For comparison I used an ATI polymer lower vs. an Aero Precision lower. I wonder how much lighter a DPMS slick side upper is vs. a regular one. Anyone know? |

Mills, the DPMS Flat Top Lo-Pro Receiver is not light despite lacking the ejection hump forward assist and ejection port cover. The walls of this part are twice as thick as a standard receiver. The attraction to this part is its low cost, rigidity and dimensional accuracy. I'm sorry I can't give you a weight, but I have used these in my builds and I recall they are heavy. Ted |

Ted Thanks for that info, I'll scrap that part of the plan. |
