Review: For anyone still on the fence…

So far I’ve shot 1 case of wrek elite 1 case of xball bronze, and half a case of midnight with this bolt…

5000 balls, no breaks… period! (day started at 72 deg f ended around 85 deg f)
(the wrek paint was nearly 2 months old since I bought it, the midnight was 1 week old and the xball was brand new)


4500/68 tank
I filled 3 times (twice on field, once before I got there) my tank read just under 2500 psi at the end of the day(but you can’t really trust the gauge)

Firstly, I wanted to say that this IS an upgrade from the L7 bolt…

To prove this I first set up my Ion with the L7…
chrono’ed it at 285fps +/- 3fps
then took apart the Ion, installed the HP bolt, went back to the chrono…
Fired 10 rounds at 1bps, then a few 3 round bursts registering 19 bps, then back to 1 bps for another 10 rounds to confirm I was shooting between 295-300fps…

I then had to turn my reg down to compensate for the lighter more efficient bolt…

HP bolt IS more efficient then the L7 bolt because it needs less pressure to shoot the same FPS when compared to the L7

(this is due mostly to its lighter weight, and better flow characteristics)

This bolt is also much more durable then the L7, and easier to install

(you don’t need a screwdriver carefully placed into the firing chamber to tighten or loosen the end cap)
(This step is proven to contribute to early failing of o-rings, if you come into contact with the o-ring with the screwdriver…which is nearly impossible to avoid)

The stationary core is thicker, more durable and can be installed by hand… (caution, people with weak hand grips should use lock-tight on the end screw as it may back out if not tightened properly)

(probably around 10-12 inch-lbs for those people who have digital torque wrenches)

The Aircraft aluminum bolt is also thicker and more durable then the L7, with significantly fewer stress concentration points… I can guarantee that The back of the L7 will break off long before the HP bolt would even nick…

Lastly, in an outdoor (open field) environment, with little background noise, a 5mph wind, 71 deg ambient temp, at 4 inches to the side of the muzzle, the HP bolt measured 8dB quieter then the L7


To sum it all up:

HP compared to the L7 is:
1) More Air efficient
2) Easier to install
3) Stronger/more Durable
4) Quieter


But… they are BOTH OVER PRICED!
Conclusion: Overall the bolt is a real improvement over all other bolts, but it is just priced way too high for what you are actually getting...

This bolt is deceiving on its claims first weight, it is lighter but that is not the only component of this bolt you must take in account the "stalk" that fits inside the firing can that the bolt rides over. The two components together have a greater weight than the L7. Efficiency is not due to just the bolt but a combo of the the two components together, similar to the way the Epiphanys can inserts work, by filling the space in the can it uses less air to drive the ball, same concept. When you get the L7 you get a new stop and just a bolt so its weight claims are pretty close to on the money as far as air use the Hollow point is only slightly better on air than the L7. Last the durability claim has no basis, the L7 bolt has never broken yet, I have talked to Todd at tech T and no L7's have broken yet, so how did you come to the conclusion its more durable??? AT best you are speculating on the "stress points" of the L7. I have fired at least 20,000 balls with my L7 and there isn't any sign of wear on the bolt at all. Both bolt have strong point and weaknesses its comes down to customer preference more than anything else to which is better.

Check out Ionowners.com, there is at least one person with pictures of an L7 with a broken stalk...and several others who make the same claim

the L7's weight is only quoted on the section that moves, which is the only part that you really need to concern yourself with in this instance as you're not using any more air to move the stock section. so weighing that portion of the bolt makes absolutely no sense anyway. in that respect the deadly wind bolt is lighter and more efficient than the L7.
