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

hacksaw, bandsaw, lathe, pipe cutter... take your pick:)
I think more along the lines of a lathe, because the barrel doesn't need to be cut all the way through at that spot, just a deep ring that the end of the bucking can go into. Really, you could just cut that piece off of the bucking and be fine, just make sure the end is sealed up tight.

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.
