My first impressions with the Bolt M16A4 AEG Blowback Airsoft Rifle where not so good as it was miss feeding and miss firing terribly for me. A quick communication with BOLT Airsoft and I was informed that perhpas my BB choice was the wrong one. The Bolt M16A4 AEG Blowback Airsoft Rifle has a true 6mm barrel so it is a tight fit with BB's that are 6mm since many can actually be a bit larger making them get stuck in the breach area.

BOLT Airsoft suggested I switch my Airsfot BB choice to a slightly under sized 6mm Airsfot BB so I tried some of my 5.95mm Airsoft BB's and all I can say is it was like shooting a different gun. Not only did it feed and shoot perfectly, but the Bolt M16A4 AEG Blowback Airsoft Rifle with Heavy BRSS Recoil also became instantly more accurate for me. The moral of this story is always make sure to use the right ammo in your gun :)

So getting back to my Field Test Shooting Review for the Bolt M16A4 AEG Blowback Airsoft Rifle with BRSS Heavy Recoil... In this video Field Test Review I shoot several rounds through my Chronograph to test out the fps velocity of the Bolt M16A4 AEG Blowback Airsoft Rifle. Which by the way came in around the mid 300's. I also step back 30 feet and shoot some semi auto rounds into a paper target to see how accurate the Bolt M16A4 AEG Blowback Airsoft Rifle is. Since the Bolt M16A4 AEG Blowback Airsoft Rifle is a semi and full auto AEG Airsoft rifle, I also had to replicate my accuracy in full auto to see if my groupings would stay consistent even at a high rate of fire. I was very impressed with the accuracy in both semi and full auto, form 30 feet out you will get within 2 inches all day long.

It is fair to note that I was using 11.1 volt Li-po batteries with .20 gram BB's for the entire testing so this did effect my motor speed giving me quicker trigger response and faster full auto rate of fire. I would suggest using a high capacity battery setup since the BRSS Heavy Recoil does use up some additional battery power but boy is it worth it. The BRSS Recoil is not going to be as heavy as a true gas blowback system but it is close and does give you a nice shoulder tap but with the benefit of high capacity AEG magazines and consistent AEG performance.

In a nutshell, if you want the dependability, consistency and none stop shooting performance of an AEG Airsoft AM16 but with the blowback action of a gas system then make sure to give the Bolt M16A4 AEG Blowback Airsoft Rifle with BRSS Heavy Recoil a good look into.

A while back, BOLT was kind enough to send me one of their B.R.S.S. Recoil AEG Airsoft Rifles for review, make sure to watch my full review of the BOLT B4A1 BRSS Recoil Blowback AEG Airsoft Rifle.

Well again BOLT came through and sent me their latest offering, the BOLT AEG M16A4 Blowback Airsoft Rifle with B.R.S.S. Heavy Recoil system. B.R.S.S. stands for BOLT Recoil Shock System. The new BOLT Heavy Recoil system has a fixed stock which houses the improved recoil unit giving a more direct and solid recoil effect to the users shoulder. The BOLT M16A4 is a long length AEG Blowback Airsoft Rifle also suitable for snipers.

Here are some of the specifications:

• Blowback B.R.R.S Heavy

• Adjustable Hop-up

• Semi & Full Auto

• Standard AR 70 & 300 round magazines

• 312 fps & 393 fps versions

• Aluminum, ABS, Nylon & Glass Fiber and Steel construction.

• 7.4V & 11.1V (Li-Po) or 9.6V (Ni-mh / Ni-Cd)

• 7.7 pounds (3500 grams)

• 43 inches long (1100mm)

• Comes in Black / Tan

In this YouTube Preview video for the BOLT M16A4 AEG Blowback Airsoft Rifle I show you around the gun a bit and do a quick shooting test. Unfortunately I was using 6mm Airsoft BB's which I later found out where a bit to large in diameter since the BOLT M16A4 AEG Blowback Airsoft Rifle has a true 6mm barrel. After the video when I received this information from BOLT I switched to 5.95mm Airsoft BB's and the BOLT M16A4 AEG Blowback Airsoft Rifle worked perfectly for me :)

Stay tuned for my Full Table Top and Field Test Shooting videos for the BOLT M16A4 AEG Blowback Airsoft Rifle:

Type: Airsoft AEG.

Manufacturer: Bolt Airsoft.

Model:B4A1 with BRRS (Bolt Recoil Shock System).

Materials: Metal & Nylon.

Weight: 6 pounds.

Barrel: 15 inches, metal.

Propulsion: AEG with BRSS

Action: Semi/full auto, single action.

Ammunition Type: 6mm Plastic Airsoft BB (recommended .20 gram plus).

Ammunition Capacity: 300+ round magazine.

FPS: 366-400.

Trigger Pull: The trigger pull on the Bolt Airsoft B4A1 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.

Accuracy: I tested the B4A1 Airsoft rifle by putting around 10 rounds into a target from 30 feet with .36 gram Airsoft 6mm BB's while using a semi rested position (sand bag in the front - standing in the rear). I used a non-magnified red dot scope for this test rather than using the built in iron sights. I got very good result in semi auto and even with the recoil making my sights jump around a bit in full auto still stayed well centered on target and got about a 1.5 inch group in both semi and full auto. My chronograph testing with lighter .20 gram BB's resulted in a 421 fps 5 shot average.

Build Quality: The Bolt Airsoft B4A1 Metal AEG Carbine 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 Colt M4. The only plastic or nylon components are the stocks and the grips and perhaps some internal parts. I found the adjustable stock and magazine tolerance to be tighter than my King Arms M4A1 I previously reviewed which showed the Bolt B4A1 had a bit higher quality in the workmanship, for the most part the fit and finish was very good!

Realism: As with many Airsoft guns, there is great attention to realism and the Bolt Airsoft BRSS B4A1 Carbine is another great example of an Airsoft Carbine based on the Colt M4 platform. It is an AEG but because of the 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 B4A1 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 M4 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 M4.

Purchased From: The Replica Airguns Store.

Pros:

• Great attention to detail with lots of working parts.

• All Metal upper and lower receiver, lots of metal parts throughout.

• Realistic Blowback Recoil system (BRSS) for a very believable shooting experience!

Cons:

• May not get off as many shots per battery charge as a traditional AEG because of the Bolt Recoil Shock System.

• Does not come with battery or charger but most higher end AEG's also do not.

• Not yet readily available in Canada, maybe we can change that :)

Comments:

The Bolt Airsoft B4A1 Blowback Airsoft Carbine 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 which up until now was really only provided by 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 good and you just have to love the M4 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. I like mine as is with my addition of a riser and Red Dot and if I every get a chance to get out for a skirmish this will be my weapon of choice for sure!
