FX Impact arrow barrel.

Jump to latest Follow Reply
Sorry I did not provide the OD of the Impact arrow. But I'm fairly certain that the ID of the arrow barrel was much greater than a standard .30 barrel (which has the SmoothTwist choke at the muzzle). Not only is the arrow thicker, but the plug & o-ring make it even wider. No word from FX whether they will actually put it into production.

Michael Does the tip of the arrow recess into the tube?
If not put a fixed blade broad head on. Find a BIG target to shoot at
and see what happens. Also try longer yardage with field tip. Fletching
does indeed help correct paradox but it also putts a spin on the shaft would be interesting
to see the lack of at long distance. Just a thought have fun!

I shoot bows and crossbows for 40 years.
I am 100% sure that shooting an arrow with broad head without fletching on the arrow will not be accurate.
The broad head will drive the arrow and this is not a good concept.
A crossbow arrow is extremely stiff and mine arrows fletching are all set the same aligned with the stiffest side of each arrow. So the archer paradox is quite invisible and not to consider with crossbow arrows (bolts)
Having fletching on a crossbow mean that the fletching will drive the arrow, and not the broad head.
Plus, each arrow must be inserted the same way, meaning the stiffest arrow side in the same position inside the barrel.
With a arrow with a practice head can do the job that way but no way with a broad head.
The FX MKII Verminator with the arrow tube is a better concept because you can have fletching on your arrows.
FX must do the same for the Impact.

When you look at a bow the force is driving the arrow from the rear, watch a bow in slow motion the arrow flexes along the shaft, the vanes help stabilize the whip quicker. The arrow barrel is driving the arrow from the inside at the front in slow motion you will see very little shaft flex, on a cross bow the bolts need to be extremely stiff due to the heavy short shot cycle, the shaft has lots of force on it 150 lb draw weights and up over about 12 inches of string travel.. broadheads should not be an issue at all.

As a crossbow I use a Scorpyd Ventilator Extreme 175 pounds that shoot 440 fps 20 inches arrow 400 grains weight.
The Ventilator have a 19 inches power stroke and it is the fastest crossbow on the market.
I have done super slow motion videos shooting and there is no flex at all on the arrows.
The Impact barrel design and engineering is totally different than the Verminator.
With the Verminator arrow barrel is a tube barrel and you insert the arrow over it. So the arrow is driven from inside and at the front.
The Impact arrow barrel is another concept. The arrow must have a special designed plug at the back and the arrow is inserted inside the barrel without vaines.
With broad head the Impact arrow will be driven from behind because of the arrow plug behind.
I can guarantee you there will be an accurate issue using broad heads and I will prove it to you when I got one here and video it.

The bolts on the crossbow are stiff that is why you don't see the flex. I guarantee on super slow motion videos you could see flex. Ever watch a rifle or pistol in slow mo....you can see frame Barrel etc flexing. The Impact looks similar just looks like it uses a mechanical seal at the base. Still looks like hollow shaft. I have not seen a good picture of one. 
They don't interest me at all, I shoot 3d archery and also have a couple crossbows.
If the Impact has a closed area at the back and they are pushing it from the back I agree crappy design. I wish I could find the article with the paintball gun shooting the arrows would have been in the mid 80's around the same time a guy was using 22 blanks in a rim fire to shoot them and also the pellet barrel for the bow. I still have one of those somewhere. I laughed when they said the arrow barrel was original. They did it with spear guns way back.

"AZBOBCAT"Doesn't FX have the patent on air powered arrow guns? How is the benjamin air bow different? Seems like I saw someone back in the 80's with a air powered arrow shooter.

Not sure what patents FX has but air powered arrow guns were around long before FX started trading.

Patents are usually for new designs and not always for complete products. They might have a patent on a specific feature of their arrow barrel that is different to all the other pneumatic arrow guns. If that were the case, it wouldn't stop others making an air arrow gun, they just wouldn't be able to copy the design of that component in the countries it was patented. 

Should be easy to look up. Patents kinda have to be public info.

Hi Michael,

I guess you are using crossman airbow arrows...?
