Hey guys,

I've been taking a gander at the Crypto stripper lower/upper kits that utilize AR15 parts and have been considering buying it and moving my AR15 parts over. Just looking for some assistance to determine what else I will need. I have an old CORE15 AR15 gas/carbine length I purchased 13-14 years ago.

Wanting to keep it non-restricted, I know I will need a new barrel - What about the gas system? Will I be able to utilize the current gas system from my AR15 to do this, or will I need something different? Aside from magazines, is there anything else I will need or won't work from my current rifle?

Thanks
 
It would depend on where the gas port is on the new barrel. Same distance from the breech use the existing gas system. Different location, change the gas tube. Whether you will be able to use the existing gas block/front sight base will depend on the diameter of the barrel you have, and the diameter of the new barrel. Another factor is how your original gas block is attached, and how the new barrel is set up. Cross pins vs clamp-on.
You will probably find that the selection of available AR barrels is a bit limited.

I appreciate the input, just realizing this may be a tad more daunting than just putting some lego together lol. Good starting point though, thank you.
 
You probably don't need to remove the restricted barrel from its upper. Muzzle unit, and gas block come off to the front. You might want the barrel nut - it will follow other parts off toward the muzzle.
For your project, might be an idea to get the receiver set while you can - there could be a real run on these - and start searching for the barrel. Once a barrel is in hand, you will know what is needed for the gas system. A clamp-on gas bock is a LOT easier to install than a used one previously attached with tapered pins.

This.
Much easier to just grab a new gas block. The standard ones are like $30 - $40. Clamp ons are about $60.
 
You will use everything from the donor gun except the front pivot pin and it's associated spring and detent. Everything else will transfer over. Bolt, recoil assembly, trigger, grips. You will need a non restricted barrel and a new gas tube, you may be able to reuse the gas block if it's a clamp or setscrew design but a new block is cheap and one less thing to worry about. Most non-restricted barrels are not going to use carbine gas anyways, more likely mid length gas for 18.6, and rifle gas for 20+.
