I am making myself a replica Barrett M107 Bolt action Airsoft Rifle. As of right now I'm in the designing stage. Before I mill or lathe anything out, however, I need the internals. Problem: I don't know what the best internals are, and I really want the best I can get for my budget.

I have been told to look for Laylax, and so far I believe I will be using the Laylax PSS10 190SP Spring for VSR10(this is not for field play, solely for play with friends/recreational target shooting) I want the 600FPS, and I know it will not be easy to pull.

For the barrel I was thinking of using the Prometheus EG Precision Inner Barrel for TM M14 (500mm) because I have heard prometheus is good and I need a 500mm barrel.

I am planning on ordering parts from Airsoft GI(http://www.airsoftgi.com/) so this brings my total to $91. I still need hop-up and a piston(I was planning on making the cylinder myself, as it seems quite simple and I have access to a CNC lathe). I have 12 inches(I could probably push it to 15 inches) in which to fit the spring, piston, cylinder, and hop-up.

My budget is $200. This is a rough budget, I could probably got to around $225. So with what I already have around $109 left for the hop-up and piston. I need a full hop-up, and I do not plan on buying a boneyard gun. The reason I am asking for help is I do not know much about what is best for the internals of an airsoft rifle, and I am looking for good accuracy, range, and power and do not wish to get a bad part and have to buy another.

I will update this thread with reports and pictures of my progress when I get into the building stages.

Thank you!:)

P.S. If this is the wrong place to post this I apologize, it seemed like the best out of the options I had.

Either way I think he'll pass his budget don't you agree?

He needs a receiver from a donor gun plus the rest of the upgrade parts.
If he choose the semi auto V2/3 option it'll be cheaper as he could buy a used GB.
IMHO it's easier to track a cheap V2 or V3 GB than a cheap let's say BAR10.

so a happy day today! got some mail that pleased me quite a bit, my tax return, and a bank statement. I now know that i have quite a bit more cash than i thought. my original budget was based off what i have in my wallet, as i thought i had nothing in the bank. yea... i was wrong about that one.>:D

any way im back for some help... i was looking to use mostly VSR10 internals... but all the barrels are waaaay to short, and ive read that the PDI hop up i was gonna use is prone to failure. im still wanting to use either a 190 or 170 spring. i also plan to get an IR-hop from HS5 armory.

so my dilemma is barrel, hop up chamber, bucking, cylinder, and piston, as all these were sorta blown out of the water when i read about the hop up failing. any suggestions? any place that i can start looking? my budget is around $250-$300. and the barrel needs to be a minimum of 500mm(id prefer a Prometheus 6.03 TBB)

You could get a high quality AEG barrel of the length you desire and then either:
A) Cut the VSR-10 ring and flat spots so that it works with the stock chamber
B) Get the PDI chamber for the VSR-10 since it accepts AEG barrels

I'm just not a fan of the PDI chamber but I think you should try it with an M4 chamber and PRothemus barrel, why? Because the M4 chamber seems very easy to upgrade to an ER-hop, and it has a simple design with a long arm so a flat nub can be used too. Of course Cheeseman is more qualified than me to say this considering he does these as a job :p but I think you should try it. I would.
