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 Bolt B4 CQB-R M4 Full Metal Airsoft AEG Rifle - BLACK *****
Excellent CQB/Mid range rifle

"I received this in the Memorial Day Mystery Box. At first I was disappointed to have received an M4, but I was pleasantly surprised. The rate of fire is solid, accuracy nice, and consistency excellent. The somewhat light weight is fantastic for close range and mid range, but don't be fooled: this weapon is well constructed. Although I wish there were some attachment rails, the BRSS Electric Recoil system more than makes up for it. I feel as though I'm firing a CO2 or Gas rifle. Overall Impressions at a glance: Pros: Solid Build Consistency Accuracy Decent Range Potential for Modification Cheap Price (for me, it cost $125 due to the Mystery Box) Cons: Lack of Frontal Modification Relatively High MSRP Price ($225) ///MUST/// Purchase Battery Separately 9.5/10 for the Rifle 6/10 for MSRP Price with lack of Battery 11/10 for my fortunes in receiving this instead of a beginner's M4 Final Score: 8.9/10"

4 Bolt B4 CQB-R M4 Full Metal Airsoft AEG Rifle - BLACK *****
Great little CQB-R just keep in mind this does NOT have the recoil system

"I picked one of these up when they were on sale in the past, originally thinking this had the same BRSS system as what is in my Bolt B4 MK18, however it does *NOT* so anyone considering this should keep that in mind. With those (minor) cons aside this is a very solid CQB-R that I've been using on and off for months and it has never let me down. It shot a very CQB-friendly 330FPS out of the box and has continued to be extremely consistent. It has the same rotary hop-up of the higher-end Bolt models, has nicer externals than most guns in this price range and continues to impress. I put a MagPul MOE handguard and vertical grip on mine and they fit without any issues."

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
Best Site for Airsofting Gear and Guns
