Specna Arms RRA Edge series, picture heavy

Specna Arms SA-E10 RRA Edge Half-Tan

TLDR; Really good AR-15 style AEG that offers better performance than most premium guns in the market for the dirt-cheap price range. Shimming is bad, fix it before putting big springs in.

Long version:

This time I will be making a technical review of the New Specna Arms RRA SA-E10 Edge and its Orion gearbox.

I got my hands to a  couple of freshly released Specna Arms (SA in future) Edge that we are using as rental guns in our own www.pew-pew.fi games. The idea is to offer new players the possibility to use similar tools as more advanced players and starting a hobby isn't lacking from that front.

Specna Arms is a Polish brand that is closely tied to the popular airsoft store Gunfire. Guns are OEMd by factory (Mainland China and Hong Kong) that provides few other famous brands like E&C, ZCI, etc. (yeah yeah, this is a long story but let's keep it short). SA has been really popular in Europe for the last few years and they are starting to open the market in the US as we speak.

There are few different line-ups from SA and this model represents the highest end Edge line, you can read more about those other lines from manufacturers own web-site.

Features (I was lazy and loaned the list from Evike.com)

• Aluminum alloy upper and lower receiver with deep laser engraved Rock River Arms (RRA) logos

• Scratch and weather resistant nano-coating

• Nylon fiber furniture

• GATE X-ASR Mosfet

• ESA™ quick spring change system allows the spring to be changed without the need to disassemble your gun

• Rotary type hopup with 6.03mm tight bore barrel

• 380 fps spring pre-installed from factory, optional 310 fps (M90) spring included to reduce muzzle velocity

• New Orion Gearbox with reinforced shell and internals

Gun came with two good quality midcap mags and front grip in a well-packed package.

Externals

Have to say that bang for the buck/euro is with Specna Arms right now. Quality of outer parts would be well compared to G&P.  The receiver is top-notch and rails are okayish. 

Kind of loudener (heavy AF)  and normal -14 mm. threads

Adjustable and folding front-sight

Adjustable BUIS 

Plenty of battery space in adjustable Crane-style stock

That shiny thing is just a sticker and can be removed! :)

Gearbox / Nozzle Alignment is spot on, no wonder why the gun is so accurate

Lipo-Buffer tube and steel end-plate

4 Screws at the bottom of the pistol grip

QD Bottom plate, add some thread lock to the adjustment screw

Steel Body pins

Orion Gearbox

Specna Arms Orion Gearbox is based on VFC style V2 design. It has 8 mm. steel ball bearings and proper reinforcements in good places. Cylinder window corners have already been rounded from the factory. Thus preventing the front end of the gearbox cracking.

EDGE series guns do include Quick Change Spring system that is really a quick one. take off the stock, use a long screwdriver to remove the buffer tube assembly and you'll be able to access the spring. This takes 2 minutes at most!

Everything "TM Standard" so getting some proper good parts is not a problem. Gate Titan, BTC Mosfets, etc. are easy to install to this gearbox

What can be found in gearbox:

• Reinforced QD V2 Gearbox, "TM Compatible"
• 8 mm. Steel Ball Bearing (not glued)
• 16AWG Silverish low-resistance wiring
• GATE X-ASR Mosfet with t-plug (Deans), Mini connector adapter comes with the gun)
• Sintered 18:1 Steel Gears with delayer chip
• Nylon bodied 14,5t Hardened steel racked piston, rack glued
• Alu Piston head with double o-rings and bearings
• Total 29g ph+piston
• Alu Air-seal Nozzle with o-ring
• Alu Cylinder head with double o-rings
• Alu Cylinder with proper porting
• QD Spring guide with polymer shaft and steel frame
• Good tappet plate and stiff tappet-spring (no midcap syndrome)
• Basic Steel ARL
• Basic metal Cut-off lever
• Basic trigger contacts and assembly
• Steel Gearbox Screws
• 26-28TPA Ish Motor (Magnets are similar as in Krytac 30k), no bearings on axel shaft
• Well meshing steel pinion gear

On the hopup side, you'll get a plastic Prowin-copy rotary unit that works. It's not Maxx ME but there is no immediate need to change that.

So, pretty nice setup and the best things are. The angle of engagement is fixed from the factory, the rack is glued already and piston head has thread lock in it!!!

Notice the hole for manual ARL Release and slot for wires

QD Spring guide

Double o-ringed Alu-piston head

Mass for the piston is 29g. and 1.0 magic units

Fixed AoE! (Angle of Engagement)

Double O-ringed Alu-Cylinder head, Fitment between nozzle and CH is ok

The rubber pad is well attached and a tad taller than in some other brands models. Thus helping with the AoE

Bonded Neo-magnets, not as strong as normal Neo but works

BONDED NEODYMIUM IRON BORON (NDFEB) MAGNETS

​Bonded Neodymium magnets are manufactured through the compression process. This process involves mixing neodymium powder with epoxy as a binder and pressing it into a die cavity with no magnetic field, thus making these magnets Isotropic. Pressed parts are then placed into the oven for curing. Compression bonded neodymium magnets are an excellent choice over other magnet types (sintered neodymium, sintered samarium cobalt, and hard ferrites) that have limits to some shapes that compression bonded magnets do not have. With their high energy product reaching up to 12 MGOe it makes them ideal for many applications requiring high magnetic strength and tight tolerances. Since no magnetic field is applied during the compression the finished product can be magnetized in any direction. Having epoxy as a binder in the manufacturing process for compression bonded magnets makes the magnets resistant to most industrial automotive fluids. With relative low tooling cost and quick turnaround compression bonded neodymium magnets are the choice for a wide variety of applications. The final product can be epoxy coated for durability and more resistant to corrosion.
