The tail cap threads on mine fit better than those on most of my lights. I understand that the precision of numerical control machining is mainly limited by thermal expansion, so it gets worse as the process is sped up.
This light was already heavily cloned. (eg what we are discussing here was never the original)
This doesn’t mean that cheaper clones can’t be made but generally the process seems to bottom out. (like with the SRK) I think the F13 lights probably bottomed out a while ago.
I use duct tape on my two Yezl t9s, because they have intermittent tail switches for electronic switch drivers, but now have regular drivers. The threads are anodized but not completely. It works nicely but eventually starts getting loose. Aluminum foil epoxied on lasts longer. I have some thin copper but haven’t tried it yet. I have a couple of very cheap SK-68s that I have junked because of the tail threads.
This is an ultrafire c 308 battery tube that fits but just looks stupid.I am pretty pumped to get this now and finally finish what I started.This light in shorty mode is awesome, now to search out 5+ amp driver.Thanks for confirming the fit Warhawk!
Thanks guys for all the answers regarding the tail cap fit. It seems there are a few people with loose tail cap threads but for $9 you complain too much! By the way mine has been lubed with silicon grease and it is BY FAR the loosest fitting tail cap out of over 100 lights I own. Anyway I have ordered another and hopefully this one is better.

Cautionary. Do you think a wrap with teflon tape would work, or would it eat up the tape?
I guess the threads aren’t particularly smooth since they ate up the anodizing.
It is more that the anodizing is thin. On the Yezl, it is more the rough threads. Teflon tape might be too thin to use on my twisty Yezl, but I think it would work on this one.
Just ordered two of them for my DST’s. Used the store points and it comes out to about $6.50/piece. Love 26650’s. It might look strange, but I like it.
Ordered two and got my first one today. The threads are very very loose in the end so there will be a fix somehow. The tube sayes XM-L2 on mine and it is one inside. Very nice beam.
No complaining, it´s a cheap light and we like to fix things in here so…
