Bbbbuhh !! But its pretty

Just looking at your edit, i have already got hold of rainer arms regarding the Avenache http://www.rainierarms.com/rainier-arms-avalanche-charging-handle-black-5-56-knurled Looks real cool and not that bad price wise, should be roughly £13 import duty. Is there a point where customs start wondering what the hell you are buying haha First a grip, now a charging handle.

Looking into getting a real one, got some quotes out there to request a courier other than USPS as anything via royal mail into customs takes too long. The stark grip passed customs within a day while the DG took 9 days im sure.

Cool will get some swabs on the ready ! Haha, i pulled it back and all of a sudden the handle let go..Ooops lol Well i have been looking at the Rainer arms PTS as i just love the look of it, trouble is it looks like PTS dont make them anymore so i can only get the KWA variant. Any ideads what the difference would be between a KWA and a WE handle ?

Ok so after a hour of free time today i have worked out the issue. It seems that when manually loading a bb it sits snug in the hop ready for the air to kick its ass. But when allowing the bolt to cycle it pushes the bb no further into the hop but at enough speed to allow it to slip right past the hopup. Upon closer inspection, lube has been layering the hopup and barrel, hence why the bb slips past. If i add a ton of hop, and only then will it stop the bb from falling out but then looses 60 ish fps. This is also backed up by the fact that when pre loading the bb, i get a single shot as expected followed by one falling out which is simply the next in the cyle passing the hopup. No double feed, just too much lube. "never though id say that " On a down note, can anyone notice any issues with the picture below ? Looks like a new charging hangle is making its way to me sooner than expected

aha yeah lol, i think it was there it just wasnt clear. Since fixing the air leak its clear there is a other issue. It did fire a bit more normally in the past but never have i had 310 fps so i suppose i know im going the right way Lets hope it is

This was happening before the change it just wasnt clear as the FPS was wonky as hell.

Troble is this never used to happen. I have already got a convo going on, on the FAQ so hopefully this will shed some light. It doesnt always double feed with the same issue though.

R-hop installed and a few inches of ptfe tape later and all good. Barrel sealed nice and tight. But issue 2000, when firning with bbs fed by mag it causes the bb to dribble out the end of the barrel. If i preload a BB and fire with the mag in, the first fires out and second dribbles out. But if i take a single BB and feed it into the hop and cock it, it fires around 310 consistently "for each time i load one in. Any ideas ? EDIT I have also tried different mags and types with the same issue.

Im cradling it like the baby jebus, got another on order for the scar little more as its the 500mm.

Some new toys came today Absolutely beautifull finish, as you can tell !! Little longer than the origional but hey, looks its pretty. Side note, installed speed trigger in polarstar, MK17. Very nice and only a little bump and grind to get it working

You sure dude, i was half thinking buying a load in and selling them off as and when. PM me how much you want dude, may go for it so i can rule out the air leakingz.

Cheers dude, new realm of adventure Dont suppose you know of anyone doing the DG buckings in the UK ? I dont mind buying them off tony but its a long wait and expensive delivery order for some bucking. Need some to tie me over till i R-hop something, i have cracked the first bucking and nicked the second so pretty sure air is getting out. I did however find the leak, besides the bucking.. seems to be the slot for the bucking on the barrel seems to be letting it all out. Will teflon tape it for the moment.

Done the trigger job on ther DG, nothing better than drilling a £300+ kit part. Worked out pretty well, brought its own issues once installed though. Two things, one. In safe the shears are still able to push the valve back, hence premature evacuation of air. Two. The small tappet on the semi auto shear catches the DG shell due to its longer travel, easy enough fixable though.

Also, the 500mm seems alright. Like I said, high air consumption as I have to run at around 130psi, but as it's damn near impossible to get a straight answer out of the FB group I'm not sure if that's bad or not. I may cut a coil or two to reduce recoil and up the fps (so I can drop the pressure to bring it back to 1.17J), but I dunno. Yep well i had to do this to my mk17, got a aluminium madbull barrel tighbore 6.03. I r-hop'd that and also added a small bit of teflon mainly due to the WE freak of a hopup unit lol I was considering tefloning the DG up as something tells me that will help, i will do r-hop but only on new barrel. Well i did the same thing, tight and small amounts of locktight until break in is done then stick that shite together like crazy. Im already having to locktight external attachments and rail screws as it a shaker I did indeed check for any leaks and there was none to report, everything seems to function well, my gut feeling is hop/barrel. Hmm will see what to do with that, the mk17 is built as a DMR so R-hop with widebore sounds pretty sexy, im sure some retailer is going to have a little laugh when i order in almost 200 big ones for barrels alone haha. Doing DG trigger job tomorrow, sick of sloppy trigger. Also got plans for Mk17 but most likely just fill in the case to force the trigger to rest on the switch as the trigger is too small to drill and tap. Not yet due, only had it today so early days. Either way i will most likely get a orga for that as well Pretty much doing all the stupid things like max fps, and rof . Funny as hell listening to a fart sounding blare from it going at 60+ a second. Got ages untill my next skirmish due to work and Christmas, so lots of time to mess about and tweak.

