TM v3 question

[Dart]

Alright I am kind of stuck between a rock and a hard place here. I have a TM ak47 that has seen roughly a season and a half. probably about 15k rounds.

Anyways I caught the upgrade bug and started to do some work to it. I picked up a set of oiless metal bushings and a new spring. The spring is a systema m120.

My question is would I be smarter to take that m120 back and get an m110 in there or will the stock gear box *aside from the bushings I know thats a big weak point* be able to handle the m120? I was thinking that maybe just a new spring guide may bring things up to snuff for it.

I have done some searching and am getting mixed opinions, unfourtinatly most of the info I can find on this seems to be for echo1 and JG.

I know you can't give me a definate answer of *yes your box will blow* just curiouse whats going to be the less head ach route.

BTW i know the fps does not make the gun and dropping to an m110 won't make it any worse, how ever the extra bit of penititration from the m120 will be very nice as we play in alot of bush.

Thanks in advance

My advice, M110, tightbore, high quality hupup (my choice is guarder clear but other swear by firefly), bearing spring guide, and metal bushings.

would the stock spring guide work with the m110? I Am on a bit of a budget build here. I mean I guess its only about $25 for a prometheus one....

As for the barrel... I have a stock TM one thats good enough for now and the TM hop up is plenty reliable.

Work up to it i guess. But with an M110, yes your TM internals will last for awhile, just not as long as they did with a stock spring.

The tightbore and hopup rubber are the real FPS boosters if you get a good set and add no extra strain on the mechbox.

+1 to all this. M110 spring should put you in the 360-370 fps range on its own. The bushings will keep your gears stable. The tightbore will increase your power, range and accuracy. The hopup rubber will increase your range and accuracy, and in some cases, velocity as well. The bearing spring guide will give your gun better consistency between shots and possibly increase velocity a bit. THat should put you just under the 400 fps mark.

However, I would strongly recommend against getting Systema springs. Do a search on the forum and you'll see that Systema springs tend to be highly problematic. I'd personally recommend a Modify spring. In my experience, they've been the most consistent springs I've seen to date. I used to like Prometheus, but I've gotten too many duds from them.

A metal spring guide would be a very good idea for longevity sake, especially with a higher powered spring.

ok cool I think I will take this m120 back than. Now he sells PDI and Systema out of those two what would you recommend?
