HALFBLOCK HAMMER SLUGS, mQ pilot seals
« on: July 17, 2009, 09:26:09 PM »
Some parts for sale, some odd, some hard to get:



HALFBLOCK HAMMER SLUGS

What is it?
The hammer slug is an add-on weight for your sniper or autococker hammer. It was designed for halfblocks and midblocks, which experience significant hammer assembly lightening. It is made of a heavy tungsten alloy which replaces the entire weight of the cocking rod.

The hammer slug can also be used on a full-body marker as a heavy cocking rod knob, or in other applications when hammer weight could use tuning.

Why use it?

One of the first things many people notice about halfblocks and midblocks is that the spring tuning changes. This is because a half/midblock uses a slotted hammer and does not use a cocking rod. This amounts to around a 33% weight loss in the hammer assembly, which necessitates springing changes which often include a heavier mainspring or higher IVG setting. This means that cocking force requirement increases, leading to a higher LPR setting or a heavier pump stroke.

The hammer slug replaces nearly all of the lost weight* and allows a lighter spring tuning overall, leading to a lower LPR setting or a lighter pump stroke. If you are halfblocking an already tuned marker, the slug can help keep retuning to a minimum.

* Halfblock hammer + slug = 97-98% of the weight of a stock 2k+ hammer + stock cocking rod



How do I use it?
Simply screw the slug into the back of the halfblock hammer and re-assemble. You don't even have to remove the hammer to do this. Blue loctite is recommended to prevent loosening.

For use as a cocking rod knob, remove the current knob, transfer the set screw from inside the current knob into the slug, and screw the slug back onto the cocking rod. Tighten the set screw to lock it down. Blue loctite may be used if loosening is an issue. For ultimate mass, a second slug can be used internally by cutting extra threads on the cocking rod.

NOTE: The halfblock slug is not compatible with midgeted guns (shortened bottom tubes) or guns with hammers that don't have cocking rod threading.

Price
SOLD OUT - Sorry!

Please let me know if you plan to use the slug on a full-size cocker.

MQ VALVE PILOT SEALS



These are the urethane "dot" seals for mQ valve pilot assemblies. In my experience this is the #1 wear part in an mQ valve. Sometimes the new 90 durometer (black) seals can leak as well. These are 80 durometer seals (natural color).

Price
$4.99 for 3 seals, shipped within the US.

More parts later.

All sales are Paypal only. Contact me for international shipping.

depends what you mean by micro. If you mean a PTP Micrococker, it should fit.

Depends if you mean mini or midget. If mini it's fine, if midget, it won't fit.

Mini is shortened in the front, midget is shortened in the back.

Apologies folks, while it doesn't really amount to anything in practice, for the sake of accuracy: the mQ seals are 80 durometer, which is the original mQ1 spec. I got confused a while back between some o-rings I bought that were 70 durometer and have been using the wrong figure.
