How does this build look for my KWA SR-10? Please post any suggestions or recommendations for me as I am relatively new to KWA's products.

-Lonex v2 high torque motor
-Lonex m170 polycarb piston
-Lonex silent piston head
-Lonex v2 cylinder head
-Lonex steel cylinder
-Systema m150 spring
-Lonex 70 degree hopup bucking (Also looking at firefly hard bucking)
-Aeg W hopup (should I get a r-hop instead?)
-Guarder 6.02mm interchange TBB 455mm
-DEANS
-GATE PicoAB Mosfet w/ Active Braking (I'm still not sure of this, please give other suggestions!)

-Shimming set, 11.1 lipo battery, I am also using .32g BB's

I am open to any suggestions. I am going for mostly range and accuracy, but I also wanted a higher fps. Also I was wondering what type of mosfet would work to make my gun semi-auto only? Or if there was a selector plate I could use (whichever one is cheaper =D). I heard the stock sr-10's internals can hold a m150 spring, but should I upgrade anything else? Sorry for the excess of Lonex parts, but one of my friends said they would fit, so I just wanted to keep it to one brand. Please give any suggestions/comments below. Thank you!!

Will I have to upgrade the bearings for the stock kwa with all the new upgrades, or should I buy some just in case?

If you do a good job of shimming the bearings should be OK though it wouldn't hurt to have a new set on hand in the event of a failure.  In fact, if it were my gun I would probably put new KWA bearings in so they are fresh and unworn.

Regarding the build overall, if you are changing the piston head the KWA nozzle may not be a good fit and compression could suffer.  Be prepared to change the nozzle or go back to the OEM cylinder head.  Personally, I only use KWA cylinder heads in KWAs. Why?  Because they give great compression and while they can break on occasion, they are not expencive and easy to source typically.  Now, this would mean that you would need to use either the KWA piston head or a similar flat head rather that the conical Lonex Silent PH.

We never established what FPS (with .2's as a reference) that you wanted to achieve.  You may find that an M150 is overkill.  I've shot with Guarder SP130's in the 500 range with my KM4A1.  How much higher are you planning on going?

Hope this helps.

I just checked my piston head and it seems fine so i'll just use that if it'll give me better compression. As for the fps, I will be switching between both the m150 (I usually play with my a couple of my friend's at their airsoft fields it is 11 acres, so a better spring would mostly help me give a better impact and range on them) and a m120-130 spring for when im playing at my local airsoft field where the fps limit is 500 for semi-auto only guns.

Great, keep us posted.  I like Lonex parts and if they mate well with the KWA nozzle that would be a good thing to know.  Looking forward to the updates.  Keep in mind that while the 2GX gearbox is very strong, adding a metal cylinder head will increase the stress to the front of the gearbox.  It may not be an issue but it's something to consider.  In fact, I believe Vanavery radiuses the front and rear point of the gearbox where the cylinder is held.  This helps distribute that force of the piston and could be useful in a DMR build.  And as mentioned in other threads sorbo pads are your friend.  This will most likely require an  AOE adjustment due the the change in dimension of the cylinder head and piston head and especially if you add a sorbo pad.

Have fun with the build!

I was considering sorbo pads since I recently saw a thread on those, but as for radiating the gearbox I will definitely consider doing that and of course an AOE if needed.

Also do you have any recommendations as to what sorbo pad I should use?

Parts:
-Lonex v2 high torque motor
Yes.
Their are possible Quality Control Issues with Lonex Motors right now, so keep that in mind.
My favorite all time motor is the AMP 5000TL.
If you are lookinf for cost effective, high quality motors, the ZCI and HC motor form Clandestine airsoft are worth taking a look at.
I recently purchased a couple of the ZCI motors and am very impressed with what I have seen so far.
The Neo Magnets are among the strongest out there with these motors.

-Lonex m170 polycarb piston.
No.
This Piston is notorious for not meshing well with KWA Sector Gear Teeth.
It may or may not, depending on the generation.
Try the Lonex Blue or something else.

-Lonex silent piston head
No.
Bumper Style Piston Heads will not add performance nor make your gun more quiet.
Your stock Piston Head is actually very good.
If you want a ported Piston Head. G$G Aluminum Ported Piston Heads are my go to Piston Head for DMR's right now.
The Lonex Aluminum Ported is also awesome, too.

