SMK QB/XS/TH 78/79 Modified Piercer Body Summary

SMK QB/XS/TH 78/79 Modified Piercer Body

Modified Piercer Body, High Flow for the SMK QB/XS 78/79 models. This does away with the tube, gauze, filter and steel washer. Do not try to fit the Tube, Filter, washer or gauze into our valve piercer body, we have made ours for more efficiency and power. Helps to bring the gun nearer the UK limit of 12 ft. lbs. Standard they are normally between 6 to 8 ft. lbs. The QB/XS guns can exceed the legal UK limit so keep an eye on the power after any work you do. Bedding in and temperature can affect the power so check regularly. The standard hammer spring can be shortened to reduce the power if required. 

The second photo shows the modified inside.

We have done two extra part drilled holes in the end so that they could be drilled through to gain a little extra power, but don't waste your time drilling them through as they don't make much difference.


Always check the power to make sure the gun does not exceed your limit, after changing any parts.

You can watch the video for free on this site under SMK Stripdown Video on the left side panel store links, at the moment it is the fourth one down. This video is on the XS 78 but the XS 79 with the large 88 gram bottle has the same parts inside but has extra seals.
