Ammunition Capacity: 300+ round magazine.

FPS: 360+.

Trigger Pull: The trigger pull on the BOLT Airsoft M16A4 is fairly short and light as it is essentially just an on off switch for the internal electronic components. You can shoot this gun very quickly in semi auto mode, and of course in full auto when full auto position is selected. As is with all AEG rifles there is a bit of a delay while the spring is retracted and released, this is not as noticeable in full auto mode and also when using higher voltage 11.1 volt batteries.

Accuracy: I tested the BOLT M16A4 BRSS Airsoft rifle first on my Chronograph to see what kind of real world fps I would get from it using .20 gram Airsfot BB's. The BOLT M16A4 produced consistent 350 fps shots which is perfect for indoor or outdoor Airsoft events. I then stepped back roughly 30 feet and place 10 rounds on my paper target using a semi rested position and was able to get a nice tight 2 inch grouping. When switching up to full auto mode the grouping pretty much stayed exactly the same, right in that 2 inch pocket.

Build Quality: The Bolt M16A4 AEG Blowback Airsoft Rifle is very well made with a full Metal upper and lower receiver, along with metal and polymer parts exactly where they would be on the real steel version of an actual M16 or AR styled riffle. The only rubber or nylon components are the stock and the grips and perhaps some internal parts. I really could not find anything to complain about other than making sure to use the right sized ammo as the barrel is a true 6mm barrel and so when using actual 6mm BB's they can get jammed up. I had great results when I used 5.95mm Airsfot BB's.

Realism: As with many Airsoft guns, there is great attention to realism and the Bolt Airsoft BRSS M16A4 AEG is another great example of an Airsoft rifle based on the Colt M4 platform. It is an AEG but because of the Heavy BRSS (Bolt Recoil Shock System) you get a very nice compromise between a conventional AEG and a GBB (Gas Blow Back Airsoft) gun. In other words, like a standard AEG I get that endless stream of consistent BB's flying down range on target but unlike a true Gas Blow Back Airsoft gun, I don't get that drop off in power and limitation to about 30 usable rounds per magazine. What I do get similar to a GBB is that recoil action that helps make the shooting experience so much more believable! Even the sound from the Bolt M16A4 is much snapper than a standard AEG and more like a GBB. I also like the fact that the charging handle and forward assist work similarly to a real AR and also the dust cover cleverly exposes the bolt and internal hop-up for easy adjustment along with the bolt cycling just like a GBB rifle would cycle which is similar to a real steel AR.


  • AEG Performance with GBB like Recoil.
  • Very high quality materials and workmanship throughout.
  • Lots of forward rails to place accessories on and just looks cool in general.
  • The fixed classic M16 stock is very comfortable and grows on you over time.
  • Can shorten the gun by removing the barrel extension if you like.
  • Can use 11.1V Li-Po or 9.6V Ni-mh or Ni-Cd batteries.
  • Fully Adjustable Hop-up.
  • Semi and Full Auto.


  • BRSS system will drain the batteries faster than a standard AEG.
  • Can not switch out the stock as the BRSS system extends back into it.
  • Need to use undersized 6mm Airsoft BB’s because of the tight barrel.


The BOLT M16A4 AEG Blowback Airsoft Rifle with BRSS Recoil is a great compromise for the avid Airsofter looking for a practical skirmish weapon, but also craving the realistic experience of having blowback with recoil similar to a Gas Blow Back systems. I really like this concept and find it great fun to shoot even if its just for plinking in the yard. The overall quality is very excellent and you just have to love the AR platform it's based on. If you're into customizing you can mix and match many external and internal parts with other existing Airsoft mechanical parts and I would imagine real steel accessories. It's great to be able to use an Airsoft rifle in virtually any weather condition and still get that Gas Blowback Feel but with AEG performance and consistency.
