Sale Posted May 30, 2008 Report Share Posted May 30, 2008 If your outer barrel wobbles and the RIS is half falling off, it means that the barrel nut is not fully tightened. -Sale Quote Link to post Share on other sites

But the results are nice for a 100 dolla upgrade. Quote Link to post Share on other sites
vtb Posted May 30, 2008 Report Share Posted May 30, 2008 Got mine yesterday at last. Recoil is on par with Escort HK416 GBB on 150PSI. Quote Link to post Share on other sites
Romulus Posted May 30, 2008 Report Share Posted May 30, 2008 Holy ###### that's a huge jump in FPS!!! I had no idea it would be so much better just with the addition of the inner barrel! It is pretty amazing. Tightbore barrels do way more for GBB than AEGs. I'm really happy to see that my hopes for a good power boost came through. Actually the whole deal sounds pretty slick. Going from CQB power to full woodland power could be as simple as switching gases. It would be fun to see some actual 100, 150, 200 foot grouping from the gun if you ever have a spare moment.

Chris North Posted May 30, 2008 Report Share Posted May 30, 2008 WA M4 with full lenght barrel not at RedWolf: http://www.redwolfairsoft.com/redwolf/airs...il?prodID=24688 Bit more expensive though. Probably be better to just get the CQB and a G&P barrel, right? Quote Link to post Share on other sites
Titleist Posted May 30, 2008 Report Share Posted May 30, 2008 MY GOD, that big of a jump with a tightbore?! Hot damn. I'll build one of these guns soon once the body and barrel/carrier/metal bits get resolved. Quote Link to post Share on other sites
uscmCorps Posted May 31, 2008 Report Share Posted May 31, 2008 Before with stock barrel: Duster 260ish FPS GG/Propane 360ish FPS After with PDI barrel: Duster 310 - 320fps GG/Propane 460-480fps. Just to clarify, these are velocities measured with 0.25 gram BBs right? Did some quick testing last night, and got a very consistent 350 fps using 0.25g Excel Non-Bio BBs. It'll be interesting to see how the velocity differences are between the various PDI tightbore barrels compare. If the step up in velocity is consistent from barrel length to barrel length, then it might be a possible way for people to pre-tune their guns to shoot at a certain FPS. Placing an order for the 368mm tightbore and 9 spare mags tonight. :X Gonna install the G&P M4 front end tonight too. Quote Link to post Share on other sites

uscmCorps Posted May 31, 2008 Report Share Posted May 31, 2008 Sorry these are with .20g Wow... then my 350 fps with 0.25gram BBs is pretty dang good! Quote Link to post Share on other sites
poison123 Posted May 31, 2008 Report Share Posted May 31, 2008 Wow... then my 350 fps with 0.25gram BBs is pretty dang good! I've seen a fair amount of variance with the Ga. weather vs the Ca. weather. Though mine might be higher.....once I get the stupid barrel to stop wobbling. Quote Link to post Share on other sites
Lupus78 Posted May 31, 2008 Report Share Posted May 31, 2008 Wow. Just what I hoped for. That kind of performance jump would be just perfect. :-) With the PDI barrel and Airsoft Surgeon's light bolt this could actually be a great gun even with duster gas. Quote Link to post Share on other sites
vtb Posted May 31, 2008 Report Share Posted May 31, 2008 Well. mine got issues... =) 1. Guarder 0.28 BB's stuck in the hop... It'a only a guarder problem? 2. the same part just broked well... it's bad part. Good news 1. SP handguards fits fine.... 2. Changed base recoil spring on SP recoil spring... will chrono the changes but 0.28 BBs fly visibly faster and range is greater. Quote Link to post Share on other sites
hokeyplyr48 Posted May 31, 2008 Report Share Posted May 31, 2008 vtb, which part exactly broke? what is it in the picture? and after how many rounds did it break? Quote Link to post Share on other sites
poison123 Posted May 31, 2008 Report Share Posted May 31, 2008 vtb, which part exactly broke? what is it in the picture? and after how many rounds did it break? Thats the hopup housing that broke. vtb can you link me to that spring and handguard? Quote Link to post Share on other sites
vtb Posted May 31, 2008 Report Share Posted May 31, 2008 Handguard is from XM at the bottom (sun project) Recoil spring is from it either. Tested it more - with such hard spring BB's jam. 1 good shot for 1 good jam -) But stiffer recoil spring (in the stock buffer tube) seems to make FPS higher - it's question of balance - because with spring from SP BB's a cracked apart in the entrance of hop-up (the hit is very strong) Quote Link to post Share on other sites
chillindrdude Posted June 3, 2008 Report Share Posted June 3, 2008 anyone with new info about possible metal reinforced internal parts in the pipeline? im about to buy this but want to make sure there are parts coming in the future Quote Link to post Share on other sites
AnakChan Posted June 3, 2008 Report Share Posted June 3, 2008 Wupjak/Poison123/VTB, I'm naturally interested in WA M4 (esp when the actual WA shop is like 2-3 km from my home!), and it seems more decent after market parts are coming up with it but with the weak hammer and hopup chamber, I'm wondering if you guys have any concerns about our respective purchases? These problems seem major but it appears you guys are still skirmishing with your M4's. Would you say the product is ready for the market now or would you recommend to wait for version 2 to a prospective buyer? Note that if I do go for it, I'll be using this in Hong Kong (green gas) as well as Japan (HFC134a). Quote Link to post Share on other sites
Magsz Posted June 3, 2008 Report Share Posted June 3, 2008 It seems as though all this gun REALLY needs right now is a reinforced hopup collar and some of the gubbins involved in the bolt catch. Is that a correct assumption? If so, im sure someone will be releasing those parts in short order. Quote Link to post Share on other sites

