I have compiled this as an FAQ that should answer all of the questions on the BKO. Instead of having to go through 9pages of useless crap like that other "FAQ", I think this would be better. Correct me if Im wrong! (Please do not post any questions here, otherwise it will just end up like the other "faq"...I will update it with some more info asap.) Compliments are welcome!...
Who is the BKO made by, and what is the company's homepage?
The BKO is made by ICD (Indian Creek Designs). There website is http://www.icdpaintball.com
What does BKO stand for?
So far the unofficial say is that BKO satnds for "Bushmaster Knock-Off", but that is still unconfirmed by ICD.
Where can I buy a BKO?
The best places to buy the BKO are from places like paintballgear.com, rockymountainsport.com, 888paintball.com, countypaintball.com, or if you dont mind paying a little extra cash for less of a wait, directly from ICD.
What are the advantages of the BKO compared to other electro guns in its price range?
The BKO is so far the only "true" electro pneumatic gun in its price range. As ICD says "It is not another useless sear-tripper".
What types of upgrades do I NEED to buy for my BKO?
There are not really any upgrades that are a true necesity, but the stock barrel is definately not the highest of quality. Most people suggest buying a drop forward, cheap/nice barrel, and a new regulator for the BKO.
I have heard that there are many different versions of the BKO, is this true?
Actually no, this is a generic term that was applied to variations in the marker since its inception. There are five major areas of difference:
1) The high pressure regulator – On the first batch of BKO’s to be released, those without serial numbers, there were several that had regs that did not perform well with high pressure output tanks (those set at 800 to 850 psi). This however was remedied by a quick change of the plunger in the stock HPR and you were back playing again. This has been remedied on all markers since and is no longer and issue.
2) The Chip – The first batch also had some markers that contained a chip that was capped at 10 bps. These chips did not outlast the per-serial number BKO’s and some of these were released with the 14.9 bps chip. Newer variations of the BKO have been said to go up to 22 bps but you will not find a new BKO slower than 14.9bps. The older markers can be made to fire UL bps with the chaos chip. Fortunately, Defiance has announced that there are chaos chips available for the “2K3” style chip as well.
3) The ball detent – The earlier BKO’s had cocker style detents. These were replaces by an o-ring style detent and were one of the fist noticeable differences associated with the “2K3” title. The chip was too considered “2K3.”
4) The Trigger frame – The “2k3” also have a newer grip frame. It is rounder in the back thus fitting the palm better for some and remedied the issue of trigger slop in the previous frame. It cannot however take aftermarket triggers such as the vapor trigger. The previous frame could take this upgrade.
5) The milling – Simply a cosmetic difference. The first design released in bulk was a “expanding oval” milling. Later there was the diamond-shaped milling pattern. There is said to be a third patter, but I have yet to see it.
- Now here is the thing that makes them more variations than model designations: it is possible to get an oval milled marker with the 14.9 bps chip and yet have the newer style grip frame. Don’t let this scare you off though. There are no more of the faulty regs; none of the chips slower than 14.9 bps, and hard pressed to find one with the cocker-style detent (which is unfortunate in my humble opinion). The grip frames have also made the change completely but a few still can find the older grip frame. As for the milling just call the place where you are buying and check.
I have heard that the BKO's have problems with the regulators not being able to handle HPA tanks, is this true?
The original BKO's regulators did have problems with handling outputs from tanks over about 500psi. The regs have now been fixed, and that problem no longer occurs, unless you get a used BKO that is a "pre-serial #" BKO.
Is the stock ball detent bad, if so, can it be replaced?
Some people had trouble with the ball detents on the original "pre-serial#" BKO's not stopping double laoding. This was easily fixed by purchasing a cocker detent. On the current 2k3 BKOs, the detent is not replaceable. It is an o-ring detent, and has not had too many problems come up so far. You may want to stay away from "force fed" loaders like the HALO B and the Evolution2 on the o-ring detent BKO's because they are not as strong, and balls could be forced past the detent, and thus double loading could occur.
What barrel threads do BKO's have?
