Almost finished building my Tac-41 LS which is dedicated for night time use.
To clarify why it is built this way a few details about the rules of local night games. Almost all night games limit the muzzle energy to 1.5J, so high energy snipers are not allowed. The second thing is that almost all games require either tracer or muzzle flash device. If we combine these two thing its clear that the optimal build is 1.5J and .32 teacer bb.
Tl;dr kitlist:
Externals:
-Tac-41 LS-Silverback carbon XL suppressor
-Tac-41 short barrel base
-5ku picatiny folding stock
-Long mag
-FS bolt knob
-M-lok rail piece
-M-lok QD sling mount
Modification:
-stock front cut short
-picatiny surface modified to fit the 5ku stock
-external screws for toolless barrel removal
Internals:
-FS 200mm 6.04 inner barrel
-FS 101% seal
-FS 70° R-hop
-Silverback m140 spring + 10mm pretension
-SRS sport barrel spacer
-FS Mousefart 2.0 piston head
-FS POM Tac-41 rear piston spacer
This muzzle energy does not require high strengt parts in the cylinder area or adjusted piston weight, so the stock LS part will do good there. The only changes required are the Mf 2.0 to dampen the piston impact and a spacer for the rear of piston to reduce wear on the cylinder walls.
I was looking for an oversized overbarrel suppressor look, and fit a short inner barrel inside to keep the suppresson effective. Luck I had a leftover mp7 barrel from ages ago… Also used the old CNC barrel spacer which came with the previous series of SRS Sport rifles, thats fit just perfrct in the barrel base of Tac.
Kept the original chamber, since I found no issue in accuracy with it, paired with the usual 101% seal and R-hop matching the barrel.
The external modification were simple.Drilled holes to fit the external screws to remove the whole barrel assembly without tools, you can only do that with the LS because the polymer received is flexible enough.
The front of stock cut back one mlok to make room for the suppressor with the short barrel base.Also cut into the picatiny part where the folding stock connects.
It turned out to be nice and silent rifle to use at night, I will give it a spin in the daytime with only reddot because it’s just really fun to use and the weight is minimal.
