Item Relisted! FS/FT US Solid 30L Liquid Nitrogen Dewar

[The Stoic Noble]

US Solid cryogenic liquid nitrogen dewar tank. Comes with insulated cover, and two specimen canisters. Standing time for this tank is about 255 days. Great for specimens or experimenting with LN2. It costs approximately $50 to fill. Most welding supply shops can fill it.

$400. I'm open to reasonable offers and trades. Trades could include: Handguns, rifles, Surefire Scout, ammo (12 ga 00 buck 8 pellet) 9mm hollow point, Manticore Arms parts for the Tavor TS12, Criterion 5.56 or 300 blk barrel, BCM upper receiver or parts and silver If you have something else interesting send it my way. It's worth a shot.

You have me curious now. How is LN2 used for barrels? This specific dewar is used for freezing specimens (bovine or blood) by placing the vials into the metal cannisters and lowering them in. Or, as simple storage of LN2 for experiments (science, culinary, ice cream, fun etc). A barrel could fit, but it would have to be short.

Its a metal stress relieving process

By stress relieving barrels it has been said will change barrel harmonics thus ; achieve better groups and to ease cleaning of copper fouling..... was an added bonus.......... I have only sent one off to have this treatment '700 rem'.......... -300 then warm up slowly to 300 then cool. 'repeat', if I recall correctly.....
the treatment claim to me was true but having only one firearm treated I can't say this is a norm
