Ordered a HDD for my QB

[dryanw]

I ordered from the retailer who is not to be named. Anybody have one and have any tips or comments on it? Also ordered CDTs tune kit. I plan on installing them at the same time.

I had heard the HDD in question was flimsy, poorly designed and ineffective. I have no personal experience with it so let me know how it works out for you. I am curious.

i read gluing a piece of felt to the back of the hammer has a similar effect ........ anyone tried it ?

I have tried 2 of these HDD's and did find them to be very flimsy. Due to interference with bolt operation I removed them. Highly disapointed in the product's construction.

Well that not worthy....I may return it based on these reviews. Can anyone elaborate on the felt thing?

[dryanw]

Anybody? Sorry to bump the post....

I have one of the mentioned items from the same retailer. I ordered the gun from him all tuned up. I have no trouble with the bolt and since I have never fired the gun without it, I don't know if it works or not.  can any one tell me how one would know the difference?

I'm going to go ahead and give it a shot, as it says on the website that the design has been improved. I have fired my gun without it and get about 50 shots with 2 powerlets. I will report on the results. Although I do plan on doing some mods that may increase CO2 usage at the same time.

Well, I got it in and got about 40 shots from 1 co2 cart so there was some improvement. However im a little peeved I spent that much on a tiny piece of metal. All it does is make it more difficult for the hammer to travel in the rearward direction. You could make one yourself.
