Our take:  The NEW Proline M15 ARMS S.I.R. System AEG is fully licensed by Armalite, the original manufacturer of the AR-15.  From the outer barrel to the buffer tube, this Armalite M15 AEG is made completely of metal!  This gives it realistic weight, making it a convincing and authentic 1:1 scale replica.  Its main appeal goes to the ARMS S.I.R. rail system, which has been one of the most popular systems used in airsoft and appears in modern first-person-shooter video games.  With the advantage of adding additional aftermarket accessories present, you can also add a slew of red dot sights and magnified scopes.

When it comes to internals, a full metal gearbox (with 8mm double bushings and spring guide with bearings) is compatible with aftermarket Version 2 parts, allowing this full metal M4 AEG to shoot up to about 410 FPS with 0.20g seamless BBs.  Unlike other front-wired M4 AEGs, the ASG M15 airsoft rifle is equipped with an easy access battery compartment that will fit a 9.6V nunchuck battery, without having to remove the handguard.  If you’re looking for a full metal M4 AEG with realistic weight, hard-hitting FPS, and officially licensed trademarks for added authenticity, the ASG Armalite M15 ARMS S.I.R. System AEG is a must-have airsoft rifle for all players!

Features:
- Officially licensed by Armalite and A.R.M.S.
- Licensed S.I.R. rail system with trademarks
- Full metal receivers, barrel, buffer tube
- Version 2 gearbox w/ 8mm double bushings

- Retractable LMT sopmod crane stock
- Built-in metal adapter plate for slings
- Adjustable front and (flip-up) rear sights

Ammo type:  Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs.  For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Package includes:  Airsoft rifle, 350rd hicap magazine, tactical foregrip, elevation adjustment tool, instruction manual

Color:  BLACK

Battery Charger Recommendation:  Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery(overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly).  Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.

5 ASG Proline Armalite M15 ARMS S.I.R. System M4 Airsoft AEG Rifle *****
Absolutely amazing

"I was very pleased when I took this gun out and shot it. For the price there is no better airsoft gun. To be better than this you would have to spend probably $400. The only downside is the battery compartment is a little difficult to open, nearly impossible during battle, however the battery it comes with is very excellent and lasted me all day with moderate usage and still had plenty afterword to play around with."

5 ASG Proline Armalite M15 ARMS S.I.R. System M4 Airsoft AEG Rifle *****
Great gun

"probably the best m4 at the $200 range! very affordable, good externals and internals, and shoots amazingly. Only real complaint is that the anti-reversal latch broke and it started double feeding, but wasn't too hard to fix. The bolt catch also broke, but no big deal, because i can still access the hopup chamber, and the bolt will still go back and close. the magazine catch also is a little loose, so the mags wobble a bit. overall totally recommend this gun, great for the price, very durable externally and internally, and is awesome overall"

The gun

"Ok let's start off with the gun look,and feels great. When I first got this gun mag was always lose. After the first game the mag broke. It rof, and fps is good, but the accuracy sucks. At 50feet the spread is about 8inches. So buy a better barrel for it,but for a gun that is under $200 not bad. "

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