Well what i am thinking is that evena slight bend in the barrel is causing the high pressure to flow out of this area. The more pressure the more that passes the bucking. I had a very similar issue with my MK17 a while back and that was a bucking leak hop to barrel that only showed its face when allot of air is introduced. How do you get on the the 500mm ? I was looking at that for the mk17 since getting the jack, "which is awsome btw". I gotta get something to drop the fps on the jack, at 60psi i am getting 350fps with normal hop on. Want to drop it so i can use heavier bbs with orga. Yep, really the only parts i have locktighted is the collar andthe carrier inner/outer screw. All else has been up tight which no apparent issues.

Haha yeah, i didnt hear too great things with the mancraft gear. Mainly its assembly and mechanics but no FCU is why the daytona was so great. I got a 800mha 7.4v for the jack so when i ever do use it, battery power shouldnt be a issue . With my low fps issue i have got a feeling that its to do with my barrel. When i first dis-assembled the hopup i may have pulled the barrel before unscrewing the hop nut! Intially when i took it all appart i found the hop lug nut had bent the hop window when tring to remove it... Ooops. It was straightened out and looks fine. With this in mind i am wondering if even the smallest bend has caused pressure loss hop/barrel. I dont mind too much as it was a learing curve but i wanted to get the orga barrel after christmas so was not planning to get it yet. Suppose i may have to break the bank a little more and have it over and done with. Any thought's ?

Two side notes. One. Still breaking in the kit as its just too loud to do in the house and garden at times so really struggling. May take it to the local shop and use their range if they dont mind the noise. Getting around 250fps on .25's @90psi. Still no gain at higher psi so hoping the break in will shed some light on it. "only at around 3000 rounds atm." Two. Decided to go all in on the HPA community and have a polarstar jack coming to convert my WE Mk17, after playing with hpa gives me no love for AEG anymore. Considering the spare parts and batteries I may very well get another AEG in the future just for the sake of having one. Want to make some plans for tidying the paintwork on the receivers once its all done, also got a real steel ambidextrous selector favourited. Also got some flat headed grub M3 screws coming to do the trigger job to the daytona. Currently the trigger has a long travel before it even starts pushing on the valve, so got some screws to adjust it back to the point a small flick and its off. Only really noticed how bad the travel was when i tried spamming semi auto, you would end up flicking the trigger around and never firing . Cheers

Little update, been busy and not too much to on the TNK, i did however get my Stark pistol grip. It’s outstanding, very strong and extremely comfortable. The two main modifications to make it all fit was, the drill as per for the airline and widening the spring guide slot to take the original spring. Also worth noting the spring guide needed boring out around the opening to allow any misalignment on the spring and pin to not cause any selector issues. Final fitting

My boss bought one not so long back and he swears by it. No fogging, no matter the weather and a whole lot of protection. Personally i wouldnt as i like having a little a possible in the way with aiming down sight etc.

Not too much happened for a few days, had a slight slip up with the hopup rubber. Lucky tony sent me a spare are part of my order Temporary inner barrel is cut down and in. However i did notice that thr fps is a bit weird, not sure if you can shed some light on this "profrink" ? So 80psi, .25 and 280-300 fps.. then 100psi 300-310 fps. 130psi, no change. A few things i did check, the airseal when carrier is in the receiver to barrel is not great. I can blow down the barrel, and easily lets air pass through. I moved the air rod along and it does open up fully when the cylinder opens up. Is this just a bed in thing or should i be looking out for something ? Cheers

George Something received the package ! Cheers dude, sorting the inner barrel out tomorrow. As i havent made my mind up on the rail and outer barrel i wont buy the magnus untill 100% happy.

Cheers man, little rough around the edges but its getting there Its not, just the standard hk416. I am however tryng to get my hands on a rainier arms charging handle. Really like the look of a ambidextrous, charging handle. want to replace the selector and trigger with real steel aswell. Only trouble with that is i would need to buy the entire trigger kit even if i only want the trigger. Meh ! Also didnt pop up the pics of the selector, i had to shave about 1mm off the semi auto section as it was causing the full auto shear to hold on full auto in semi .

Build log... Sorry for the image spam Start removal of material for rear valve. Removed material, functional but not tidy. Will polish up soon. IGL feed drilled ready for new pistil grip coming. "Stark-One Ar-15" Valve mock up Upper receiver rear lug removed. Hopup access hole. "So happy with this drill" Charging hangle ground down and widened for pickup. Front access removed for hopup mag feed. Also note the bolt catch has been removed.

Quick update Got to the tools Saturday , many many cuts later and had all modifications done in just over 3 hours. Had the kit locktighted to shugar and lubed up Bretty dam good. Had about 20 shots before I had to pop out and it kicks like a horse. Will report on all the work needed to get it to fit, pics of course. One thing I wanted to ask is the valve refresh time. When firing the pressure in the regulator drops , obviously .. But how much is normal? If I full auto at 100psi it would hold roughly 70psi until I let off. Cheers
