Building a Lightweight AR Pistol that is Piston Operated

[sadclownwp]

If all you are going to say is gas impingement is lighter than piston, please do not comment.

Has anyone built anything like this before?

I'm looking at the following parts:
Kaiser Gen 3 receiver set (I know, polymer and titanium)
Faxon midlength gunner barrel 11.5 inches
Superlative Arms midlength piston kit
Some type of carbon fiber handguard
the rest of the parts as light as I can get.

I'm not deadset on the parts. I definitely want piston, because as a lefty, shooting a gas impingement AR supressed is not great.

I like the idea.

Buy a Sig Rattler???

I've shot them. They do not impress me either by weight or accuracy. I hope to build something better.

Some type of carbon fiber handguard

The PRI delta is designed to be piston-compatible, but I don't think it's the lightest handguard.

Interested in following this as a fellow lefty but too poor to do the same at this time.

Haven't seen any lightweight BCG that aren't very spendy.



Had you considered the Adams Arms piston kit?

Adams Arms does a LW Piston BCG

Wait a few months for the PSA JAKL?

But with the JAKL be light?

Well no parts I want are in stock anywhere except for the upper and lower... Perhaps I should just buy an 11.5 inch Adams Arms P2 pistol and call it a day?

I have one of these, RRA PDS. Functions well, like it because it is short. Not sure about being suitable for a lefty, I am very right handed.

That's a cool piece.

Update, ordered a bunch of parts from OpticsPlanet. Several days later, I got an email that almost everything I ordered that was said to be in stock was backordered.

I think I may just end up going with an Adams Arms P2 11.5 inch pistol.
