SKU: M3181AB DBoysOut of stock


310 FPS DBoys Customizable M4 RIS Grenadier Polymer AEG Airsoft Rifle

Our take: Just arrived is the all-new 2013 production-run model DBoys custom M4 RIS fully automatic AEG rifle PACKAGE, complete with a slew of add-ons and accessories. This is the newest and best DBoys M4 RIS AEG rifle package put together by DBoys thus far, with improved build quality, improved reliability, and of course, improved performance over the 2011-2012 models; as a result, it is also one of the most highly anticipated new arrivals for custom M4 AEG rifles under $100, and is finally in stock at Airsoft Megastore. If you're looking for a modern, high performance DBoys airsoft rifle, this custom M4 AEG rifle is a must have.

The base BI-3181 features a high-speed motor pre-installed from DBoys, the manufacturer, along with a high-power polymer gearbox for the best balance between value and performance on the market. We have chronograph verified this custom M4 AEG rifle to shoot on average at 260-300 FPS with 0.12g seamless performance BBs, hitting top figures of 311-312 FPS! Surprisingly, for the DBoys M4 3181 model, the rate of fire stays quite good at a more-than-respectable 650-700+ rounds per minute, even despite the bump in power for this year's new production run model. The custom DBoys M4 3181 rifle package is sure to out shoot and outlast the competitors at a fraction of their cost!

The additional launcher unit that comes along with the DBoys airsoft rifle is easily mountable onto the lower hand guard, which is similar to the the Stryke Full Metal M4 CQB 7-inch Free Float Rail System, and performs much like a high-powered shotgun unit, bursting a single BB with every shot at velocities upwards of 300 FPS.

The full DBoys Airsoft Custom package includes:

- M4 RIS AEG fully automatic rifle w/ rail system, removable carry handle & standard retractable LE-style [Law Enforcement] stock

- Tactical [removable] forward grip for maximum stability

- PEQ Box for easy battery mounting/storage

- Alternate M4A1 Carbine style hand guard (interchangeable with standard RIS)

- Tactical launcher unit with mount

- Tactical BB speedloader

- Not one, there are 2 standard magazines included

- Alternate rear crane stock (interchangeable with standard LE stock)

- Standard tactical sling

- Rechargeable 8.4v battery and standard wall charger (the purchase of a smart charger is recommended)

In total, this is a 12-piece custom airsoft package that is selling for less than the price of most SINGLE M4 AEGs on the market, and is therefore a tremendous value!

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.

Battery Charger Recommendation: Although this fully automatic DBoys airsoft rifle comes with a standard wall charger to charge the battery, 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.
