Feets / Collection / My build Upgraded/Replaced HK barrel
Just installed an HK threaded barrel on my USP (SD variant) - that O-ring is tight and a nice upgrade. Any Canadian available attachments ?

What do you mean attachments? What do you want? Unless you get it cut for a dot your pretty much limited to a light...

And even then it’s a proprietary rail so it won’t be a matter of slapping any 1913 mounted light on it without a rail adapter.

GG&G makes a USP pic rail adapter. Works great, had one on my USP45 before I (stupidly) sold it before the freeze. Got mine from aztech armory.

There are a handful of different attachments for the barrel (comp, flash hider) - seeking what may be available in Canada otherwise may go back to Aztech and browse

I don’t understand why HK didn’t just making their frames with standard pic rails.

"Rails" on firearms didn't exist at the time it was developed. The USP (MK 23) was one of the first firearms that had an accessory rail. The industry settled on a common standard later. Just like Glock cross slots aren't true 1913 sized.
