More spare o-rings would be nice
I bought this bolt from Badlands after about 5 months of using my PMR. Looking at it, the bolt looks slightly different than the stock bolt, as the long skinny back part (no clue as to the name) has been completely removed. Instantly I was skeptical about the bolt (not sure why). i paid 89.99 for this bolt, and hoped it would improve my PMR.
As i removed the bolt from the package i found it to be slightly lighter compared to the stock bolt.
Putting the bolt in my marker was extremely easy, remove the old bolt, remove the back cap and can, remove the o-ring from the bolt,grease, screw on the can, replace o-ring, put back cap on, install Allen screws,Grease again, insert in gun. It took longer to type this out than it did to install the bolt.
I gassed up my marker, turned the eyes off, and listened for leaks, none, so far so good.
I pulled the trigger once and i barely felt the PMR fire, the only indication was the sound, which i found and been slightly reduced.
Using PSP ramp set at 26 bps and a stock setting dwell, the bolt had absolutely no problem cycling. I found my stock bolt to occasionally not reset, as in open the breech when i was firing at this bps. I'm not entirely sure why, and if anyone can enlighten me, comments would be greatly appreciated. Also anyone who has used this bolt and can help me with an optimum dwell.
I loaded up my halo, and let a rope of balls go, i couldn't believe how little noise and kick there was. Shooting single balls i saw the accuracy was insane.i know there is debate on the fact that a bolt can improve accuracy but i believe it.
With the stock bolt,a 48inch 3000psi tank and a good paint to bore match , my rail would only get about three full Halos out of it. I haven't fully tested this new bolt by playing a game and going through pods, but after my test run and single halo worth of balls and a not great paint to bore match, i found the air consumption to be less already, and i will update this review after i can run a tank dry by shooting hopper after hopper through it.
Played a big rec game, and much to my dismay, my proto would not crono under 340 fps, and when turned down, the bolt would merely fire halfway into the breech/ about to the eyes and get stuck, im not sure if this is a problem with my regulator, but it was working fine under 290 fps with the stock bolt. My dwell was at 24 by the way, 6 more clicks on the board than what the techt guys say you can get away with.
Emailed Todd at Techt, received an email back within a day, with suggestions on how to fix my bolt problems, used them, bolt is fixed, moving the rating from 7 to 10 after extremely helpful customer service, and a quick problem fix. Tweaked marker further, found mine works best at 20 dwell. Be sure to lube o rings properly and continually with this bolt. Velocity problems can arise with improper dwell settings matched with fast bps rates. Spend a day with a lot of air to properly adjust the marker how you want it. best possible time to do this would be with access to a chrono and lots of air and lots of paint and to be patient. If this bolt does not work for you, spend time on it, and your marker will be up and ripping in no time.
This was some of the best money I've ever spent on my PMR.
Check this bolt out when looking for a new one.
Its an awesome internal upgrade for a great marker.
The price leaves something to be desired but oh well, thats paint ball.
I'd give this bolt a 10 but ive only had it for a little while, and there are some bugs, it started leaking on me. but i will update accordingly.
Couldn't play a big game due to problems with this bolt, marker wouldn't fire once turned below 300 fps. Dropping it from a 9 to a 7
Fixed problems, very helpful customer service, will continue to buy Techt gear.
from a 7 to a 10
10 out of 10

The leak was just an o ring that popped out of place, i think it was from having my velocity that extra 10-15 fps higher... don't quote me on that though. I haven't had any more leaks at all since i fixed that one. as for fixing it... i just pushed it back into place.
um, i had a major problem with it, my marker would leak out of the bolt, after blowing three orings before a big game, also the marker wouldnt cycle completely, and when it did, it was way way way over the legal 285 at the field. the bolt would stick at its full strike.. not really impressed, my dwell was 24...... i havent found it to be reliable at all to be truthful, im quite angry with it. im working on fixing it and will post accordingly
To help with your problem i have the same bolt in my PMR. I looked into the L7 bolt a little further. If you haven't turned your ABS (anti bolt stick) down to its lowest setting or compleatly turned it off you will experience the bolt sticking problem. I have had almost no problems with my bolt sicne i have installed it in my PMR. Just remember to tweek you dwell. My dwell is set at 18 and just like they said on their sight there is a majic number for every configuration. Hope this helps. In case you don't have the sight here it is.........http://www.techtpaintball.com/raill7install.html
Since you got all the kinks worked out how has the bolt worked? Is there much kick (compare it to stock please)? Have you even played a single (full) day with out having to jack with it? Would you still recommend it after all the problems you have had? If the stock bolt is 30+ bps capable, it really isn't necessary for speed... Kick, lower dwell (making it easier to cycle faster) and possibly accuracy(?) seem to be the main point for changing it right? Does it accomplish these things?