-Lonex v2 cylinder head
No.
The stock KWA Cylinder Head is excellent and the Cylinder Nozzle it contains will work best for preventing compatibility issues

-Lonex steel cylinder
Sure.
If you change out the Cylinder, go for a Full / Type-0 Cylinder.
Otherwise, purchasing a ported Cylinder for a DMR Build when your stock KWA Cylinder already is ported may just be a lateral move, or one that just yields less performance.

-Systema m150 spring
I would advise lower fps.
An m130 or m135 spring should keep you under 500fps.
Your gun can handle the m150 with no problems, but I highly suggest not going so high with the fps unless you are an expert at shimming and Hop-up related information.

-Lonex 70 degree hopup bucking.
Yes.
Lonex 70 Degree for the win!
You may need some 100% silicone oil to install it into the KWA Hop-up Unit.
Hobby Shops sell it.
It is known as Shock oil.
Get 30wt.

-Aeg W Hop-up (should I get a r-hop instead?)
Not sure what a W hop-up is.
Only R-hop if you do the install.
Otherwise, focus on the Basics of Drop-in Bucking installs and do those yourself.

-Guarder 6.02mm interchange TBB 455mm
Never used a Guarder Barrel.
The KM Barrel sold at the KWA Pro Shop gets great reviews and I am a big fan of MadBull Inner barrels.Your stock KWA 425mm is excellent by the way.
I do believe a 455mm would be more optimal for performance.

-DEANS
Yes.

-GATE PicoAB Mosfet w/ Active Braking (I'm still not sure of this, please give other suggestions!)
Just purchased a couple of Gate Mosfets.
Have not yet installed them but will let you know how they do.

Advice:
Keep it simple.
Be patient.
Work within your skill level.
A full Cylinder, Quality Heavy ammo, and perfect air seal is a money combination.

Keep us updated.

I used a old cell phone case, was made of some soft strong silicone (1/16 or 1/8  inch thick) got my AOE where I needed it.. Cut a circle and glued it on.  Went into it after 20k rounds, looks like day one. Also had a good sound to it. Dont waste money on fancy online stuff for rubber piston pads. Visit hardware store. Save your money for cool stuff, fets, barells, motors, ect. Have used a Gate 3/4 mosfet in a CA build for the most part of this past year, working great.

Thanks for clarifying/suggesting parts, Vanevery I took every one of your suggestions besides the m170 polycarb piston since my friend allowed me to see if his fit into my gun, which it did and shot very well (he bought it 2-3 weeks ago so the generation i'm guessing will still be the same). I've already bought a sorbo pad (70d), but for future reference can you obtain a similar product from hardware stores?

Sorry for bumbing this thread, but I just thought I should let you guys know that all of the parts I bought worked. Lonex is an excellent brand to use with kwa, although the guarder tbb was a tight fit with the lonex 70 degree, but it got in there with enough lubrication. I would definitely recommend buying a 70d sorbo pad and shimming your gears for anyone else whos looking to upgrade their sr10. Thanks guys for all the help! Saved me a couple $$ with the piston head suggestion. I am using an m140 spring btw.

I went to an airsoft field and had the gun chronoed and it was at 500-505fps (with .2s). I range tested the gun (around 6000 bbs used in it so far) and with .36g bbs it's consistent within the 260-280ft mark, beyond that (300ft) I seem to hit every other shot (I bought a range finder on amazon, so the distance should be accurate). I would highly recommend this build to anyone who's looking to upgrade their sr10 into a dmr! Thanks guys.

Guarder 6.02mm 455mm tbb and lonex 70 degree bucking. I did compare the tbb with the stock kwa barrel and the guarder performs better.

What is the comparison like and how large a target are you using?  Thank you in advance!

I just printed out some targets on printer paper, so the size of your standard printer paper I guess. With the guarder I hit 9/10 shots at 250ft whereas stock I did 6/10 (I have a gun holder that's used to zero in sights, so the placement of the gun between the 2 barrels is almost exact). It wasnt windy out between the two comparisons, so wind shouldn't have been in issue.

They are some very good results.  Nice job and thank you for posting.
