I find that its about half and half these days. HK bags (or the plain bags with HK sticker), or plain bags. I do think its pretty funny to get something like I did recently: one MR takedown pin detent. That piece of metal is so tiny that the 5x10" HK bag outweighed the part by a longshot.
The JF mag well kit has always come in a clear (but thick) plastic bag like what you received. The LEM and Match Trigger Kits are the same way. Having said that, all the springs, HK45C extended mag releases, Match sear springs that I bought 2 yrs ago from the HKWebshop, each came in their own HK branded little baggies.
Thanks. It makes more sense now. I was trying to show others that not everything from HK comes in HK branded bags.
I received a presumably new G36 K/C gas piston sealed in the HK retail bag once from their web shop, where the piston was clearly used with fouling on it. I still have it, kept it in the bag because I thought it was funny, though unprofessional of them to bag an item clearly used. Maybe they decided to test that one piston before selling it? Haha
Imagine buying a new car direct from the dealership, then find the tire tread is at 75% or less.
