WTB: MGC .223 M4 Series CP-HW CARTRIDGES

Am after as many of these as I can get (max up to about 40 or 50 of them) but they MUST be working and fully functioning. Please message me with how many you have as well as a price. Please note I am in the UK so if you are selling to me from outside the UK please bare this in mind when working out postage.

If there's any confusion as to which I need please see the following post: https://mp40modelguns.forumotion.net/t3495-mgc-223-m16-xm177-m4-series-cp-hw

Thank you.

Hello Ammo

Have you asked John at www.plugfirecapgunsuk.com if he has any:?: Another option may be to use Tanio Koba M4A1 .223" cartridges. I'm sure John can confirm if these fit the HWABS MGC models.

You could also try asking forum member shazhib in Tokyo via PM if he can find the original MGC cartridges.

Hi Cerwyn.

I contacted John as well as posting here and John has some I can buy and I was able to find a supplier from Japan as well with whom I placed an order for 20 of them but the biggest problem now is I think the gun is not working correctly (so I have had to request a cancel on my order from Japan and put on hold the purchase of any until I can resolve the issue with the M4). I will post the problem in the correct place once I get home but in short the gun fires the cartridges but will not cycle to the next one in the mag (it doesn't eject the spent cartridge out the gun and instead just hangs in there by the arm). I was at it for hours last night trying to figure out what's wrong with no luck.

Hi Ammo

That's good news on the cartridges at least but not so good regarding the M4. There are a couple of simple checks you can make to identify where the problem lies

Assuming now the M4 you're buy-ing is used, first thing to check is te Chamber and Detonator Pin. All too often o2wners forget to clean these thoroughly after every firing session. So much dirt and residue builds up on the Pin especially it'll jam in cartridges stopping them extracting properly.

Next check to make is the cartridges themselves. Any dirt or corrosion inside tese will create friction reducing blow back enough to stop extraction. Are the 0 rings on the piston /firing pin in good condition ? Any splits, cuts or other damage will alllow all gas pressure to leak past the 0 ring stopping blowback.

Are the caps in good condition?

If all's well, load the cartridges ensuring the 0 rings are lubed with silicone oil or grease. This is essential.

If this doesn't sort it, assemble the cartridges and load them into the mag. Insert the mag into the gun, pull back the charging handle and release it to push the first cartridge into the chamber. Don't squeeze the trigger, pull the charging handle back sharply. The cartridge should extract and eject cleanly. If it does, release the charging handle again and repeat the process until the mag's empty. If this works properly, there's every likelyhood your cartridges need a thorough clean and possibly new 0 rings too.

Pleae let us know how that goes and we'll take it from there
