How is the BDC calculated? Will the distance on the BDC be off between an 18" barrell and a 24" barrel (velocity often drops 25fps/1in. of barrel)?

I run it on a 24 in bull barrel and the Nikon website (http://spoton.nikonsportoptics.com/spoton/spoton.html#:4) I believe bases the ballistic coefficient on a 24 inch barrel and when I print up some of the bdc chart for my given ammo I'm shooting, it's pretty accurate. I was going to put it originally on my 18" barrel model and was reading that the bdc's would be pretty close. What was recommended was get the bdc print out, and then head to the range and you can see the slight differences on each circle and them you can adjust accordingly. I know that sounds like a pain, but the guy that was going over it, said that each bdc circle would be off say 5 or so yards so say if one would be 200, it would actually be 193 and so on. The bottom line is even with a 24 in barrel, I still confirm the bdc circles on each different round I fire down range. The scope is great and I just bought one for my father in law and he is hooked and a big fan. Hope that helps

Well the BDC on this scope is set for the default m185 Full metal jacket 55gr Nato round. Yes barrel length will make a difference. You can either reload your own ammo and develop a load that works with your barrel to make the proper velocity or you can enter your ammo specs in on Nikons site and it will give you range adjustments for the dots on the BDC600. I recommend loading your own to stay true to the distant marks as much as possible. I load Hornady 55gr and ran a chronograph shooting different loads till I found the right mix. I have 20" 1/7 BCM match for an upper. Also get the mount for this scope makes mounting a breeze. Well the BDC on this scope is set for the default m185 Full metal jacket 55gr Nato round.

The drop in the reticle is based off the trajectory of a 55 grain polymer tipped bullet. They list the muzzle velocity they based their ballistics on. Check your muzzle velocity and adjust accordingly.

You have to get the apex ready barrel bc its designed to hold and rotate the tip or you can buy the barrel and apex tip for 40 to 50 on amazon. Remember the velocity at the field is set around 280. That being said the length of the barrel does not increase accuracy it's the quality of the barrel. They made 18 inch barrels BC people like to play milsim (military simulation) games. With a milsim gun they have shrouds that will not fit a 14 inch so they make 18 inch. A lot of people say 12 to 14 inch barrels are the best bc they have less drag. I got a 12 inch lapco apex ready barrel for my electric marker. I would only go 18 inch if you have kits on your gun that require a barrel longer then 14 inches

My best guess is about 100 feet with good accuracy. The BB will travel pretty far, but believe it loses velocity after about 100 feet.

For the BDC reticles to work properly, the scope needs to be zeroed at 100 yds. That being said, experimentation on your own at different distances may provide other workable solutions.

officers and defender model have a shorter butt than a full size, barrel has nothing to do with it. measure between mounting screws ,if they're 3 1/8" apart it full size . if its 2 11/16 its for a compact.

James...think of it as a cone emitting from the barrel of the temp. gun....the farther away your target is the wider the cone gets...thus the larger area that the temp is taken. If you are taking the temp of a wall 10 feet away, no problem because the wall will probably all be the same temp...however if you were taking the temp. of a small area on that wall...you would want to move closer to get an accurate reading...the cone to distance ratio is 12:1 if that is a help to you. A target 8 feet away will measure temp. from a circle of about 12 inches...and I have found the target distance to read area stays consistent throughout. Hope this helps...

I'm not sure, however, I get phenomenal results spraying at 25 cfm with very little product used. The gun don't seem to like the higher pressure as my previous spray gun did.

445-450 with .2sbut it seems like all of us are getting different fps reading here so because i don't believe they are putting widely different springs in each gun I am forced to believe that its the chonos that are wrong. Ill go get mine calibrated and be back with the results

I believe they make a separate model for the newer tapered barrels, mine is on the 196 with straight barrel profile, and helps accuracy greatly, also looks pretty good too.

I think it will depend on how large a barrel you are using. your pressure will be determined by weight of the water in the barrel.

We'll Develin, Nikon doesn't make a bad optic product (Even though I use Canon glass for my camera). So no matter which one you choose, I'm sure you will be happy with your decision. As far as the BDC feature, I understand why you would question the wisdom of having it on a .22. My thinking is that not having BDC is not a deal breaker but having it for only $10 more is not a bad thing either. You probably won't use it a lot but having it might be an advantage from time to time. Good luck and good shooting.

Haven't used a cyclone barrel before. The cyclone probably boasts that it can impart rifling on the paintball, which, may or may not be true. The 22" Rap 4 works great for me. The extra accuracy outweighs the burden of having a 2 foot of barrel to contend with in the woods. 1st Shot rounds work awesome in this barrel as well. I highly recommend the Rap4 for price and performance!

That is the hole that the barrel goes thru, the two sizes, 15/16 is slightly smaller than the 1 1/4 and thus tighter to the barrel without touching it. It gives a nice finished touch to it. Most bull type barrels need the larger while the standard .750 barrel will take the 15/16, hope this helps

Fps is feet per second and 20g bbs is the size of your bbs. I've also used 6mm bbs.

I have mini14 bought this for it ,i have the 18 inch. Ordered the 6 inch., looks great will help the barrel to be stabalize and will reduce heat from the barrel , highly recommented ,no regrets... will look like m14

Approximately .660. I have one on a Tikka and the barrel measures @.625. Just make sure it is even all the way around. I hope this helps.