Is that a correct assumption? If so, im sure someone will be releasing those parts in short order. I'd say it's a correct statement Yes. 2 parts. 1. hopup collar - brokes but (in mine case) it didn't affect range and groupings 2. plastic tiny bumber on bolt catch - yesm it's need to be changed. but it can be done later...

Inq Eisenhorn Posted June 4, 2008 Report Share Posted June 4, 2008 I don't know if this is "news".......but I can confirm that the mags for these in the UK are coming in at around £77, so thats about $160. I think anyone buying this rifle in the UK will probably be shipping these mags in from HK. Quote Link to post Share on other sites
snowman Posted June 4, 2008 Report Share Posted June 4, 2008 Aren't they around $100 in Hong Kong? Add on 20% and you've got £60 and then you've got postage, too, which is probably going to be £20 even if you only buy one (and buying 4 or 5 is going to be expensive!) Scarily, £77 doesn't sound too bad! Cheers. Quote Link to post Share on other sites
Karlos Posted June 4, 2008 Report Share Posted June 4, 2008 Maybe i'm a little premature with this question but does anyone know what the inner barrel length of the recently released full length WA M4A1 is? Quote Link to post Share on other sites
Wupjak Posted June 4, 2008 Author Report Share Posted June 4, 2008 (edited) I think the issue isn't so much the BB brand as much as it is the weight and the resultant amount of hop up required to get the bb to stabilize in flight. The hop up arm is shoved further into the path of the bb and the projectile is unable to get past the hop up rubber/arm, resulting in a jam. The next stripped round from the magazine then collides with the jammed round, takes the path of least resistance and busts off the upper hop up chamber lip. I also busted my hop up as you did with .28g's. Associated with this is the fact that the hop rubber gets more and more slippery with more shots through the gun, so you have to dial in more hop up as the hop up rubber gets fouled/the magazine cools. Well. mine got issues... =) 1. Guarder 0.28 BB's stuck in the hop... It'a only a guarder problem? 2. the same part just broked (pic) well... it's bad part. Good news 1. SP handguards fits fine.... 2. Changed base recoil spring on SP recoil spring... will chrono the changes but 0.28 BBs fly visibly faster and range is greater. Edited June 4, 2008 by Wupjak Quote Link to post Share on other sites
vtb Posted June 4, 2008 Report Share Posted June 4, 2008 Well, I've tried 0.28 Guarder from another package - they worked fine... so i assume that's the question of BB's Discovered strange issue - hop in two max positions (max "+" and max "-") works equally - BB's just drop. But in the middle of regulation range - it's possible to make flat 50-60meters trajectory with little climb at the end. Quote Link to post Share on other sites
Magsz Posted June 4, 2008 Report Share Posted June 4, 2008 Wup, why not just use regular propane with no silicone added to avoid the issue of fouling the hopup. I mean, realistically speaking you dont NEED silicone in there if you maintain the rifle every now and then. Quote Link to post Share on other sites
