cobra2 Posted September 18, 2008 Report Share Posted September 18, 2008 I know it... I'am not stupid ;-) The outer barrel is 10.5 inch long and the PDI inner barrel is 8.26 inch long, So I want to know if it's not too short, or if I need to buy the PDI 12.8 inch inner and recut it ?

To get the length of the cqb outer barrel you'd need a 250mm-ish inner barrel. How did i figure it out? Measured the distance of no barrel from the tip of the stock one to the opening of the outer barrel. You should really be able to answer your own question. Quote Link to post Share on other sites
kuyadlo Posted September 18, 2008 Report Share Posted September 18, 2008 (edited) Finally finished   G&P Sr-16 metal body G&P TD Pistol Grip G&P BB hammer Set G&P 120% Hammer Spring G&P Steel Sear G&P M4 Outer Barrel G&P Recoil Spring and Buffer RA Bolt Catch RA Hop Up RA TB 363 KA MRF-CX Rail KA Battle Sights Replica Aimpoint  Installation of Metal Body was a breeze. only problem i had was the upper receiver would wobble. fixed it by shimming, now it is rock solid.  chronoed at 500FPS +/- 3. shoots very straight.  played around with the trigger sear and hammer to reduce trigger pull..trigger pull now is smoother and lighter.

Â The problem is I'have not receive my WAM4 CQB-R yet, so I can't measuring anything And I want to order all the upgrade parts Does anybody can give the lenght of the stock CQB-R inner barrel ? I think the PDI CQB-R is too short, but I need a confirmation. Quote Link to post Share on other sites
junior Posted September 18, 2008 Report Share Posted September 18, 2008 Very nice kuyadlo. Â I think a regular front sight tower would go better with the MRF-CX then the flip up sight, but it still came out sweet. Quote Link to post Share on other sites
shinhk Posted September 18, 2008 Report Share Posted September 18, 2008 Finally finished <pics> I see you went the G&P route. Nice expensive list (cept for the "replica" compm4 he he) but i agree with junior as either the front iron post or a flip front sight for that gap would have been a better choice. Kind of seems like it's missing something...with an extra part. Or you could have bought a RS troy MRF-R for probably another $100 I'm just teasing yah but nice to see you did the upgrades on your own without any problems  Does anybody can give the lenght of the stock CQB-R inner barrel ? 210mm is stock but it doesn't go out to the barrel.

kuyadlo Posted September 18, 2008 Report Share Posted September 18, 2008 i was going to go for the flip up sight but couldn't find one..so i just placed a gas block there..kinda growing on me right now. i've tried the RA hammer and it wasnt' working for me. so went for the g&p and it works alot better. this gun is expensive...i ran out of funds..=/..so on goes the replica..=P Quote Link to post Share on other sites

Lupus78 Posted September 20, 2008 Report Share Posted September 20, 2008 OMG. That's seriously sweeeeeet! Even aluminum nozzle! Cool... Â I wonder how well that kind of a heavy steel bolt would operate in Finnish (cold!) climate. Aluminum bolt might be the best option here. Quote Link to post Share on other sites
IBICO Posted September 20, 2008 Report Share Posted September 20, 2008 The prototype bolt with feeding nozzle weigh 315g. They have plans to get 50g shaved off when final. Â Now I don`t really remember how much the original weigh for a complete bolt with bolt carrier Quote Link to post Share on other sites
Kalmar Posted September 21, 2008 Report Share Posted September 21, 2008 I'm still quite new to this weapons and airsoft in general... so I need some more information about the trigger assembly before I rip it out not knowing how to put it back in. If anyone could post a descriptive guide (pictures please?) I and I'm sure many others would greatly appreciate it.  Myself being primarily interested in removing and installing:  Bolt Stop Hammer/Bearings Hammer Spring Sear  *If the above are identical to real steel trigger packs could some one point me in the direction to a guide of this sort?  Equally important to me is knowing what do to and how to install:  One piece barrel (IE: how to remove standard two piece - barrel wrench necessary?) RA-Tech Hop Up housing (or any other you may know how.) + Precision inner barrel  Some of these are most likely self evident after removing the stock pieces however I would much rather know what I'm getting into before I risk my time and this very expensive gun, so I ask those of you that have done so before and know what you are doing to please lend a helping hand.

fmxona500 Posted September 22, 2008 Report Share Posted September 22, 2008 When I had the plastic body on mine, the rear pin was too tight. Had to use a punch to get the pin out. I ended up drilling it out with a drill bit and it was smooth after that. Â After I installed the G&P metal body I found that it wasn't drilled straight. Had to take the dremel to the upper reciever to get the pin all the way through. No big deal really. Now it does have alittle play/wobble. To be honest with you too, it's just like a real M4 now (since US Army recievers aren't matched.) Quote Link to post Share on other sites
cobra2 Posted September 22, 2008 Report Share Posted September 22, 2008 (edited) Excuse my bad english... I can't find the good word, I want to talk about the part that holding the bolt stop and firing pin. I Hope 2Roy or Ra-Tech will produce one quality CNC part for replace the stock pot metal one. This stock part is horrible and waste the receiver. Ibico, do you have some information about that ?

kullwarrior Posted September 23, 2008 Report Share Posted September 23, 2008 which one are you talking about? RA-Tech's or PDI? you can basically estimated the fps out, I don't think anyone has right now. RA-Tech's 250mm is about 450fps, 368mm is about 528 fps so basically estimated about 630fps... don't take me for quote but just using those two's info you can judge about the fps roughly Quote Link to post Share on other sites
IBICO Posted September 23, 2008 Report Share Posted September 23, 2008 I am getting a WA M4 that need repairs soon.. + 509 pdi 6.01 barrel. I could test it then. Would post it at gasguns.info Quote Link to post Share on other sites
