Piston X-rings (Non-Boreup)
Part 6540K167 (Viton) - $9.06 for pack of 10
Part 90025K238 (Duro) - $12.72 for pack of 100
Note: Vitons CONFIRMED working. However, Duro results from one user has shown completely failure in compression for multiple guns. Until further notice/further testing from other members, please refrain from buying the Duro ones. Plus, the Viton ones are better Cheesy

Part 90025K244 (Buna) - $13.00 for pack of 100
Note: NOT CONFIRMED

Part 90025K361 (Buna) - $12.06 for pack of 100
Note: Might not fit some, as the diameter needed is in metric (MMC doesn't provide metric for O-rings).
Cylinder X-rings (Boreup)
Part 6540K166 (Viton) - $12.67 for pack of 25
Part 90025K362 (Buna) - $12.10 for pack of 100

GBB Fill Valve O-rings - courtesy of sdobbins
Part 9263K511 (Viton, small for KWA/TM M92/1911) - $6.08 for pack of 25
Part 9262K441 (Buna, small for KWA/TM M92/1911) - $12.40 for pack of 100
Part 9263K289 (Viton, large for KWA/TM Glock/Hicapa) - $3.33 for pack of 25
Part 9262K422 (Buna, large for KWA/TM Glock/Hicapa) - $4.39 for pack of 100
For making sure you don't leak gas when filling up magazines. To tell the size of your fill valve:
Large: OD = 7.0mm
Small: OD = 5.5mm
Note: NOT CONFIRMED. I will have to research sizes again for this one.
Angle of Engagement Piston Adjustment Nylon Spacers
Part 95606A180 (0.028"-0.034" thick) - $7.52 for pack of 100
Part 95630A445 (0.027"-0.035" thick) - $7.03 for pack of 10 (thanks grmash)
Note: CONFIRMED working.
The 2nd listing is for a bushing that covers the entire area of the piston head. The 1st one is for a bushing that just goes around the outer diameter of the piston. The 1st one is cheaper, but it might allow for possible spacer movement - the 2nd one is preferred.
Polyurethane/Sorbothane Pads
Part 8514K51 (1/8" thick, 40/50/70D) - $4.85 for 4" x 4" sheet
Part 8514K52 (3/16" thick, 40/50/70D) - $5.37 for 4" x 4" sheet
Part 8514K53 (1/4" thick, 40/50/70D) - $6.44 for 4" x 4" sheet
D refers to durometer, or how hard the material is. Harder durometers are suggested for stronger springs (over 400fps) and softer ones are suggested for weaker springs. Do note with thicker pads, you may need to short stroke and do AoE adjustments for the piston.
Note: CONFIRMED from other sources.

Part 2418T117 (Duro, -11, Medium-Soft, Milspec) - $9.97 for pack of 115

http://www.airsoftretreat.com/forums/index.php?topic=40038.msg436432#msg436432I have 2 options for the -11 O-ring since TF mentioned they should be soft, but the only ones that are med-soft are MilSpec ones - Std ones are hard/very hard.
Note: NOT CONFIRMED.
Grenade Bearings
Part 9528K12 - $3.15 for pack of 100
Apply to MB grenades (tested and proven) but should work on any grenade that uses bearings for the reset valve.
Note: CONFIRMED working.

Motor Connectors, Double Crimp
Part 69525K87 - $1.52 for pack of 10 (16-14AWG wiring), $6.76 for pack of 100
Part 69525K84 - $1.52 for pack of 10 (18-22AWG wiring)
**Part 69525K59 - $1.47 for pack of 10 (16-14AWG wiring), $5.71 for pack of 100**
Note: CONFIRMED working.
Note 2: The last part added, 69525K59, I found on a very old order history in my email - they are measured as 0.110" x 0.020", which SHOULD be the size of standard motor connectors you find in most guns. I do not remember ordering those (possibly since I used them all), but if anyone can order these to confirm, I'd be grateful.
Right-Angle Motor Connectors
Part 7769K31 - $1.56 for a pack of 10 (18-22AWG wiring), $6.76 for a pack of 100
Part 7769K33 - $1.56 for a pack of 10 (14-16AWG wiring), $6.76 for a pack of 100
Note: CONFIRMED via other sources.
Note 2: Both these connectors measure 0.187" x 0.020", which are larger than your standard connectors - MCC doesn't offer right-angel connectors in the 0.110" x 0.020" size. I suggest using the straight motor connectors listed in the group above, but if you really want to use these, make sure your gun/GB setup can accept the extra size.

