Hello Guys,

Usually the reason for buying a non-stock bolt is to lower your operating pressure, so the lightest spring is going to allow you to lower your pressure the most. However, I had issues with the TECHT bolt in my TM-7 so I threw it out and got the Boss bolt instead.

When did you send the email? It has taken a day after the weekend for their tech to respond to me. If you can call, that's always the easiest route.

i sent last 12/09, to support and todd.

You can definitely try the TechT springs with the stock bolt but the lightest might not have enough power to return the bolt. Give it a try, if you find it's not feeding/firing, try the next spring up.

thank's for help, and, i let you know the results.

hey great to read you again english. A while back,, you helped me out with a jammed selenoid/massive air leak. Good to see you still give sound advices

Stock I've tried the upgrades and barely got over 265fps go back to stock nothing wrong with it

I personally have found great results with the TechT delrin with the Axe, TM7, and the TM15. I had to start with the medium spring until the bolt was broke in a bit and switched to the lighter at that point.

is ther an after market stock (tan) i can use to replace the original black one? I got the terrapat tm-15 with a cut down shroud but i would like to get my hand on a tan stock, like the soggy. And why not a tan mag???? Where can i get those

TheEnglishGuy · 03-26-2012, 06:41 PM

For the stock you could try this one:

The TM-15 uses the same connection as the Tippmann 98, the only thing to be aware of is that there's some overhang from the body at the back, so some stocks might not fit well.

For the magazine you'd need to find an Airsoft Tan mag and then modify it to enable you to fit a battery in it.

Thanks English. As always, you are right on the ticket.

goodpedro · 07-25-2012, 08:00 AM

I guys, since I love the stock on my tm 15, i do not want to buy a dark earth ar-15 stock that doesn't look as good as my original stock. I found a replica of my original tm 15 stock on an airsoft site (dark earth) but i really wonder if it can fit, any suggestion. (it's a magpul replica) here is the link

Hey guys

do any of you know what a good sight to purchases the Boss Bolt kit for a BT Tm-15 Le? i herd this is the best. I just got a new Tm 15 and all it does is break paint. Looking on here it seams that everyone has the best luck using better paint and replacing the bolt with the Boss. I am just having trouble finding the correct one. any suggestions?

Thanks English,

do you have any good recommendations for a barrel? what would be the best one to purchase?

JlNXX · 03-25-2013, 07:57 PM

I haven't had much luck with the tech t upgrades. The bolt worked well (really reduced kick), but when I added the spring kit even the stiffest spring would not fully return the bolt after the first shot. Because it wouldn't fully return the eyes would see the bolt in the breach and allow it to fire again. I scrapped the springs for the Tm, and they work awesme in the tipx. I recently added a rampage board and am now having the same bolt return issue. What would keep the bolt from returning fully? I have tried the self set mode on the board and it doesnt seem to help at all. As far as a barel upgrade for the tm you can lok up super stanchy customs on facebook and get your stock barrel, freak drilled, to maintain the built in silencer function, and gain some efficiency.

TheEnglishGuy · 03-26-2013, 10:42 PM

Barrels are tricky, you'll find that everyone has their own personal favorites. My advice is to start off with a few lower priced barrels in different bore sizes and see which works better for you. If you don't find anything perfect, start spending a bit more. Ultimately you need to choose what it is you're looking for .. looks, efficiency, accuracy, tip options, bore sizes, porting etc etc and then start with what you consider the most important.

If you want somewhere to start, Flasc and Lapco both make nice barrels that look good and have lots of options.
