Avengers CNC Aluminum Free Float Rail System for M4 Series Airsoft AEG Rifles (Length: 7")

"This is for the 12.5 version, though I believe the rails are all made the same way.

First impression is these are solid, well made, and well put together.

Mine fit nicely on a very old Echo 1 gun I turned into a more modern DMR build.

No wobble or wiggle. Fairly straightforward to do. The barrel collar and barrel nut screw onto the gun first. The barrel collar sits between the barrel nut (the part you screw down) and the receiver. The pins ensure the rail doesn't rotate once it's tightened down.

The only issue I ran into is the pins sit relatively loose between the nut and the rail, allowing them to rattle just slightly. Not a big issue, just a minor nitpick.

Overall, exactly what I needed and expected.

"I swapped a 7” rail for this one with a 10.5” barrel and am absolutely in love with it. The rail is very sturdy and solid. There’s plenty of rail space for attachments and accessories.

"This rail fits well on my G&P and looks awesome!

"Pretty well made. Fit my M4 AEG. Was a breeze to install, you can find installation process on youtube.

Pros:
Looks great
Quality
Installation was not too difficult

Cons:
Nothing really

"I really love this rail system it cheap, reliable and really strong aluminum. I bought this rail system for my m16 build and it fit the build perfectly. I highly recommend this rail system to anybody, and it is kind of hard to front wired but you can do it, and the paint is not the best so I do recommend buying rail covers as well.

"Very happy with the quality of the piece. Arrived in about 10 days, so not bad for shipping time. It seems to be made of a high quality aluminum and is very strong. Once mounted to the rifle, it is very sturdy and doesn't wiggle or anything. It was also very easy to put on. I'd recommend this.

"will this fit "The Perfect Holiday Gift Package" Avengers BioHazard M4 Lipo Ready Airsoft AEG Rifle because im getting this with the gun and i want to get it right first try

"Bought this rail about a month ago and it was the best 50 buck i ever spent on my gun. Fit right on and was very tight. I had to put a screw driver through the delta ring into the hole for the gas block in the upper receiver to get it really tight. This also allowed me to have it lined up parallel. In the picture is shows this bolted on little piece behind the delta ring. That locks on to the upper receiver in the front so even if the delta ring is screwed on or is loose it doesn't move. It looks awesome and is the perfect length.

MY Only cons are-
It didn't come with directions and took me a while to get it just right.

The inner diameter is 1 and 1/8 a little bigger than that but still small enough that i couldn't make my suppressor look integrated. I just made a dense plastic suppressor and used a lathe to machine it down to the right size.

"I have the King Arms version of this exact hand guard (has licensed LaRue Tactical markings and same "live free or die." marking), and it is without a doubt my favorite hand guard on the market. It's very slim-line and mounts to any standard M4 AEG receiver with ease. If using G&P it will require the Madbull DRM Tool to fit properly. No strange pins to insert to hold in place and has a nice locking ring to keep it stable. I recommend this rail to anyone using a standard barrel without integrated suppressor.

PROS:
- Looks and feels amazing with slim-line design.
- Installs with ease.
- Fits perfect with most gas tubes and gas blocks.
- Looks ultra awesome with Madbull Noveske barrels.

CONS:
- Picture shows locking ring on bottom when it should be on top ;)
- Will not fit most silencer/suppressors internally (only a 31mm opening).

TO SUM IT UP:
- GET THIS HANDGUARD!!!

"I bought these rails about 2 months ago for my DMR setup. These rails are super lite compared to others of the same length. They use a common thread size , they fit my G&P upper as well as a friends KWA mod1 aeg.. These also fitted a real ar15 upper . Theses rails are supper solid imo. Now to the pro and cons

Pro
-light weight
-durable
-really easy to install even if you know nothing
-great price
-

Cons
-not made to be use for front wired guns (Can be done but really hard)
-Rails are sharp (I do suggest rail covers)

"I give it 5 star just for the price the rail it self deserve 10 star very nicely build very easy to install if you have the barrel shims I also like the way it secures to the upper receiver 2 Allen key from the back no Wobble at all I got the 12 inch Version

Pros
Good Price
Well constructed
Light wight
Rail have number makerings
Again yeah mention price lol

Con
None so far

"This is a cautionary review of the Avengers 12" CNC FF RIS unit. I have a Classic Army M15A4 AEG (Spartan Version) bought from Evike and purchased this very rail to install. The installation looks pretty simple if you can get your delta ring off, however the problem is: this rail DOES NOT FIT the AEG I have.

The threading on the outside of the upper receiver around the outer barrel that secures the delta ring for the original hand guards is where the FF RIS screws onto and secures from. The threading of the rail's barrel nut (where it screws onto the gun, it doesn't clamp in like regular quad rails or normal hand guards) is incompatible with the Classic Army Spartan Version M15 series, and I bet that goes for the 9 and 10" variations of this rail as well. I am still looking for a fix so I don't have to spend MORE money on a rail system after this buy.

My advice: do some research and check out the forums before buying, and make sure that your gun is up to spec for the rail that you're eying.

"Purchased this hand guard while back and I finally got around to installing it on my RM4. Installation was fairly simple as this is a replica of the Larue Tactical hand guard. The hand guard both feels and looks good and honestly I would give it a 5 star rating if the QD sockets were sized correctly. They are shallow and will not properly hold a sling swivel. I'll give this rail a 3 (I would rather a 2.5) as the build quality is good everywhere else but I will be replacing this as soon as I get around to finding another good rail with a similarly placed QD socket.

Pros:
Good price
Looks good
Sturdy

Cons:
-Didn't come with instructions (for someone unfamiliar with this type of hand guard installation would be tricky)
-The QD sockets (at least on my hand guard ) are shallow and do not function

Conclusion:
Could have been an awesome rail but it does have a major flaw in the QD sockets

"I got this rail a while ago for my M4. It isn't the best rail on the market but if you are on a tight budget then this is an acceptable rail for the price. The rails themselves aren't actually 20mm but more like 18 or 19mm. So that is something to be aware of. The paint also scratches easily revealing a shiny under coat. Overall you get what you pay for. I would look at other rails if in your budget.

Pros:
Solid
Easy install

Cons:
Paint scratches easy
Not 20mm

"Installing this rail system was the most frustrating thing I've ever done. It literally took me three hours of blood, sweat, and tears to put this thing on.... and its still not straight. However, I cannot complain because of the price. I don't believe that there is a cheaper RIS on the market as of right now.

Pros:
Cheap
Looks good

Cons:
Hard to install
Didn't come with instructions
Doesn't fit on the gun straight (Might with a lot more time and work)

Overall, it wasn't a bad purchase. It still works, and it is pretty solid.
