Our take:  What sets the Bolt line of AEGs from other EBB airsoft rifles is the mechanics behind its blowback system.  The Bolt M4 SOPMOD AEG features an innovative Bolt Recoil Shock System (B.R.S.S.) located inside the buffer tube.  The weighted recoil system combined with the blowback action of reciprocating bolt in the receiver, however, delivers responsive recoil highly comparable to other electric recoil electric guns on the market.  If that isn’t enough to pique your interest, the B4 SOPMOD AEG sports Bolt’s upgraded internal components already installed.

A 6.00mm (+/- 0.01) tightbore inner barrel provides improved air seal, yielding increased range, accuracy and muzzle velocity.  The lightweight Bolt piston, made out of rugged aluminum, comes with a full steel tooth set that puts up with the abuse of this high performing rifle.  And a stainless steel gear set significantly improves the durability of the gearbox, including the CNC-machined Bolt spur gear that reacts and functions optimally under high stress.

Also included in this electric recoil AEG is a rubber spring buffer inside the piston that reduces the overall wear of the metal gearbox.  Unlike other electric recoil rifles, the Bolt M4 SOPMOD Airsoft AEG is wired to the rear and is equipped a six-position crane stock.  This makes it easy to house the recommended 11.1V LiPo nunchuck battery (with 20/25C discharge rate).  The Bolt B4 SOPMOD is an upgraded AEG that features responsive recoil, pre-upgraded furniture and well-made internal parts in a single package.

Battery Charger Recommendation:  Airsoft Megastore recommends the use of a universal 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.

The store is amazing. I have found there items that I could not find in other stores which makes it the best. I have made questions and inquires about products and the customer service has responded super fast with accurate answers. All my products have arrived in excellent conditions in spite of other stores. My last product came late because it was rescheduled but that was UPS fault I think. I would like to thank Matthew for his exceptional customer service. Whenever you need help, please try to contact him. My advice, buy in Airsoft Megastore, they have coupons and the widest variety of airsoft products. RandyLoy, USA
I ordered a gun sling a couple weeks ago. Unfortunately, one of the clips broke. After a few email correspondings with a customer service representative named Jun (my emails did not show a last name), AMS sent me a replacement sling for free. I did not even have to send my clip back. AMS is a terrific store and I plan on doing more business with them. They were polite, efficient, and just a pleasure to work with. I would recommend Airsoft Megastore to anyone. mskanwischer, USA
Airsoft Megastore is The Best Airsoft Website Out There (I Think) and i Will Always Be Loyal to AMS and Order Almost All of my Gear From Them. The Customer Service is Also Amazing, Jun my Customer Service Representative Has Helped Me With Anything i Needed Help With, Especially My Order Problem (Had 2 Magazines Missing from Order) and Jun Helped Me With The Problem, and Now The Mags Have Been Shipped To Me. Thank You So Much AMS and Jun. Ethan1214, Saskatchewan, Canada
I love that Airsoft Megastore has videos of most any information you will need to learn and care for your products. I purchased an AEG for my son and in short order, unfortunately, it began grinding after brief use. I emailed for warranty repair with symptoms and with 24 hours (22 to be exact) I received an email explaining possible causes with a video like for tuning the gun. I had the gun working again within 15 minutes, avoiding returning the gun and the mess associated with returns\repairs. Excellence on Sean's part to help out a first time customer of theirs. Highly recommend. bucfanjeff, USA