BKO's come with ICD threads (same as the bustmaster) from the factory. If you order direct from ICD, you can request a BKO with cocker threads. It is an extra 70$, but it can be worth it if you have a colection of cocker barrels already. The Murder Inc. BKO's come stock with cocker threads.
Can BKO's run on CO2?
Most people say that BKO's and many other electro-pneumatics cannot run on co2. This is one of the biggest misconceptions in paintball. For a guide on how to properly set up a BKO for co2, got to www.obdo.net
and look for the instructions on how to set a Bushmaster up for co2 use (it is the same for a BKO).
What is the difference between the BKO and the Bushmasters/Defiants?
The BKO's use a 2-way solenoid while the Bushmasters/Defiants use a 4-way solenoid. The 4-way solenoid uses air to move the bolt forward and backwards, while the 2-way uses a spring to return the bolt the the cocker position. The 2-way solenoid does allow for better efficiency of the gun, but cannot sustain heavy ROF's (rate of fire). The 2-way soleniod is said to be capable of no more than 17bps.
What is the HPR?
HPR stands for High Pressure Regulator. The HPR is what looks like a grip on the gun. It is used toregulate the pressure of the gun down to arounf 175-215psi. This air is then moved to the LPR for further regulating.
What is the LPR?
LPR stands for Low Pressure Regulator. The LPR takes takes the pressure given from the HPR and regulates it down to around 60-90 psi, so it is suitable to go to the solenoid.
Out of the package, what does the BKO come with?
The BKO comes with a manual, a 90* macroline fitting on the stock regulator, and a peice of macroline about 5inches long. It does not come with a drop forward, CA, any tools, etc.
Is there any type of schematic for the BKO, so I can see what the internals look like?
Yes, I have attached a link below:
What type of maintanence does the BKO require, and is it reliable?
The BKO requires almost no maintenence. Take note: DO NOT OIL, LUBE, WET, ETC. THE BOLT! It is made of derlin. If you use any type of oil or lube, it will cause the bolt to swell and become ruined. Make sure to take the bolt out of the top chamber and run a squegee through in the rare event of a ball break (NOTE: The bolt pin must be replaced in the bolt as it came out. Make sure the pin is locked into the hammer before reusing the gun. See the BKO manual for a diagram.) You may need to lube the stock hammer housing and valve pin after about 5uses or 7000 shots, whichever comes first. To access these areas of the gun, please email me for details!
How many shots can I get off of each size nitro tank? What about a 20oz co2 tank?
I think the best way to estimate shots per tank is to take the amount of Cubic Inches times the 10 for a 3000psi tank or 15 for a 4500psi tank. For example, with a 68/4500 tank, you should expect around 1020 shots per full fill. Keep in mind, this is the general rule for all guns and tanks. For the BKO, I would expect a little more than that amount per fill. I could get about 1250 shots with my 68/4500 on my old BKO. Now, on the other hand, a matrix might get less than that stock, because they tend to be gas hogs.
For a 20oz co2 tank, I would expect close to 1000-1200 shots per fill. NEVER USE UN-ANTISIPHONED CO2 TANKS ON ANY ELECTRO PNEUMATIC GUN!!!
Does the BKO have multiple firing modes?
No, it is a semi only board. You can buy and install aftermarket chips like the chaos and tantrum to allow MOF though.
Does the stock trigger have "slop"?
Yes, this is favored by many players, because it allows them to tap the trigger from the side and attain great ROF's. You can order directly from ICD and ask for a non-slop trigger. The vapor trigger and razor trigger are also a way to eliminate trigger slop.
Are there any "custom" BKO's on the market?
Yes, Murder Inc. makes a BKO with new milling and dust anno. It is purely cosmetic custom. No real preformance upgrades are added except that it has cocker barrel threading.
What types of upgrades can the BKO take?
The BKO takes most all of the upgrades a B2k/Defiant would take except for LPR upgrades, and the BKO does not need a regulator asa.
What are the best places to buy BKO upgrades?
Tantrumpaintball.com and vaporworks.net offer almost all of your preformance upgrade needs barrels, hoppers, and air systems. Check them out!
