Magpul PTS Masada vs. Bushmaster ACR

A customer came in at work after hours today to show us (Jasper and I) this beauty. He shared with us some of the details and procedures about the real ACR that I have done my best to remember and add after the break.

Which one is the Magpul PTS Masada ACR AEG? Which one is the Bushmaster ACR? Its all in the details…


I’ve taped over the serial number of the ACR owner’s gun. For fun, I did the same to the PTS Masada on the same place where that serial number is on the real ACR.


I’ll give you a few hints – the real ACR is an non-restricted firearm as per Canadian firearm rules. It does not have any prohibited parts (like a suppressor). It is illegal for civilians in Canada to own firearms that are capable of full-auto fire.
Honestly, PTS did a really good job with the Masada AEG – overall dimensions and texture of materials feels spot on. Weight is slightly more front heavy on the real ACR, thanks to the longer, match barrel that this user has. Pistol grip is slightly fatter on the PTS Masada, as a result of having to fit a motor inside the pistol grip. Other than that…

Enough of my thoughts – do you want to take a look at the inner workings of a real ACR? Pictures after the break… and bonus intel about something new that relates to the Masada/ACR in Airsoft at the very bottom.

LCT AK 104 Front End

so pretty.

so pretty.

Anyone who knows me (or sees me on the field) will tell you that I’m pretty big on externals. I love tinkering with things like rails, stocks, optics, illumination, lasers, etc. Not everything gives me an in-game advantage (if anything, some of it is just effectively dead weight) but boy, does it look cool.

After the break, a quick look at what is quickly becoming one of my favorite AEGs, both externally and internally – my LCT AK 104. Specifically, the front end.

Tokyo Marui MP7A1 GBB & Action Loading Muzzle

Quick preface: If you’re looking for more info and a shooting demo of the TM MP7, you’re reading the wrong article. If this is what you’re looking for, I suggest you check out (some of) the videos on the Marui MP7 GBB done by a guy going by username KhanSeb on YouTube – he does some very nice shooting demos of many, many Airsoft guns. I’m fairly certain he’s got a few other clips featuring the Tokyo Marui MP7, both demonstrations as well as game play footage as well.

My KWA MP7 GBB is a SMG that I’ve come to respect after shooting it. When Tokyo Marui released their MP7 GBB late last year, I was interested to see how it would be before picking up my KWA. I only recently had a chance to hold one myself, as a few arrived at work a few months ago.

The TM MP7 GBB is in fact a very fun gun to shoot. The kick is noticeably more substantial than the KWA’s light blow back action. Though it doesn’t seem to be quite of an efficient gas system as in the KWA model, I’m hoping to get to try out the legendary TM GBB accuracy and range as it performs in this gun one day soon (I mean, TM puts a similar hop up design into their GBB’s as is in the venerable VSR-10 sniper rifle… how can that possibly go bad?). The space that I plink in at work during down time is not nearly long enough for the hop up to even kick in.

This first photo is the best look I’ve gotten inside the hop up unit thus far (there are video clips all over YouTube demonstrating how to expose the craftily hidden hop up adjustment dial, but asides from that, this angle is the only other look I’ve personally had at the Tokyo Marui MP7 hop up chamber). I didn’t want to take it apart any further than this as this is a gun for sale at work. As much as I want to tinker with it, I’ll leave that up to the person who buys it… oh wait, that might be me (if there’s still one for sale, when I can afford it).


I spent some time at work taking apart the bolt carrier group in the Tokyo Marui MP7, as our demo gun had a blown out loading nozzle – the following article is a result of the photos I took and observations I made while doing that repair.

Guarder TM MEU Metal Kit

I ordered a Guarder Metal Slide and Frame for Tokyo Marui MEU with TRP Markings through work. This is my first complete aftermarket 1911 metal frame installation project. I’ve retrofitted entire 1911 GBB’s into new OEM slides and frames before, and even slides and frames from other gun manufacturers (not to mention doing the same job on a few Marui/KJ/Prime P226N and countless TM/PGC/Guarder Glocks) But… I just wasn’t prepared for the headaches (plural, not singular) resulting from trying to put this one together.


Though it may look and feel nice now, it turned out that the lower didn’t fit together nearly as well as I thought it should. With hours of sanding, polishing, testing and repeating that process, I think I have finally worked it all out. Read on for my thoughts on this process.

News: Magpul PTS RM4 ERG Series


According to an article on Popular Airsoft, Magpul PTS will soon release its new PTS RM4 ERG (Electric Recoil Gun) system in August.

This is the first time I’ve heard of it, but the RM4 seems to be Magpul PTS’s version of the Tokyo Marui Next-Gen AEG platform, with a recoil/shock system and a functioning bolt catch that locks the gearbox on an empty magazine.  It appears that the RM4 will be “co-distributed” by KWA, although whether this means KWA is in fact the OEM for this is unclear.

The most significant difference between the RM4 and the Tokyo Marui Next-Gen AEG is the ability of the RM4 to take normal AEG magazines, unlike the Next-Gen TM which only accepts Next-Gen TM magazines without an adaptor. Using normal AEG magazines will, however, not enable the functioning bolt catch, which is to be expected. The magazines themselves seem to operate the functioning bolt catch differently as well, operating with what appears to be an elongated follower that somehow locks the gearbox, presumably through the hop chamber? Interesting. It’s certainly different from the lever mounted in the rear of the Next-Gen TM and PTW magazines.

I presume (though I could be wrong) that the “shock” will come from a weight moving back and forth in the buffer tube, similar to the TM design.

Still unknown at this point how much of the gearbox is proprietary (I’m presuming most of it will be, since most of the TM gearbox is proprietary). I’m hoping Magpul PTS has found a way to keep most of it V2 compatible, but I presume time will tell. Otherwise, this is another new platform and another new attempt to move airsoft technology forward, which is always a good thing in my book.
