Ultralight Ultralight Rifles

So, if I'm not mistaken... the NFA Poly LPK is no longer available... has anyone found a suitable lightweight alternative?

Can we add relatively inexpensive as a qualifier? That NFA polymer LPM was a real bargain compared to any lightweight, piecemeal alternatives I'm aware of.

I haven't yet, but it might be worth contacting them (NFA) to see if they have any plans to make the poly LPK again. Since re-opening they have had very little of anything...

For anyone looking for a Shaw portless barrel, they are now showing in stock on Shaw’s website.

This is what NFA replied to my question about when the poly lpk will be available again:

"Hello
Thank you for reaching out to us.
Currently, we're working to add more and more products to our website but at this time, we only have a backstock of the items we had already produced before reopening.
Stay tuned for new products and old returning products, hopefully soon!
Thank you for your time."



I wonder if some of the lpk parts could be 3D printed effectively?

Thanks for checking, good info.

I think that's a great idea (printing parts). Even if the trigger/hammer part didn't work, since, for example, I've been using metal triggers, the key pieces for me would be the other small parts. Add to that a printed end plate and there would be some weight savings and money savings over anything else available.

I'd think a printed version of safety, pivot pins, etc., could be plenty strong.

Radical is using polymer LPKs. I wonder where they get them.

What's an endplate? Just kidding, but I just held the spring in place with a set screw. I might have tapped the hole, can't remember. Probably got this idea from @packgoatguy ?

For whatever reason, who knows, I haven't gone that route. I do have a CF end plate from Smoke Composites that's pretty nice.

I just ditch the end plate entirely. I don't bother with the spring either. The rear takedown pin has been tight enough in all my builds... its never fallen out or anything. But the way I designed my stocks, the carbon tube actually extends into the Solo300 an inch, so the upper/lower wouldn't come apart anyway without removing the stock/buffertube piece.
