Hello All,
I just received my Air Venturi Avenger 25 Bullpup 2. I'm planning a new thread about first impressions, unboxing, etc. but I first had a quick thought/question.
I'm about as new to this as it gets. My young days I plinked the 22 a bit but this is an exciting new thing for me.
My question is regarding the small bag of o-rings and various small parts included in the box. The few page manual covered their legal end and the absolute basics to fire a shot but zero indication or even point in the right direction when or why or how I may need these parts and then how to use them?
I have the exact issue with my pump. I have 2 I got open box but seem ok. Spritech and Vevor both compact $200 range ones. Both with this bag of mysterious parts.

I haven't yet pulled the trigger as excited as I am. I got horribly sick, fever, etc so might be a few days. Meantime, I'm overthinking everything 😆
Thank you to everyone. I'm just hoping to know where to go if/when it becomes necessary. Much appreciated
 
You'll know where they go when (not if) you'll need them. Companies usually send extras of the most likely to "blow". Search for the Avenger exploded diagram & see if it gives o-ring sizes. If you don't have a caliper for measuring, GET ONE. They're essential & indispensable tools when it comes to our guns. Not familiar with your gun but you probably were sent extra magazine o-rings (if that type of mag) & barrel and/or breech rings. PICTURES are always helpful!

Thanks... I did look at the exploded view will parts list/#'s. I didn't see anything with specs for each part.
I'll put together a few pics as i get into it deeper. I'm an engineer, not worried about getting my hands dirty but for the same reason I love to have every little tidbit of data/info before turning any screws. It's compulsive I guess 😆.
Thanks for the advice. I'll grab the tools I'll need now so no surprises down the road. From my quick peek it seems the info is all out there just need to pull it together I guess.
Thanks again

You're welcome! The spare parts for the compressors are USUALLY extra o-rings for the moisture filter, bonded washers (dowty seals), maybe burst discs, small white delrin washers, etc. You said "pump" but I assumed you meant compressors (@ $200). Good luck on your journey.

Yes, compressor. Just my lazy terminology. 😆.
Your right from what I see. Several burst disks along with filter o-rings, etc.
Honestly, it's a fun learning experience. I'll have to see if there's any reliability data (Life expectancy) for the main items. I'm going to try to document this best I can to have it in one place.
Thx again.
 
Oddly enough most of my engineering experience was working with high vacuum pumps (Semi conductor manufacturing mostly but also vacuum furnace, MRI, space simulation, even food packaging). Hopefully some of this I can flip into reverse. 😆
Just flip it and add a couple orders of magnitude to the forces😁 I haven't a clue and this is a guess for fun. I bet you have at least a breech oring and a shroud cap oring in those parts.

Since you're an engineer, you need to get an fx impact some day and appreciate the insanity of it.

Congrats on the new arrival, sorry you're under the weather but that'll pass. Have a few PCPs and labelled some plastic jars to keep all those spare parts together for each. Any parts removed from gun, like moderator thread protector, and extra parts, like single-shot trays, go in gun-specific jar, too. Just grabbing appropriate jar, when working on an airgun, is easiest for me. WM
