Dead On Paintball Pro Seal Front Bolt & Power Tube Reviews
Dead On Paintball has improved on the stock Tippmann power tube and front bolt. It's very smooth because of a precision Teflon insert running on a precision CNC machined billet power tube. This upgrade will improve air efficiency and should increase cycle rate.
This is compatible with the Tippmann Response Trigger System.
The Dead On Paintball Pro Seal Front Bolt & Power Tube is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
I've only put a case of paint through this item. The marker fires very consistent, as it did before the upgrade, the action sounds a little different with the metal parts, too.
Concerning ROF, I see no difference. RT appears unaffected.
I had to sand and polish the receiver internals due to the overly tight fit. I'd suggest doing this regardless of which bolt/seal combo you use. Less friction is always good.
After 2000 shots, it has caused a few small scratches in the receiver. I'm not sure what to think at this point, as it's nowhere nearly as bad as the scratching you'll witness on a stock Spyder. I couldn't imagine this causing problems down the road.
Back to the ROF issue. A shop as big as DOP could take 10 minutes out of their busy day to show us some evidence of a ROF increase with this item. I really hate it when a reputable company will turn to generic marketing tactics, making false claims, to sell a part. The shape and weight of the front bolt is identical to the stock bolt, so I would like to know how it could change the ROF.
If you want a metal bolt, then this is for you. Aside from misleading statements concerning the performance of this part, it works as expected. I would suggest saving the $40 and sticking with the stock internals until someone release a more exotic upgrade that actually causes improvement in the functionality of the marker.
I know a rating of 3 is harsh, but this is due to the misleading claims and high cost. If they marketed it soley as "It doesn't break like the factory one!" I would have given it a 10.

Veryg ood and durable
Makes gun louder then usual
I have been using this in my gun for over a year and we play a scenario game almost every month plus practices I have shot over 10,000 rounds through it nod no problem what so ever I has held up great. We have 12 members of my team and I am the tech person and have had the stock power tubs wear out and crack. It also seems to give a little more distance and a tighter pattern.
And the louder throaty sound lets the enemy know that the big gun is on them.
I have recommend it to all those how ask and made it a requires part for the team to have if I am to maintain the equipment

First off, if you are looking for some kind of performance improvement from this product, you are going to be disappointed. I have noticed some differences, but they are slight. It does appear to improve the shot consistency a bit. However, it also lowers the cycle rate. If you are shooting stock or E-Triggers, you probably won't notice the difference, but you will with an R/T; it makes it harder to find the sweet spot. On a lesser note, there really does seem to be an increase in noise, but considering how loud the A-5 is to begin with, well...
The aluminum parts are, obviously, more durable then the stock plastic ones. DOP's QA definitely seems to be lacking though. I personally have't had any problems with leaks, but then again I made sure to wash out the metal shavings that were still inside. Then I got to polish them smooth. Suffice it to say, I was less then thrilled. I was even less happy after handling one of JCS's nice anodized power tubes.
After polishing and oiling, I have had no problems with mine, but no significant improvements either.
If all you want is a power tube you aren't going break, get the JCS tube. If you are looking to improve the performance of your marker, get a new barrel, get a reg, get a can of NEVR-DULL and polish its guts, but don't bother with with this.

Has leakage problem in beginning then breaks the valve inserts
The pro seal was decent because it was steel but i had problems with it and if there was any other reason why my internal valve o-ring was falling out i would apreciate it if someone wrote me because when i first started shooting with it i saw the o-ring that holds the washer in place shoot out of the gun but then at a tournament a few days later i had no problems so i am not sure thanks
i am not satisfied with the product and if i could get a refund that will be happening soon
