If you read the description, near the end it says, "These magazines are recommended for use with high quality airsoft M4 replicas like G&G, VFC, Classic Army, Tokyo Marui, and ICS. This magazine may work with other manufacturers AEG but cannot be confirmed by Airsoft GI."
So, I have a JG M4. I know it's not a "high quality" airsoft gun, but I was wondering what if these magazines will still fit into my gun and work as it supposedly should with said higher quality guns.
Can anyone answer this question for me? I would appreciate it. Thanks.
I don't know anything about the Beta Project Pmag, but my brother has some Beta Project mags for his AK74 and they don't feed very well. The bb's were jamming inside the mag. Again, I don't know if the Pmag is different but just an observation.
Unless you can find a bunch of good reviews about the Beta Projects I would recommend going with the Star 75rd Green Label Pmags instead. If you shop around you can find a box set of 10 for less than $60. I used a set for a while and they were great. The plastic felt cheap, but I only had one jam the entire time I used them. I would assume that one jam was caused by a poor quality bb rather than the mag. If you look hard they can be found dirt cheap used. I've seen them as low as $5 a mag used.
I can't say those mags will fit for sure, but the JG M4 is a pretty popular rifle and I haven't heard of them being picky about mags. JG M4's are very popular on Airsoftforums, head over there and do a search and see what turns up. It's possible someone has already tried the Beta Project mags in a JG.
There was a review of these on arnies, and they seem to have quite a problem with jamming. They probably are not the best buy. It sounds like the concensus thus far is that the actual pts pmags are all around the best.
I know that this is a zombie post but I have suggestions on how to resolve the issues. I run, almost exclusively, p-mags. I have had the same issues as everybody else and I have figured out some helpful things along the way.
1. Clean your mags. After you play swish them around in warm soapy water, rinse them and let them dry.
2. Lube your mags. I've had some success with simply spraying some silicon oil into the mag with a few bb's loaded.
3. Ammo. My friend swears by using quality bbs' in his p-mags.
4. This is a last ditch effort. I do not condone this method, if you're not careful you could destroy your mags. You could remove the cap that retains the spring and follower. This can prove to be very difficult as the cap is glued into place. Get the cap off and remove the follower. The end of the spring that the follower slips into is crimped and will still allow the mag to feed. I have done this to around 6 of my mags and all feed flawlessly. But yet again, I DO NOT CONDONE THIS AND I AM IN NO WAY RESPONSIBLE FOR WHAT YOU DO TO YOUR MAGS.
P-mags are seemingly a bargain. But you may have to put in some work. This is only for the m-4/m-16 style mags. I hope this helps.
You just have to file off the highest ridge on the front of your pmags and they will fit. I just did it for my PTS ones and they now work great. I can post pics at a later date if anyone is interested, but google should turn up some results since this is a pretty common technique.
