build the absolute lightest PCC on earth

[nickbfishn]

That's my goal and its for my toothpick sized 10 year old girl. She shot an entire level II steel match with me this weekend and she used my PCC and loved it. However, towards the end of the day she was saying it was heavy.  Therefore, since she basically owns my heart, I want to build her the lightest possible carbine, money be dammed! (this could get ugly quick lol)  

 

I'm fairly certain I'll go back with a Taccom ULW barrel with only a foam hand guard and probably the simplest shoulder stock I can find, but what options are out there for lowers, uppers, charge handles, parts kits, etc???  I've seen pictures of receivers that have been milled and cut to remove weight, but not sure if that's custom work or store-bought.

 

Any thoughts and ideas are welcomed.

 

Thanks!

F-1 Firearms Has pretty much skeletonized everything about an AR-type rifle.  Don't think they have a PCC lower though.

Lead Star has skeletonized uppers, and lowers, but I think they are out of stock at the moment. Check their website.

Building an ultra-light PCC is tough to do and make PF without having the dot jump all over the place. And by ultra-light I mean a gun around the 5 and 1/2 pound mark.

Having said that, a ULW could be just the ticket for her. Even with a bit more recoil she could certainly learn from the experience. 

We're all glad she's giving it a go.

Would a skeletonized upper with a blow back action be a good idea?  I had thought about trying that but I was worried that I would be eating smoke and and soot.

Good point, b.

Unburned powder back in your face, too.

find a good polymer lower (NOT NFA)....Taccom ULW barrel with nut and foam. Anderson slick side upper with no FA. Not a fan at all on a blow back with a skeletonized upper.

I personally used a James Madison 80% polymer lower.......it's really light and very strong

I was thinking polymer lower. Did you have it cut specifically for 9mm mags?

Hmm, I didn’t consider that...good point.

no.....it comes ready for 223 mags.......I used a RRA insert for Colt mags

Not worried about Pf as she will only be shooting steel challenge...for now :-)

Ahh. I wonder if polymer + mag block = same weight as a billet?

Ah, bunny farts it is.

I say hunt around for the lightest lower you can find in the AR9 (Glock) platform, then top it off with a Taccom upper, a Taccom ULW barrel with foam hand guard, and a Taccom bolt with the mass weight removed. I'll bet you can get close to 5 pounds.

As Eric Von Zipper would say, "You will be her hero."

Hello: An upper like this will be a good starting point. It only weights 2lbs 3ozs with no bolt or charging handle. Another option would be a tricked out Ruger 10/22. My sons used one with a Nordic AR conversion and a Taccom hand guard. Here is the lightweight upper. Thanks, Eric

Well she was gifted a tricked out 10/22 from a complete stranger at the Alabama steel championship match this weekend. It was the most incredible thing I’ve ever experienced. I’ll text you a pic.

 

however, she’s convinced she wants to also have a “big gun” (9mm) like daddy ?

[nickbfishn]

Anyone know the actual weight of a mil-spec trigger group? Or perhaps the 24c?

[Screaminyz]

These are 13 ounces even being skeletonized, doesn’t seem very light for the price.


These are 11 ounces and seem to have good reviews to.

 The Taccom barrel and Anderson sport upper would be nice for steel challenge.   My 10/22 weighs in at about 4lbs  and is so much fun on steel.

not an ar, but a sub 2000 is real light. may not be what you want though

If we could get the trigger down to sub 3lbs then maybe

[nickbfishn]

So far with my research I think I can build one that will come in at 70 ounces. However, I may be able to shave a couple more with some ideas I have.

All my 24c triggers are in lowers but I weighed a new 24e.  Heavier than expected at 3.4 ounces.

[nickbfishn]

I was guesstimatingI was guesstimating About 3 ounces, so I wasn’t too far off :-).

[nickbfishn]

And I just got some great news that will make lightweight builds possible and very reasonable.I just got off the phone with Tennessee arms and they told me their polymer 9 mm lower will be released sometime next week. It will weigh in right at 7 ounces and they have already done rigorous testing and are offering a warranty against failure.I plan on buying a couple of them and seeing whatswhat
