Page 3 of 4 - Air Venturi Ported Muzzlebrake, .579" Reviews

It complements the barrels after exterior sites are removed.

It's a little pricey for for spun aluminum with black anodize. Set screws need to be larger and cup pointed.

I did see a slight increase in velocity (7-15 fps) on a Crosman Model 700 and 99, more so on the Crosman 700 (I did have to cut a slot for the front site and it turned out very nice since the aluminum was very workable) With the slot cut for the front site it is interchangeable between a Crosman 700, 400 or 99. I did notice a slight sound decrease As others have noticed it does look cool

I tried every standard and metic allen wrench I owned and couldn't get one to fit exactly. It would be nice if they supplied the allen wrench. The finish on mine was spotty and rough in spots (round dimples) so I ended up smoothing it out and of course that removed the anodizing, so I just painted it flat black and it did look much better.

Looks great, quality workmanship in the machining, BUT

made of a harder grade of aluminum, very easy to scratch and nick. Black coating is too thin and easily scratched and scuffed. Lock down set screws appear to be metric, may be had to replace if lost.

Looks really good mounted and as a base to start from. I too had to modify diameter to fit my gun and allow for brass shim stock to protect the barrel from the set screws. I choose to re-tap screws to 8/32 and add two more at 90 degrees to provide extra hold for laser pointer mounting on the underside. Brake has sufficient material to modify as desired.

This is a great dress up part. I've used them on several guns,including a co2 rifle.I have a lathe,so making them fit almost any gun is easy for me,MUCH easier and nicer than machining a break from scratch.

Nothing,great as is.

Looks great, lightweight (aluminum), nice finish.

More availability for other barrel diameters.

This looks great on my cut-down B3-4. Fits perfectly on the barrel.
Great price for a nice piece of trim.
Does NOT fit on QB-78 family with 15mm barrels, Will fit loosely on 14mm barrels.

The Beeman Ported Muzzlebrake fit my TF-89 like it was made for it. Quality of manufacture, fit, and finish were all good for the $22.00 price paid. Don't know for sure if the porting really reduces muzzle rise but it does look good on my rifle.

Nothing...This muzzlebreak looks better then factory , porting gives it a non slip texture.

Fits Beeman RS series, TF-89 and Titan.

Fits my Beeman RS series barrels like a glove, looks good, provides additional leverage for cocking

Either use larger set screws or provide a spare - I stripped the hex head out tightening one down.

I pulled the (glued on) plastic front sight off of my Beeman RS series barrels and replaced them with these muzzle breaks. They fit perfectly, the front screw sets in just a little deeper because the barrel is turned down a little under the old sight but there is plenty of contact area for a secure fit. I can't say if these make me shoot any better but they sure look better than the cheesy plastic sight the comes on the Beeman barrels.

Well made and excellent quality!

Can't think of anything that could be better

Clean nice fit and lightweight, made cocking easier.

None

This makes your gun look good!

It actually does control the muzzle allot more than I thought it would! It has controlled my shooting 100%. It makes a killer finishing touch to my set up.

Not a thing. Very satisfied!!

This product is cheep and will improve anyones shot!
