"First off, I'll summarize. 4 out of 5 stars. Nice externals, very nice internals. Effective hop-up, good range & accuracy. Grand in scale.
Now, the outside is nice; featuring steel receivers, trigger, trigger guard, mag release, bipod and gas block. The handguard and buttstock are wood. The piece that connects the receiver and stock together is nice, beefier than most. While it isn't made of steel, it is decently thick and has supports. However, the bottom screw hole on my exact gun was stripped out, so the stock is wobbly as the screw will not tighten all the way. This does not effect performance.
The upper half of the handguard is a little loose, but this doesn't effect performance either; it just rattles a bit.
The barrel itself is aluminum, and the front sight & flash hider are a cheap pot metal. The front sight was already missing a small piece, and both the hider and sight are loose. (I expect them to shatter completely sometime soon)
The internals are pleasant. It has a high-torque motor for quick fire rates if you like that sort of thing. The hopup is very effective, with small adjustments making big changes in range/accuracy. The hopup is metal, as well. I can't seem to remember the mm of the gearbox.
The accuracy is nice up to 100ft, but the grouping at such a range isn't terribly consistent.
Also, my shipping label listed this as 6.5lbs, and my own scale listed it at 9.5lbs.
But it you were to ask me, I would say that it is even heavier. I really do not recommend this for small people or children. I, myself, am small in stature and it is a tad tiring wielding it.
Now for the real meat of the review, the things I don't like:
Front sight and flash hider are made with dirt-cheap metal. They will break quickly.
The charging handle has a small arm on the bottom to keep in on track. It in fact does not do its job, comes off the track, and makes the movement of the bolt... not-so smooth. But it does not interfere with usage, just kinda makes it grind and scrape.
The battery goes in the stock. The isn't much room at all. Either use an 8.4v brick, or a peq battery because, with the rather rigid wires, it isn't the easiest to fit either inside. Or use woodworking tools and carve yourself some more space!
The battery cover attaches with two screws. Quick battery changes ain't in your future.
This gun is heavy as sin.
The big ol' banana mag gets in the way when using the bipod. It's fine while you are firing, but if you try to rest the gun down, the mag gets in the way and the whole gun tilts.
By hey, at least you look like a baller holding this with a cigar hanging from your mouth.
So that's what I have to say about this piece. You may take my review with a grain of salt; I haven't game-tested this yet, so I have no idea how it stands to abuse.
Thanks for reading, though.
"I've had one of these for a few months now, and have made a few observations about this particular RPK.
First, on initial chrono, bone stock, my Redstar was running 410 FPS with .20g bbs. The stock 9.6v battery is more than sufficient to run the gun, however if you plan on buying an upgraded battery you'll need to get yourself a PEQ box battery, due to the weird shape of the stock/battery compartment.
The stock hopup chamber is metal, and the stock bucking/nub combo is OK. You can definitely reach out and touch someone with this rifle. That being said, it's not terribly consistent in the groupings.
I recently upgraded my Redstar with a Madbull Fishbone bucking and Madbull 500mm tightbore. This has bumped the FPS considerably into the 450 FPS range, from around 440 to 455 FPS, in addition to making this thing a tack driver. I've read online that it's possible to run up to a 590mm tightbore in this weapon without having to use a boreup kit, however I am unsure of this personally.
OK, so now on to the cons of this weapon;
In my first real OP with the gun, I managed to break the front sight, lose the rear leaf sight, and break the front sight post sleeve that goes around the outer barrel. Those parts are made of pot metal, not a decent steel like the rest of the weapon. However this is mitigated by the gun having the ability to use an AK side rail mount, though the optic will sit quite high off the receiver.
The front end is a bit wobbly after use, most likely because unlike regular AKs, there's just one pin through the trunion holding the front end and receiver together. It's not really a pain to take apart, and it make accessing the inner barrel and hopup almost a breeze.
Come with a 9.6v battery from the factory.
Easy to disassemble and upgrade the inner barrel and get into the gearbox.
Drum mag makes this gun beast.
Doesn't seem to like using regular AK mags until you've broken it in.
Stock and front end may start to wobble on you a bit.
Factory barrel and hop bucking/nub doesn't give the best groupings.
Front sight assembly is pot metal, and will probably crack/break. (This can be fixed with creative use of JB Weld and hope)
"so ive had mine for about halve a year now, it worked fantastically until about a month ago, the metal that is used for the sight isnt very good and my sight split in halve around the barrel and it is very difficult to find a new one, now the charging handle looks like its going to come off. but the major down side to having the front sight broken id that you cant use your bipod without it. although if you think about it its not to terrible because you have a long barreled ak!:D besides that the range and FPS are really nice and the quality for the most part is really nice!
