Our take:  The Special Operations Branch (SOB) 1 by Echo1 is one of their newest M5 style AEGs that is compact with the power of a full-sized AEG rifle.  Fully equipped with a Version 2 gearbox, this low-profile SMG easily shoots between 390-400 FPS (w/ 0.20g BBs), delivers a high rate of fire and can be upgraded with Version 2 aftermarket parts for a truly customized AEG.  This SMG by Echo1 is perfect for all players who want power and range loaded into a compact, lightweight submachine gun.

The SOB 1, which Echo1 designed for both indoor and outdoor fields, is modern update of the M5 series of SMGs.  It features an integrated rail system for attaching tactical accessories, but unlike other rail equipped M5 style AEGs, the Echo1 SOB 1 is equipped with a long monolithic top rail that measures 14 inches long.  This makes it easy to attach an array of aftermarket sights and scopes, with ample space to adjust for eye relief.  This submachine gun is perfect for entering buildings and turning tight corners due to its ultra compact size, which can easily be adjusted thanks to its retractable crane stock, common among many M4 AEGs.  Another great feature that sets this submachine gun apart from other M5s is its straight magazine configuration.  The SOB 1 sports an enhanced tactical look that older versions lack and is an incredible SMG for any tactical loadout!

The Echo1 SOB 1 is geared for both left and right-handed players as it comes with an ambidextrous selector switch.  Additionally, this submachine gun also includes a rubberized buttplate for improved ergonomics and a swivel sling attachment below the stock.  And thanks to its full metal build — upper receiver, outer barrel, buffer tube and rails — this AEG is extremely durable and dependable for all airsoft players.  The NEW SOB 1 Submachine Gun by Echo1 is ready for you to field and comes complete with battery, charger and TWO high capacity magazines!

Features:
- Full metal Version 2 gearbox
- Full metal outer barrel, upper receiver, buffer tube
- Integrated rail system w/ 2X rail covers
- 14-inch monolithic top rail
- Ambidextrous selector switch

5 Echo1 Airsoft Full Metal SOB 1 Airsoft AEG Submachine Gun *****
AWESOME

"I got this gun and right out of the box it dominated. All i added was a fore grip and some iron sights and I was smoking my friends. It says it shoots 400 FPS, but when I went to Ballahack Airsoft in Virginia they made us chrono our guns, and mine chronoed at 415-430 FPS. I was shocked that it was that high, but I took it.......... AND STILL DOMINATED! IF your hesitating, don't, just get this gun. I truly can tell you that there is nothing wrong with it. But unless your a hip-fire person, like the other guys, I recommend getting some sort of sight."

Great Buy!

"I had a large order through Airsoft megastore, but the main event was this SOB 1! I must say that it was exactly what I was looking for! The full metal upper receiver not only adds a level of strength, but gives the gun a nice balanced weight. It shoots hard and extremely accurate. I put a red dot sight on it, and it works beautifully. And aftermarket sight is required. If you're interested in giving up accuracy for compactness, the SOB 2 is a more compact version with a shorter barrel. However, the SOB 1 is compact enough to still be good in close quarters, with a long enough barrel to be effective at long range. At a great price, this is the best Submachine gun in the market, and something I always want to take to battle with me!"

SOB 1

"This gun is beast all the way around. It's rate of fire can easily keep enemies down and on the ground. I recommend you keep it semi automatic though to conserve your ammo. But if you have a fast trigger finger no problem. I play on field environments and even then it performs great. Where I really recommend it is at short range then I completely dominates the enemy it's high rate of fire and its comfortably level make it great a force to be trifled with. I strongly recommend you get some sights for this gun because it does not come with any at all. Also a extra mag if logical too. And I also urge you to get a mock suppressor of some sort to extend the range a little. All in all If your looking a gun that you can easily rush the enemy with as well as defending fortified positions this gun is for you."

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
