elite force IWI Tavor Tar-21 upgrades help
Just picked up a IWI tar 21, looking to increase range and power on it, after being on the field roughly 4-5 times, find that the drop and velocity of the bb's is a little less then many other guns I've seen, this is also going off minimal knowledge of upgrading an airsoft gun. if anyone has suggestions or has had experience with this particular gun, please let me know!! would love to make this thing a beauty.
looking into new BB's also, was thinking .25 seamless. |

What FPS does it shoot at now?
Sounds like you've been using crappy BBS. Most stock guns are fine if you run good ammo through them. 0.25s are too light for nice groupings in outdoor play. Before you open the gun, try running some high quality 0.28 or 0.30g BBs through it. BBBastard, Madbull, etc.

was using 0.20 bio bb's that were not the nicest bb's offered at the fields. just ordered some seamless bb's 0.25 and 0.28's to test this out more, as well as silicon spray for the barrel.
still curious on hardware upgrades also. if extended barrel is worth it.. or other necessary upgrades for improved performance. |

The stock barrel length is more than enough. Also, despite what the manual says, do not put silicone in the hop up chamber. The hop up works via friction. Greasing it removes the friction and will make your gun shoot like balls.
You should, however clean the barrel.

the silicon is only for the barrel, not for the hop.

Well there's your problem right there!
Putting silicon spray in the barrel is totally bad and you should stop doing it immediately. The reason for this is that it will leave residue in the barrel which will 'grab' bbs and actually slow them down in transit through the barrel. For optimal performance, you want your entire hopup system, rubber, and barrel to be anally clean and dry. Tear it down, go to town, and report back if your problems persist. Edit: Silicon spray can be used as a solvent for soaking, then cleaning the barrel (when it is entirely separate from all other parts), but you really have to go to town when swabbing it to make utterly sure beyond the shadow of a doubt that there's nothing left behind. Windex is preferable. Edit 2: Beyond residue affecting bbs on it's own, it is a magnet for dirt and gunk. Your barrel will foul quicker, especially on bios.

Lightweight silicon oil is used to lubricate the valves and working parts of gas blowback systems. The reason why it's used is because silicon lubricants are not petroleum based, and therefore don't degrade other petroleum based materials (rubber, most plastics).
Silicon spray isn't used for much, because the accelerants and/ or additives used are typically petroleum based, and therefore can cause problems over time in systems made of rubber or plastic. In 'safe' silicon sprays, the nasty stuff will evaporate over time, and so can be safely used as a solvent to clean metal parts, but it's still not stuff that you want to spray on your gun/ down the barrel etc. Similar to the 'WD-40 vs. Bicycles' issue, it is not a lubricant, and should not be used as such. |

any thoughts on hardware upgrades that are worth while??

There's lot's of threads on this, and age verification will help greatly, but a general rule of thumb is that your compression system (piston, piston head, cylinder, cylinder head, nozzle) will benefit you the most, a hopup unit to match the nozzle will make all of that minty, and then a nice barrel is icing on the cake.
Everything else is to increase or manage ROF, longevity, trigger response, and all that stuff which makes the gun perform the way you need it to. Start with mastering the use of your system the way it is now, read up on all this stuff in the meantime, and when something breaks you've got a great excuse to drop some money and get to work. |

Jumping on the subway so no time for a proper post, but number one tip is upgrade your bb's. 0.28 or 0.30 BB Bastard is a good start. Makes a huge difference.

Seriously listen to this carefully.
1. Buy high quality BBs 2. Clean your barrel (no silicon oil !) 3. Adjust your hop up properly Nice and easy. You'd be surprised by the difference this 3 easy steps make.

you should never have to oil anything in an airsoft gun outside greasing components inside the gearbox maybe once a year or longer.
oil in mags or bbs or barrels is a last resort diagnostic action for very specific purposes. silicone oil MIGHT or CAN be used to clean a barrel if you spray some on a cloth and run it through the barrel and follow it with a dry cloth to wipe it down aggressively. You never leave oil in a barrel. As for accuracy vs precision... you can make your gun accurate, but add consistency and you will have precision. So check the factors that contribute to consistency, mainly air seal. When you chrono the gun with whatever weight, does the fps fluctuate a lot? +/-5 fps is good, less than that is great. More than that you will need to start thinking about piston o-ring or cylinder head seal or nozzle to cylinder head or nozzle to bucking, or bucking to hopup. All these air seals when functioning properly and not leaking will give you a very stable fps from shot to shot, making your gun precise because you know where BBs will land all the time, and you'd not shooting with a hope and a prayer than one out of your 20 lands where you are aiming.
