Question: I bought my first .625 about 20 years ago but it seriously rusted!  Is this aluminum or stainless steel?  Can't find where it says what it's made of?After reconsidering the events, it was more like 35 years ago when I got the first one. I actually still have it because it's still a good walking stick and CLUB.
Document: At first I thought using it for a walking stick would bend it, now I take it everywhere. I even bought on for my friend!
What a wonderful piece of equipment to have around... works as a walking stick although I am not sure Security at the airport will find it amusing. And this shoots perfectly. My Son and I have had a blast shooting this during practice and are getting pretty accurate and can't wait to enjoy a little hunting with it.
And finally as far as the &#34;walking stick&#34; feature of this product goes, Not so much. The plastic cap they give you to cover the end of the gun fits on so snug that it don't want to come off very easily if you are in 30F or less. I won't buy it again. Cold steel is a decent company but their Chinese made products are getting worse.
This is a great item. I bought one for myself and 2 for friends of mine and we all agree. It is very durable and came with a variety of darts to see what you like or don't like to shoot.I would recommend this item to anyone
this is absolutely the best blow gun I have ever owned, no doubt about it, it has power, reliability, and is a good walking stick
Bought this for my boyfriend as a Christmas gift. He loves it. Shoots every box in the house he can find. A little scared he might shoot me with it! only one dart was broken and won't go through the gun, all others worked fine.
Let me start off by saying this is a terrific blowgun, I can keep a 6 inch grouping at 15 meters, and effective up to 20. The mouthpiece doubles nicely as a handle, single piece of aluminum that seems durable enough. I have had this blowgun for 2 weeks and have killed 3 squirrel with it so far, one at 20 meters straight into the shoulder.
The Cold Steel 4foot .625 Big Bore is a worthy hunting weapon for its caliber, suited for small game. The metal is heavy duty, extremely rigid and strong enough to use as a walking staff. It shipped with a selection of darts from stun darts, to target darts to mini broad heads. I am well pleased with the purchase all around.
WOW!!! L O V E THIS THING!!!! I can blow a dart about to about 100 ft high and well over 200 ft in travel distance in one shot and the dart actually sinks into the asphalt road after clearing my fence. I couldn't believe how well it performs!!! Stick with the big bore blowguns and don't get the smaller bore ones. My kids love it too.
