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.

Project RPK almost finished and moved to a new city

Long time no see!

I have had a longtime project to build most practical LMG for bigger mil-sim games. So naturally the RPK gives me all what I need. Its just a "big AK"

Bought this used for 50 euros. It had broken stock and internals.

Base gun is Cyma 052S with polymer furniture. I will remove the bi-pods and add an rail-system (probably the LCT Keymod one) with gripod.

Some tinkering and fixing and now its almost ready! 

Camo pattern is Finnish M05 Autumn/Winter "Frozen pattern" (or something like that)

Internals:

1. Retro Arms V2 gearbox
1. 8mm bearings
2. SHS 200% torque gears
3. Random Cylinder parts (needs to be chanced to lonex)
4. ASCU3 gen.3+
5. Ares 15t piston, 
6. Lonex POM PH
2. Old JG blue motor (this needs to be recoiled to something faster)
3. ZCI Lapped inner barrel with EIR hop
   
   Whats your favorite LMG?

I also got a new job and moved to a new city so there hasnt been happening too much in my airsoft projects.

But something new is coming all the time!

BTC Spectre for Tokyo Marui Next Gen Gearbox quickie

BTC Spectre SneakPeak


Just got some goodies from overseas! Managed to grab one straight from Blacktalon Customs!

Will be installing this next weekend and hope to do some skirmishing next Sunday in Local Pirkanmaasoft games!


Not sure yet should I rewire my unit to front or keep it as it is. Yay or nay?


You can get yours from Blacktalon Customs or some distributor. They are in huge demand so be prepared to wait long time! I got mine by adding myself to notification list and ordered one minute after I got my notice!

From BTC Homepage:

Advanced Technology
Can handle power surges up to 9000 watts and even run on car batteries!
Fully computerized and driven by a high speed PIC18F14K22 microprocessor.
Multiple internal layers of heavy copper traces for greater current capacity.
Short circuit detection and voltage spike suppression circuits to protect the controller.
Smart thermal management allows the controller to remain cool under sustained firing.

MOSFET Trigger
Eliminates damaging electrical arcing of the trigger switch contacts.
Lower resistance compared to mechanical switching, increasing motor current.
Driven by dual IRF671812PBF, a compact yet powerful next-gen MOSFET!

Dynamic Braking
Eliminates the motor spin-down time to prevent the piston from over-traveling.
Assists in keeping the piston properly reset to reduce stress on the gearbox.
Prevents double firing on semi-fire in extremely high RoF setups.
Also driven by dual IRF671812PBF MOSFETs!

Cycle Completion
Gearbox always completes the last cycle regardless of when the trigger is released.
Assists in keeping the piston properly reset to reduce stress on the gearbox.
The motor will always have the smoothest and most consistent startup.
Allows the anti-reversal latch to be removed.

Fully Configurable Fire Select
Both fire select positions can be individually configured, for a total of 64 possible configurations.
Available options for each selector position:
Semi fire
Auto fire
2 round burst
3 round burst
4 round burst
5 round burst
Semi with ramping
Burst-auto hybrid
"Semi w/ Ramping" fires in semi and switches to full auto if the trigger is rapidly tapped.
"Burst-auto hybrid" fires in burst and switches to full auto if the trigger remains held down.
Can convert any AEG to semi-only by having both selector positions set to semi fire.

Realistic RoF Control
Both fire select positions can be individually configured with a different RoF.
Every cycle runs at full speed and pauses between each shot to reduce the RoF.
Provides the most realistic feel and sound compared to any other forms of RoF reduction.

Adjustable Precocking
Precocking stops the piston in a compressed state so the next shot is near-instantaneous.
The precocking is fully adjustable and thus also compatible with short-stroked pistons.
Offers improved realism and trigger response for sniper or low RoF builds.

LiPo / LiFePO4 Monitoring
Monitors LiPo and LiFePO4 batteries to cutoff power before overdischarge occurs.
Simply set the number of cells and the controller will use the proper cutoff voltage.

Programmable Digital Fuse
Sensor-based current monitoring negates the need for a physical fuse.
Cutoff threshold fully adjustable to help protect low-output batteries from over-current damage.

Gearbox Reliability
Eliminates the trigger jam normally caused by the cutoff lever stopping at a certain position.
The cutoff lever mechanism is no longer needed, greatly reducing the chances of semi-fire related issues.
The anti-reversal latch can also be removed to make gearbox reassembly much easier.

Spectre comes with a original Deans T-Plug

Project Start: Tokyo Marui M4A1 SOCOM Next Gen. Recoil Shock

Tokyo Marui M4A1 SOCOM Next Gen. Recoil Shock Project start

Spring is finally here and our airsoft season is starting fully. I wanted to have something new and interesting to tinker around. So I was able to acquire second hand unused TM recoil M4 that has been laying in closet since 2009.

Gun in in good condition but internals need some sweet care. New TM Gun should shoot about 0.9J but this one shot only 0.5J! Overall performance is really sluggish etc. Time to open it up and upgrade this beast where it belongs!

My plan is to make my CQB-Gun that shoots about 1,2J with 0.30 BB (for the best range and accuracy). I have some SHS and Orga parts already but I will check is there anything that needs to be upgraded in TM gun. (They work really well with stock setup)

I want to keep this gun in quite basic setup externally. Something like that you can find in movie SWAT. I had G&P M500 handguard laying around and it fits really well to this classic.

G&P M500 is upgraded already wit 1200 lumen LED module so opponents will be stunned by the awesomeness of this!


I also managed to get BTC Spectre for next gen and it will arrive soon! Cant wait for it!


Some pictures of internals that are waiting for this project:

I will be keep you updated how this project progress, stay tuned!
