    A lovely little G&G MP5A4 with blowback polymer body. Very consistent chrono readings of around 320 fps +-5 fps. I purchased this 2nd hand as a backup gun and I have only personally skirmished it once to test it out however I'm parting with it as it's a little bit too small for my hands and I have recently gained a new RIF. The gun has some small signs of wear and tear however they have been covered up by the previous owner with a bit of paint and it looks good. Included will be a mix of 16 midcaps/lowcaps ( I can't remember how much of each). Body is polymer and the stock is a full stock allowing for a large amount of different batteries. It is wired to big tamiya however I can included a big tamiya to small tamiya adapter if needed. The only issue I have found with the gun is that inside the stock there is a tamiya connection which connects the trigger assembly to the longer bit of wire which runs into the stock which includes the fuse and etc. On that middle connection one of the pins is a little bit loose and likes to wiggle itself out of the plastic tamiya head. I found that usually just pushing it back into the connector fixes it but down the line I would recommended installing a new one for peace of mind. Will calculate shipping on offer if needed. Any questions or any offers let me know

    Had a response from PB today saying that it's very rarely that they receive them firing them hot. I take it they come from Taiwangun then and they do the downgrade for PB as their "low" option (310). If the airseal work doesn't help significantly what strength of spring would you recommend?

    Sorry I should of clarified. I was using a garden 40-50m long and it's dropping around 30m. Increasing the hop anymore just causes a jam and I can't overhop 0.28 at all which should be somewhat possible. The gun seems to cycle fine just doesn't have the power. Last time when I did chrono it did seem to have a 15 fps deviation too. I think cracking it open and checking airseals and putting a oring nozzle on first is a good starting point Also I'm using a 7.4 turnigy lipo from hobbyking. 1500mah.

    Been giving a better try today at shooting at a range of 40-50 metres using 0.28. Gun is definitely struggling a bit. I don't currently have my chrono to check but it's obvious that the power is not where it needs to be. I have a feeling patrol base most likely cuts more off the spring to be "safe" instead of trying to get to the ideal power. I have ordered some new o rings and a o ring nozzle to see if there is an issue with the airseal first. Will then check the chrono before deciding if it needs a new spring. Will let you know how it goes.

    Cheers guys, Ill do the basic upgrade for the time being of the ML bucking and nub. Ill run it for a few days and see how it goes. The external quality of the RIF is actually unreal for the price point and I am led to believe that the internals are very good too.

    Hello, Recently my CM048m order from Patrol Base arrived. It's a Christmas present to me but I gave it a quick test fire and fps check before it gets wrapped up. With the hop fully off it is firing 0.2g at a max of 310fps. Does this seem a bit low or do you think that's about right? I will get round to upgrading the bucking, nub and barrel in the future as standard so hopefully that will help. Cheers

    CM048m on my way for Christmas. Any recommendations or ideas on what to do to it?

      for a classic style ak something like this: https://www.patrolbase.co.uk/cyma-ak-svd-sling?pv=5031

       

      if you search the likes of amazon you'll find reproduction and (claimed at least) surplus ones, not particularly fancy but means you don't have to constantly be carrying the gun.

       

      if you're looking for a mode modern/tacticool setup then can't really help too much, only modern style sling i've run on an ak was the vickers tacitcl/blue force gear one which is a neat setup but has the pricetag to match.

      I agree with the above advice 100%.  For a sling I have bought an AK sling from Ant Supplies for years.  I used to soak the leather tabs in leather food for a few days, but the new ones are some kind of synthetic material.  

       

      All but two rifs have one fitted.  That means that I must have spent about £150 on bloody slings...

      If you are keen, a new hop rubber and inner barrel is fine, the hop itself is a nice metal unit.  

       

      I've a couple of 4 series CYMAs, they are a cracking rifle. 

       

      Many a filthy capitalist has met his plastic death on their account.  They are snappy enough to leave the standard motor in situ.

    Pretty much, find the latch, hook it and pull down.
  11. JVacation
    Hey mate, Double check your motor orientation, flow of positive / negative from battery. Also check the AR latch.
  12. JVacation
    Wouldn't worry about it too much, Aslong as it sounds good the lube should be doing its job. Majority of stock guns are not greatly lubed from the factory however they are usually using a thick heavy grease and lots of it with the aim of trying to make it be as "long lasting" as possible. My advice is to only relube it when you are going to have to open the gearbox at some point.
  13. JVacation
    Most likely a bb blockage causing the piston to chew a little bit Is the Umarex the ones that are manufactured by VFC? if so the exterior wise you will struggle to find something as close to the real thing. Internals from VFC can always be a pain though
  14. JVacation
    You can also get mlock qd points, I always like a bit of cord or a zip tie myself though. Glad you enjoyed the gun!
  15. JVacation
    Remember that fps is not important, it's all about joules and if the weight is hoppable. Keep the gun stock for a month I would say when you want to make changes chuck in a ML Yellow and keep the stock barrel as you shouldn't need to trim the lip. After a while upgrade the barrel to a stainless steel one - ZCI are very good for the price however you will most likely need to trip the lip. To do this use a disposable razor, put it on a spare barrel and just take a tiny bit off each time. Make sure to do the drop test in the hop up frequently when shaving the material so you stop just as it let's the bb drop down into the hopup without getting caught.
  16. JVacation
    0.25s will hop 100% - 0.28s are better and the go to but not 100% sure if they are hoppable with the stock rubber - I am currently running 0.25s despite having a ML Yellow ZCI barrel because the site I went to that was all they had... It's also important to know what type of site you go to. 0.28s are usually better outside and for distance however in cqb you will be suprised how well a 0.20 can perform If you want to upgrade or anything in the future let us know.
  17. JVacation
    You will be happy with it! I am thinking about putting an longer innerbarrel in mine soon and covering it with a either a new handguard or suppressor

    @RostokMcSpoons Bit of a guide for the different types of DE M90: 4 is polymer 6 is metal with a forged style body 7 is metal with a milled style body 8 is a different more TM spec body with a Geissele style handguard and a different stock For the M904s: The length varies with the letter A-D have metal handguards E, F and H have M4 stocks G, L and R have the PDW style stock. R and H have suppressors. G and E have different grips from the rest.

    Just had a look and it does seem like it has the same issue as you have mentioned. Fatboy40 says it shouldn't cause any issues and hasn't had any. I would however recommend going for a new barrel. @ak2m4 have maple leaf barrels which should be the best possible fit for the rubber and he might have some more zci barrels soon which are cheaper and may have a tiny bit better performance than the ML ones. I've done a lot of testing with my m904 and finally have it to where I want it. Recently I found a bit of an air leak between my zci hopup and the casing which swapping back to the stock one eliminated and boosted my fps.
  22. JVacation
    Have you tested the gun with it fully built? It may not be a huge issue. I am running a zci 229mm which seems to be fine however the lips need trimming for reliable feeding. It is also possible your hopup rubber is a anomaly and is a bit different to the rest.
  23. JVacation
    Did someone say DE M904 and keep the extra £300?
  24. JVacation
    @Fatboy40it's also a cactus jack version of the m904. I believe there are 3 companies currently "making" the same gun. I've noticed a bit of a drop in my fps lately too. Especially with the heavier ammo. Shooting about 0.88j on 28s but 1j on 20s. Let me know how you get on with the spring. Are you still running your oem inner barrel?
  25. JVacation
    DE have different stock options in the works. Think a folding stock is coming out soon.
