Solid, well built product.

After having some bolt stick issues on one of my two TiPXs, I compared the breach blocks and noticed how roughly milled they were. One breach would cause bolt stick and the other would not, even if I switch the bolts between the two markers. I picked up a Killhouse breach block for both markers, as I did not want to deal with any problems due to the low quality milling on the original breech block. Just simple look at the difference between the stock breach block and the Killhouse one. Killhouse is a huge jump in quality.

Simple, easy install and it cured my problem. Bye-bye bolt stick. And will also allow me to shoot first strikes if I ever desire to.

Bottom Line: Recommended purchase. Cured my problem, adds versatility to marker.

I bought the KWS First Strike Block as soon as i herd it was in. It works great with first strike rounds as well as regular paint. the only 'downfall' i found was that i had to take out the o-ring from my original block that held the barrel snug (it came out easy with a dental pick or paperclip that was bent at the end). i would highly recommend this item to anyone with a TiPX or TPX pistol that wants to be able to shoot first strike's out of their sidearm.
