Sounds painful/damn right dangerous to be one of your friends on the opposing team...

I think i have found one possible cause of the jams. Its the hammer. The return spring isnt quite up to pulling it back everytime. Would there be an issue in filing down this corner in the hammer? Its already showing wear.

New O-rings arrived (3 weeks early from china, it wasnt through UPS). Fitted fine, and fires much better. the old o-ring as said in the linked review is just a bit too big, it forced gas out the back of the slide to the point you could feel it on your hand when firing. now though, this effect is much lessened. I have also removed the rocket valve from the top of the mag which leaked after firing. lubed up the seals and refitted. it now holds black gas and ultrair without issue. all mags, without firing have held gas for the last couple of weeks too. The gun however still has slide issues, it rarely goes far enough back to lock on empty (though does go far enough to cycle) and every now and then it jams. the only solution i can think of is to sand down the runners ever so slightly, as that i think that is the cause. nervous to do though, never done that before and i dont want to make it worse xD. Open to suggestions to why else the slide would jam up after firing? Its swimming in lubrication at this point. i love the look and feel of the thing to give up on it just yet I have another 9 of the aftermarket O-rings, if anyone else also wanted to do this swap.

Howd this go couldnt make this one

TM did a luger?

so a totally unbiased review of the specna arms mk18 2.0 soon?

Will bare in mind. Im not going to tinker any more until i fit the replacement o-ring. But i think it would help the slide move more freely.

Piston is a solid piece. Had it fully appart yesterday. Well except for the trigger assembly

A thread for those who wanted a modern Russian sidearm, but have only the option of Raptors’ first foray into GBB pistols. On receipt mine looked well and truly greased with some sort of thick lubricant which covered all the parts. I assume this is for transportation, as the slide, although covered in slime, did not rack easy at all. The stiff slide seems to be more of an issue caused by tolerances. There is next to no wobble in the slide, it is very much pinched between the runners. I found that racking it by hand for a while loosens it a little. This could be a case where it needs to bed in, but it does not take long for the silicon oil to be blasted out and have the slide jam once again. I wish I looked at the runners of the slide before firing the gnu, but it almost like there are chips of metal missing from it, but this could be from manufacturing though. As for blowing back, the cylinder doesn’t fully reset, the springs are far too weak and the fitment far too tight. This is evident by the back-blast of gas you get when firing. It does seem to move enough to cycle bb’s though (only when the slide has enough strength to get past its own friction however). A thread on arnies goes through a fix for this in some detail (https://arniesairsoft.co.uk/forums/index.php?/topic/218851-raptor-mp-443-pya-grach/). Overall, I think this guy had a better model than mine, but his solution on swapping the O-ring from within this part seems hopeful. His measurements of 15mmODx1.8mmCS 70D are mentioned and I have 10 of these en-route from china off eBay as linked by @Iceni. Due mid may, I will update if there is an improvement. The trigger pull is long. The reset and break point are both in the last 3mm of trigger pull. This seems an odd decision, possibly this was done to speed up development or to simplify the design? The safety is horribly stiff. It works, but with the stiffness and the trigger pull being so long, I can’t imagine I would ever use the safety, especially as you need to manually cock it. The magazines were equally slimy, two of which holding a tiny amount of gas on delivery. It has taken basically a whole Ultrair 570ml bottle of gas to refill and fire out to A) clear the gunk from inside and B) get the seals to bed in. The mist that fired out was immense, can only describe it as a teenager’s vape pen cloud. Once that settled down, they generally seemed to hold with all three of my mags managing to hold enough gas and fire over 25 times this morning, around 18 hours after filling. Though on one you could just about hear a slow leak from the refill valve, a thing that had stopped by the morning, I guess it self-righted or the pressure settled. The magazines though I think suffer BADLY from freezing. The top valve always seem to leak for a short while after firing only a couple of shots (not from the nipple part). If you fire too many and it risks venting. Nuprol 4.0 black gas just instantly vents on the first trigger pull. I have ordered a valve key thing from firesupport to see if they need a tighten or not, but this seems to be a definite weak spot in the design. The paintwork on the gnu is thin, and it doesn’t take long for scratches to show. This isn’t necessarily a bad thing, just something to be aware of. Sadly, I lack a chrono or a big garden, so I cannot report on fps or range. It does fire bb’s but with that extra strain it fires maybe 18 of them before the slide gets stuck half way. I am very tempted to take a file to the runners, but that is very much a last ditched effort to get it reliable.

Tbh if you think of the selling fee as VAT then its kinda ok? i agree it should be accounted for when naming your price. want £10 for it? place the advert for £11 or £11.50. there are plenty of calculators on google work working that stuff out.

Mtp does work in tall dry grass. For UK woodlands not so much. Digi flora or tiger is way better. Not as bad as ucp though. Saw a dude running that and he may as well have been glowing

i dont know if it would help, but i have this bookmarked as a fall back ukara fill in? assuming that is the issue? https://www.onlyairsoft.com/product/country-cover-club-re-enactment-membership-insurance/ though buying ukara kinda removes the idea behind it in my opinion? personally i wonder if its something up with the paperwork? as long as your ukara was valid at time of purchase it should be fine i'd hope

ups are an american company? so maybe its in the american date format. soooo 4th of july?

got this, and fits my cap perfect with no cutting needed, genious idea. missus quipped that if she were to play she would want one as doesnt like the helmets... so one step closer to getting her to come play since the stag/hen do shooting eachother...

tbh, the stock feels solid, and only comes off if i hold the lever, i doubt i'll adjust it too often in game im just glad it got delivered and sounds like it fired well. chrono sheet is a solid 345fps too thanks for letting me know what it was though. it looks a little like an antireversal latch (in my inexperienced mind for teching) so was a little confused. the grach came with one leaky mag from the bottom valve. the two spares seem to hold (they both came with enough pressure to just about cycle once) but i have run out of gas, so i cannot check further. slide feels very stiff though, may need some fettling

if i hold the lever, yes

thanks, no spring there, i guess thats why it was loose and jamming the stock. seems to work ok without it at the moment though. casualty from the spring chamge i guess?

Well guys. My journey on this has ended. It has arrived by UPS. Order placed on the 1st of march. UPS collecting it on the 4th. Taxes paid on the 9th.... Ukara expired on the 27th. Delivered 7th april. It appears to have not been opened... the raptor mp443 is hella lubey xD And the mp5 retractable butt stock wouldnt come out so i removed the back plate and this fell out. No idea where it was. But it works now. Fire pretty nice too.

the next 3 hours are going to be poorly focused on work, and more on the schrodingers ups delivery

mhm, mine made it to the northampton depot, so, if true, it should be on its way 🤞
