Following this post will help you bring out the maximum from your Tac-41. You can adapt the same concept to any version of the Tac-41 family, regardless the type or the length. Your only thing to do is match the variables to your field limits, such as sprint strength, R-hop hardness, piston weight and so on…
Tl:dr kitlist and link at the end of the post.
First off all we have to clear that what is an ‘upgrade’, it has to improve the function of your replica in some way and give you an advantage. It can be the effective range, accuracy, durability or even comfort.
In most weapon platforms you actually NEED the upgrades just to reach basic function. However the Tac-41 (and also SRS) are fully capable sniper platforms out of the box with a spring change.
Let’s begin with the cylinder area.
That part is the powerhouse of your Tac-41. Have it performing flawlessly and stable is a key role in accuracy.
I personally use the Silverbck VMP piston paired with my Mousefart 2.0 piston head. It’s the same as the current red version, just old. The tuneable piston weight allows you to find the highest J on the BB weight you use, if you are doing it well you will be able to use a lot weaker spring to reach the J you desire. /There are a whole lot other factors involved, explain all would take a whole article./ The Mousefart 2.0 is the final version of my airbrake piston head. The brake is flexible rubber, so it will not break on the long run even if the nozzle bore is not drilled exactly centered, but always seal properly. A well tuned rifle can reach as low as 45db on 3J+ muzzle energy level with this piston head.
When you have a good piston head and a good suppressor, all the noise signature left is the annoying twang sound by the vibration of the spring. With my spring guide the V.R.A.G. you can adjust the thickness on the end of the spring guide, that elliminates vibration without additional friction on the guide.
In case of lite-sport variant, you have to replace the cylinder and cylinder head on the long run. Out of the box the function is perfectly fine, but for the sake of longevity you have to replace the alu parts to the steel versions by Silverback.
Let’s see the hopup are.
My choice for chamber is the original Silverback cnc version, you can apply a similar setup for the sport lite polymer chamber too.
With 101% seal, matched to the R-hop for the 6.04 hybrid barrels. For my field limit the 85° is the ideal for most of the year, but you can choose the right hardness for the J you play at, for example my night time Tac-41 set to 1.5J has a 60° R-hop.
Also I use the Silverback advanced hop wheel, it is adjustable in much finer increments than the stock wheel. The wheel itself has a smaller range of adjustments too, so you can pair with the higher or lower nub it comes with, and each click of the wheel will have less effect of the lift. Also if you simply remove the clicker from the chamber you can adjust the wheel without steps at all.
However a metal bb stopper included in the kit, I see no reason to use it instead of the plastic original.
Regardless the type of CNC or polymer chmebers I use my own 6.04 id barrels, that is kind of obvious tho.
The barrels in airsoft hase the worst improvement to cost ratio, but if you wan’t the maximal potencial, you can not skip that part.
In case of Silverback the original barrels are decent, if you want to improve you can’t choose a medium grade barrel.
I would like to add a side note, because I consider the BB the part of the hop are. If you buy good quality it’s great, but it does not give you much advantage, most of heavy BB on the market already good, regardless how BLS branded it. What actually gives you an advantage is adding a little more effort to it, and clean and sort them by 0.001gr. A jewellery scale is only a few bucks, and you can sort a whole bag in little more than an hour or so… If you think about how much effort, time and money we spend on this hobby, adding this little more is really not a big deal, even if it’s sound so.
This sums up how you can bring out all the potencial from your Tac-41. In theory you can apply the same concepts to all platforms.
Have fun building your own rifle and do not forget to work on your skills to match the rifle!
