SRC CompSpec
SRC's CompSpec series of full metal gearbox, high-performance AEGs are designed for the value-minded Airsoft enthusiast who wants both quality and performance at prices that were previously unheard of.  For all too long, Airsoft Megastore has heard customers say time and time again that they'd love to get their hands on a SRC AEG with a full metal gearbox, but "ONLY IF" pricing was better.  Well, we've definitely taken these comments into direct consideration in carrying the new CompSpec line of AEGs, designed to take the AEG market by storm even in a time of uncertainty in the Airsoft market.

Simply put, CompSpec, or Competion-Spec SRC models are durable AEG models with high performance full metal gearboxes that are strategically tuned to deliver upwards of 350-380 FPS of power and stay BELOW most indoor/outdoor Airsoft field limits and hence, are "field-legal" without modifications.  Oh, and in case you haven't already noticed from their AMAZING pricing points, CompSpec AEGs have to all of the above while delivering UNBEATABLE VALUE.

As the #1 fastest-growing Airsoft retailer in the nation, Airsoft Megastore has made a huge commitment to SRC in order to secure top-tiered volume discounts on the entire CompSpec line of AEGs.  We are proud to carry the entire SRC CompSpec line of high-performance AEGs at the lowest prices on the market, bar none.

Our take:  The SRC CompSpec M4A1 Carbine, the quintessential primary weapon, is a realistic, durable, and full size AEG rifle from SRC that features a full metal gearbox, a high-performance cylinder crafted from aluminum, and a high torque motor.  The rear stock, in typical M4 fashion, is retractable/adjustable (4-position) for comfort, and the carry handle is removable (revealing a receiver-top rail on which you can mount optics).

One of the most unique features about the SRC M4A1 Carbine is its receiver.  Unlike older ABS receivers such as receivers found on Tokyo Marui AEGs, the SRC M4A1 sports a fiber polymer reinforced ABS receiver, which means a higher level of build quality and more significantly, DURABILITY, all-around.  The receiver features a higher density than most standard receivers, and as a result, is more durable and less prone to cracking or breaking due to an inadvertent drop or collision.

As always, the M4's retractable/adjustable rear stock maximizes comfort and versatility on the field.  With the rear stock extended, take on outdoor games in full-force fury.  With the rear stock retracted, CQB matches are conquered with ease, as you glide through narrow doorways and around corners with the agility only your compacted rifle can provide you.

Unbeatable Value:  In an Airsoft market full of rising prices, it is extremely refreshing to find a FULL METAL GEARBOX, highly durable and realistic AEG rifle for such a bargain, let alone one from SRC, one of the most reputable and well-regarded Airsoft manufacturers to come out of Taiwan.  In our opinion, the entire CompSpec line of AEGs was built to appease Airsofters who wanted to get an AFFORDABLE SRC.

Technical Specifications:
Operation:  Electric automatic; safe mode/semi auto mode/full auto mode
Rate of Fire: 750-850 rounds per minute
Muzzle Velocity:  340-380 FPS with 0.20g seamless BBs
Hop-up: Adjustable/integrated
Gearbox: Full metal
Receiver/body: Fiber polymer reinforced ABS
Internals:  High strength polymer bushings w/ aluminum cylinder and reinforced gear-set
Barrel: Metallic composite
Motor: SRC High-Torque
Battery compatibility: 8.4v mini-type battery
Weight: 6.5 pounds (extremely realistic)

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.

Package includes: Rifle, instruction manual, 300-round high capacity magazine

Note:  Battery and charger are NOT included, as is the case with most SRC-manufactured AEGs.  For the best value and performance, we recommend getting a 8.4v mini battery and a universal smart charger.

Battery Charger Recommendation:  This AEG DOES NOT come with a battery or charger.  Although this fully automatic airsoft rifle can use 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.

really nice

"this gun for 107 dollars is completely worth it, i have been playing airsoft for a long time and i own guns such as a cyma m14 socom, and a KWA sr10 (custom) and a KWA KP45 and i got this gun as a gun to put many magpul parts onto... worth it Pros: Accurate CHEAP Rof is decent range is pretty good for a stock gun body is really tough Cons: ROF is decent sort of hard to get the battery in especially compare to a KWA Otherwise if your a noob looking for a gun, or a pro looking for a cheap project gun get this"

"If you really want this gun, get a better battery and have a friend help you with a internal spring upgrade. get something a little more expensive. its worth it because a gun like this may last 5 wars before becoming dysfunctional."

prty good

"i got this gun a few months ago and it was very accurate. .25's are a little to heavy for it so i recommend using .20's. the only thing that didn't satisfy me is that the D-boys 110 rd mags dont feed well, and they jam the gun. decent rof (rate of fire) pros: accurate metal gearbox good fps prty durable cons: the stock and the handguard were a little tiny bit wobbly the battery was hard to put in for some reason, in the middle of a game it just started making an unending sound like a power drill and i havnt gotten it fixed yet. i think i may have accidently put in a bad bb in the mag, but i took it apart and couldn't find one "

4 SRC Airsoft M4A1 Carbine Full Metal Gearbox AEG Rifle - SR4 Series *****

"i just got this gun today. first of all, the stock is TEENSY. the stock part itself is about 4" tall. it is 3 position not 4, but i really dont mind it. the battery fits in nicely, and the fire selecting switch is in a great place. the hop up is pretty good, the gun weighs perfect. the forearm plastic is very very flimsy and cheap but the rest of the gun's ABS plastic is very durable. the rate of fire is average and the velocity is a bit slow for field use but it'll work fine. over all, this is a pretty decent gun. if ur like me and wanna have a reliable gun that'll perform well but you dont wanna have to spend a fortune, get this gun."

Okay for a little while...

"I got this gun a few years back for Christmas, and when I first opened it and went out to play, it was great. Then, 4 months later, things started breaking and the FPS dropped to about 290 with .20s. Overall, alright if you're just starting out, but don't expect to have it too long"

Best in Class Customer Service

Same Day Will Call Pickup

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
Everything worked great, shipping was super fast. I am very pleased and won't hesitate to order through airsoft megastore again. rob_riley, USA
