Custom AR kit...

[ar15dave]

I am looking at putting together a custom AR kit. I will have a spare parts kit, magazines, BCG etc... for each caliber I am considering for the kit. Will make a custom carrier for it.

I am trying to keep this as light as possible. Keeping to that thought I was thinkig to keep the kit to three calibers. Thinking the AR will have one of them already assembled.

Here is the question: What calibers would you consider for this kit?

I was considering the following:

1) 5.56 (covers .223 as well)
2) 7.62x39 (can shoot AK rounds)
3) 9mm (One of the most popular ronds world wide)

Thoughts?

Thanks,

Dave

Broken shell extractor in necessary calibers.
Take down GI cleaning rod for hammering out stuck shells.
Sight tools and mini tool kit. Bore illuminator.

If you are going to carry a spare AR BCG in the field then you can probably skip those parts and worry about the lower springs and pins. A broken pivot pin won't shut you down but a hammer pin will.

Yep, I had planned to have a mini spare parts kit with pins and springs and such. Was thinging to have at least 1 BCG for each caliber. Cleaning kit will also be part of the kit. Trying to get as much in the kit as possible with as little weight as possible and cover the most popular probable calibers possible.

Once I have all the pieces I want I am going to design a carrier for it. Depending on the weight might make it MOLLE compatible and at least have a shoulder strap.

Am I misunderstanding this? You can't just change calibers by swapping BCGs, you need the right barrel, too... and that's going to require tools.

Is this some kind of bug out kit? If it is, load up some mags with each of the above calibers and hike around with it. You'll probably drop the 9mm and AK rounds as they're significantly heavier than the .223.

BTW, since you mentioned ARs, DPMS makes a few kits that have commonly replaced parts on ARs. They have one called a field repair kit.

Each cal would have an upper, bcg and 1-2 mags. Extra BCG for each. To change out all you would have to do is drop on the new complete upper for the new caliber.

Kid of a bug-out style kit but lets me go to ranges and on trips wih multipple calibers without having to look around for everything all the time.

Figured the uppers would weigh the most. That is why i am trying to keep the claibers to a minimum. only 203 of the most popular types

You chage claibers by swapping complete uppers with BCGs and mags. Thats it. Or at least the idea behind this. Quick and easy.

The obvious solution to your problem is to get a LMT MRP and than just carry a bolt, magazines, and barrel along with the torque wrench. It'll be much lighter than carrying 2 extra complete uppers, bolt groups, and magazines.

I'm still struggling with this - so you're talking about carrying around three different uppers? I don't even see how that's remotely realistic in a bug-out situation. Those things are heavy, and you'll have plenty of other stuff to carry.

I don't understand what you're trying to make... Are you putting together a Battle Kit for yourself? What do you mean by kit?

This. (If I am understanding the question)

2) 7.62x39 (can shoot AK rounds)
3) 9mm (One of the most popular ronds world wide)

The 9mm will need a block and full BCG. Also make sure the lower has a 9mm hammer (it will work with 5.56, but 5.56 hammers don't work as well with 9mm).

For the 7.62x39 I'd suggest 2 bolts (or one of really high quality)- skip the bolt carrier as it uses the same as the 5.5 (and they rarely go bad).

How many small parts are you considering carring? For how many rounds do you want to be able to support the rifle?

BTW don't forget a couple spare trigger/hammer pins. Lesser ones have been known to break on occasion and if they go out the gun is dead. They are small and light and can be a lifesaver.

Why not just do 223 and 22LR, you'll only need a blowback 22 bolt kit. What you save in weight from not carrying all the other gear you can carry other gear that will serve a better purpose, and you'll save over 1k bucks for whatever other gear you 'really need'

.223
.300 blackout- more performance than 9mm and uses the same bolt and mags but still performs well suppressed and subsonic
6.5- more power for longer shots.

First, uppers are not all that heavy. Especially if they are SBRs. There will probabyl only two in the kit at a time as one would be on the lower (yes it would be a registered SBR).

Spare parts would be minimum but picking calibers requiring minimum parts swap out. Swaping out uppers is much quicker then using a wrench to swap out barrels. Using a 9mm bolt that uses a standard AR hammer (stuff like that).

For this thread I was just wondering which calibers made the most sense for availability and versatility.
