Sooooo! I must say that while this listing DOES NOT give me proceeds directly, I AM invested in this company for the long run.

I have paid money to haul in equipment and install said equipment.

I will be paid in new releases of gear ( mainly new design belt fed uppers)


We are working on a NEW 308 beltfed upper that will be 1/3 the cost of current models.

We have our .556 beltfed upper undergoing testing ( if you want I can eventually post that info up)


And I am the only person other than Paul that can give ANY discounts. ( it pays to know people)


We have our SOT and will be working towards supressors and new as of yesterday is that dead air wants to “ barter” with us so my original “ keymod and accessories post” is void and not needed.

Dead air has graciously filled that “ want” and we will be working with them in the future!

If anyone wants to check out our offerings please do! we have barrels that are out now that nobody else has in stock and our products are gaining a lot of attention.


We have a new lathe that was being delivered and funny enough cratered our outside wall and was crushed while being delivered!

But!


There are MANY MANY MANY things to come!


STAY TUNED!!!

Sorry. I was banned for pming an admin. 🤠

The lathe is in and running. The bfar-15 barrels are almost finished.

We will be starting the new belt fed uppers once barrels are done, once I get a couple of uppers in for testing we will be listing for sale.

The new 5.56 beltfed lower/regular mag lower will be the next prototype that will be headed my way for testing.

Feel free to check out Cryostructure.com for new items that will be coming in the next few weeks.

We are waiting on materials for the BF uppers now that the barrels are almost done. once we get the stock in we will be working on the fine tuning of the new equipment to get the ball rolling on the uppers AND lowers.

Y’all will be the first to see testing on these products. Trust me it’s been to long already imo but it has been a huge undertaking.

Half price beltfed uppers here we come!

OK guys it’s been a busy week. This is what’s going on.:


We started cutting HK-21* barrels Friday. We will be doing a batch of 150 and then sending them off to get chrome lined and coated.

Cold hammer forged, chromed lined with accessories will be $1000 or $800ea barrel alone.

We also have a new ambidextrous 80% lower hitting the site soon if he hasn’t uploaded them already.

We are doing presales of the belt fed uppers now as we already have the lowers available. If you buy a belt fed lower from us your spot is secured for an upper at $3300 ea.

All lowers that we sell can be custom coated to most colors that are available for $35 extra and offer coating colors for everything else we sell at an adjusted price OR you can send stuff in to be coated.

We have another mill, another lathe and a 200 ton press coming within the next month.

We just spent $20,000 on tooling in the last 30 days.

We now have three full time machinists working at the shop and have went from three machines to 12 within last year so it’s been BUSY.

We also offer standard AR lowers for cheap and we also build custom ar rifles that are guaranteed to be better than Daniel defense selling for $1500 in whatever color you prefer.

We have a DOD contract for M249 barrels that will also be available to civies in the coming months as well as new dual feed BFAR lowers that we are pumping out now.

We are 60 days out on the BFAR uppers (realistically). We had a hiccup with our compressor that set us back on our previous offering date because getting parts to rebuild it was a pain. (most everything in the warehouse is air cooled) everything was back on line this week and things have been going smoothly.

We also have a new grip extension for the belt feds and are offering them cheaper than competitors. ( for all you big handed/gloved shooters)

We have some stuff in stock that has not been listed on the website yet, but Paul is getting on that ASAP.

The ambidextrous 80% lowers are in stock and we have 24 available.

We have also completed AR 15 / AK-47 grip adapters.

We still have 3rd hole FA AR-15 jigs in stock that are available to class II type with SOT.

Thank you for coming to my TEDTalk. Stay tuned for more information as it becomes available!

If you are interested in anything or have any questions feel free to shoot me a p.m. and I would be glad to help.

I’m going to be helping him with marketing in the near future as his hands are completely full and he doesn’t have time.

Thanks again!

I forgot to mention we will be offering a service to build HK 21’s from parts kits if that’s your jam.
