Aight, fair warning though, some of this stuff is currently out of stock and I don't know when they'll be restocked and it's been a while since I ordered some of these parts, but I'm pretty sure they're all sitting in my gun at the moment.

​

Also, if you need help installing anything or have any questions, feel free to hit me up.

​

Let's preface this with some general stuff that you should have on you:

A set of O-rings won't hurt to have, even if you only need the smallest ones

Superglue also doesn't hurt to have, I had to use some

​

Starting from the Magazine:

Extended mags are always nice to have

Nine Ball high flow valves

\^ For these, you're gonna want to replace the O-ring on the moving piston of these with smaller ones from that box, then glue it in place. I had an issue where the standard sized one would shift on me when I fired, which really hampered the amount of gas released then kept the valve from closing all the way, leading to the magazine leaking out after one anemic shot. Replacing the O-ring and gluing it in place fixes that

​

Going to the actual gun:

Poseidon ICE Breaker Piston Head

\^ Installation's a bit funky, you're gonna want to take the screw from your factory piston head and use that with this piston head without the factory cup looking thing that comes with it

DP Enhanced Rocket Valve

\^ This one's pretty simple, just a drop-in piece

Action 150% Enhanced Hammer Spring

\^ I Think this is what I ordered, it looks pretty similar and if memory serves you should install it with the tapered end down

A+ 6.01 Precision Inner Barrel & Rubber Set

\^ Really just a simple drop-in, don't lose your gun's hop-up bead!

RA-Tech Steel threaded outer barrel

\^ This one is kind of weird, and will need three O-rings to get working to its greatest potential. When I first dropped this part in, my gun was literally chewing up BBs and spitting plastic chunks out. To remedy this, use two more O-rings from that box and put them around the inner barrel, this fixed the problem for me. The last O-ring is a real steel part and goes into the groove on the outside of the barrel and is there mainly to improve accuracy. Plus, the barrel doesn't come with a thread protector so you'll want to pick one up separately, the barrel uses 16mm CW threading

​

Bonuses; stuff that you could pick up and use, but I haven't for whatever reason:

Sights: I use the standard sights because pretty early on I poked out the little white plastic dots and replaced them with glow paint, as well as custom mounting a fiber optic holder for the front sight (PM me and I'll send you the STL) but you could give the tactical sights a try

USP Tactical Front Sight

USP Tactical Adjustable Rear Sights

USP Comp-Tac Front Sight

USP Comp-Tac Rear Sights

\^ The compact tactical sights look like they'll fit on the standard slide, but I don't know. Front sights are held in by friction and should be glued down, Read sights are held in by a hex screw that goes in through the BBU

​

Recoil Springs; I bought these, then realized that since I live in Massachusetts, it's too cold most of the year to actually use them to their greatest potential

Enhanced Recoil Springs

\^ Only the big one on the outside actually does anything, so you only need to worry about installing that one

These are for real steel guns, and feel really solid, I have no doubt they'll work on GBBRs, but I have an aeg, so I can't base that on personal experience.

I have a Sightmark Ultra Shot QD and it's fantastic. Big glass, multiple reticle, really solid, bright(works in direct sunlight), qd works. I'm very happy with it.

They also make a non-digital non-qd version that's even cheaper, but I really like the QD.

Good luck

Joule creep. Seems pretty common with GBBRs.

I don’t have a link - I had it sitting in a bin of small parts. No telling where i got it from originally. It looks more or less like this one: https://www.amazon.com/Winco-A81760-DIN6319C-Spherical-Washer/dp/B00S6BZH6C/ref=lp_16410941_1_5?s=industrial&ie=UTF8&qid=1572709074&sr=1-5

002 Silicone O-Ring, 70A... https://www.amazon.com/dp/B000FMYEO6?ref=ppx_pop_mob_ap_share

I use these for my GBB M4 Mags
