First, I built my SPR from the parts, not from purchasing the premade unit here. So I ended up with the kit so I was able to put the quick swap function to the test. ALSO I just received this and have not yet put it through its full paces for a season. This is also why I give it a neutral rating of 3
This is 15lbs of solid gun!
The mag well doesn't seem to like the Magpul hi-caps, but so far it loves my other mags. Though it seems like it will take some breaking in to make it a smooth action.
The sound of the gearbox is crisp and strong, but i have yet to put a full 1000 rounds through it yet.
I personally dislike heatshield battery compartments but the Masada platform makes it simpler and easier than most other AEGs i have personally wrestled with. I do have to say the Long Handguard does make for a better battery space.
It also looks pretty cool by itself with the CQC barrel tucked just inside it.
Also, I have a couple of barrel extensions (suppressors) and they seem to slide right into the thing no problem, so no need to detach/reattach it, BUT that is likely not a typical result.
The thing that had me struggling for hours over was getting the stock installed. THIS unit has had that work done for you but because I bought mine as a seperate unit the top pin connecting the stock to the upper receiver did NOT connect flush. I had to disassemble the stock and take the dremmel to the stock AND the upper receiver to get the pin to cooperate. This was an OBNOXIOUS step but did not seem to run a real risk of compromising the integrity of the plastic of the stock or metal of the upper receiver.
The real complaint i have for this thing is the sling mounting options. The swivel mounts WORK just fine, and the unit comes with strap sling attachment points too. But i find it inconvenient to have to install two swivel mounts to take proper advantage. Magpul has plenty of other products that do a better job out of box, so I'm not holding this one against them.
However I would say that if you're the type to sling their rifle like i am, it is in your best interest to look at getting the sling bracket for the stock. (at this time they are out of stock)
Finally, the 18 inch barrel i got came with a black metal flashhider (m16 birdcage style) that I could remove and replace with most of my other barrel attachments. It has a nifty little feature of a triple washered o-ring bracket which i think makes for a better seating for those who want to throw a supressor on. I only point this out because the 11 inch barrel my Masada came with had a misaligned plastic orange flash hider that is firmly glued in place.
Long Handguard is more spacious for batteries.
MOE rail attachments seat perfectly
Quick swap system works as advertised.
Whole unit is solid as hell!
Barrel extensions become truly aesthetic but they seat good and solid.
Monolithic front sight is annoying and scratches the paint.
Stock is stiff an relatively uncomfortable. Also is painfully slow to adjust (though adjustments are solid)
Seats but hates Magpul hi-caps (proprietary con)
Stock MAY be a pain to install (not for this premade unit...unless they ship the stock detached)
