Marketing the plastic as "self-lubricating" could cause misconceptions about proper gun lubrication
The Orange Howitzer Bolt, to say the least, is perhaps the best cost-effective investment you can make toward your Tippmann 98 custom. My purchase was made at 23.95, and to may infinite dismay, I eventually discovered that it is not uncommon to see this product advertised at 19.99.
The Installation of this bolt was extremely simple. While it does require dismantling the receiver, it is not a marvel of mechanical prowess. You simply remove the bolt-hammer connection bar, remove the old bolt, insert the Howitzer, reconnect the connection bar, add 2 drops of lube and re-screw the 6 receiver screws. I have read the reports of some people having to sand their receivers to accommodate the Howitzer, however, this is not a problem of mine (My 98 custom is in the 810000 series of serial numbers. If that makes any difference whatsoever).
I then proceeded to fire 3 separate, ten-shot groupings at 25ft, as I had performed previously with the stock bolt.
The stock bolt stayed within a grouping of 12" on all three trials, with only 1 or 2 of the ten shots fired straying from a grouping of about 6 inches. These "rogue" shots have seemingly disappeared with the addition of the Howitzer.
The Howitzer groupings, on all three tests, never surpassed 4 inches, with the best grouping being 3 1/2". All rogue shots have been eliminated completely. (All MOA test-fire tests were performed with the stock barrel)
My gas efficiency has also gone up. Using a 9oz CO2 as my controlled variable, I was able to fire 394 rounds with the stock bolt before losing gas. The Howitzer upped the shots to a solid 515.
As stated previously, this is a necessary product for your 98 custom. Between the outstanding MOA accuracy increase, as well as a sufficient increase in gas efficiency, the 19.95 will eventually pay for itself.