1/16''-thick RDS/Scope Plexiglass Protectors
Part 8574K24 - $4.07 for 12'' x 12''
Part 8574K38 - $6.94 for 12'' x 24''
Part 8574K51 - $12.42 for 24'' x 24''
Note: CONFIRMED working.
0.78''-thick Lexan/Bulletproof Plexiglass
Part 84805K31 - $110.50 for 12'' x 12''
Note: Never bought, too expensive.
Note 2: Lexan is widely known to be bulletproof, but for most airsoft uses Plexiglass is enough. Lowe's and Home Depot both sell Plexiglass/Lexan as well for decent prices. I can say that Lexan is EXTREMELY strong (able to not crack under several hammer hits) and if you have the money, it's definitely worth it.
Wire Mesh (Perforated Steel) - 41% Viewing Area
Part 9255T251 - $39.73 for 36" x 40"
Same mesh that Bitter End uses in their mesh goggles - perforated steel (VERY strong), and NOT woven mesh. However I cannot endorse that these provide better protection than ANSI-approved lenses for googles; use at your own risk.
Note: Never attempted, though uscmCorps of Arnie's has used it on a "Heat" mask.
Hardware Store Items (Home Depot, Lowe's, etc.)
Mock Mock MOCK mock mock mock mock mock mock mock mock mock mock mock mock mock mock mock suppressors
1.5"/1.25" PVC/CPVC/Aluminum tubing for outer cover, 0.25" PVC/CPVC/Alum tubing for inner "outer" barrel.
Best to mold over stock flash hider - there are multiple threads about making mock mock mock mock mock mock mock mock mock mock mock mock mock mock mock mock mock mock suppressors. If you need help please post in this thread.
I find that 1" PVC works best, along with some tough CD's - the result is lightweight, yet tough. Use JBWeld to glue sections together.
Spacers (from 1/4'' to 1'1/2'')
Spring spacers can work in both springers and AEG's (not recommended). Mainly for use in spring guns/rifles. Look at your local store for "brass compression sleeves", like this one:
http://plumbing.hardwarestore.com/52-330-compression-sleeves-and-nuts/1-2-brass-compression-sleeve--653732.aspxNote: CONFIRMED working, both on DPMS A-15 and Hardballer in the far far past Cheesy.
Barrel Threading Nuts
If you need nuts for your own custom flash hider or mock mock mock mock mock mock mock mock mock mock suppressors, Katatonia has suggested 9/16" nuts or, if metric, 14mm. The actual measurement is 14mm, but this is the closest English measurement; if you have access to metric ones, that's better.
JG Bar-10 Stock Screws
Rear screw #10-32 x 1-1/4" (Round Head slotted)
Front screw #10-32 x 5/8" (Round Head slotted)
Note: One user has said that the gun will not cock anymore with these screws attached. Please someone else confirm this.
You should be able to source these from Home Depot or anyone else that sells screws - just ask! Thanks to CottonTheMoth for the info.
M4 Buffer Tube Screws
Quoted from PaperPlane (thanks):
I'm not sure if it is the same size for all other AEG's, but for my Echo 1 HK416, if you lost the bolt that connects/secures the buffer tube to the body, you can use part number (10-32) X 3in. I couldn't find any with phillips heads, but I just got the single slot head since I didn't really care.. There are 3 bolts per package, and 3 nuts. It's in a green small package, costs 98 cents, and it says "MACHINE" on the top. Can be found in the nail/screw/fasteners section at Home Depot.
