ASG DSA Inc. Licensed SA-58 OSW Proline Full Metal Airsoft AEG Rifle

One thing modern advances in weapons technology has taught us is that (unlike in WWII) a single weapon needs to be capable of multiple roles. ASG has released the ASG SA-58 OSW AEG Proline Metal Airsoft Rifle, fully licensed by DS Arms. The DSA OSW AEG’s full metal construction makes it durable, while its folding skeleton stock reduces weight and makes it more efficient in CQB environments. The ambidextrous mag release located at the front end of the trigger guard gives the ability to quickly reload no matter the firing position. Rightfully called the OSW (Offensive Suppression Weapon), the ASG SA58 AEG includes a 500-round high capacity magazine, meaning reloading frequently will be an issue of the past. To insure accuracy and power, ASG has included a 6.03mm tightbore inner barrel, giving better air seal. Furthermore, the SA58 OSW has an easily accessible hop-up unit, accessed by racking the charging handle back (which is locked by an improved bolt catch). The hop-system allows for increased accuracy at a distance. The 16.5-inch upper rail in addition to the three 5-inch side and under rail segments means you will have more than enough space for your favorite sighting systems, lasers, grenade launchers, and more. This allows you to customize the OSW AEG to your exact specifications.

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 that carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Color: BLACK

Battery Charger Recommendation: Although this fully automatic 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.
