I Know What You are Thinking...

While the telescoping Impact muffler assembly is a great idea and an efficient way for going back and forth between quiet and more quiet, where it is positioned makes a YUUUUGE difference with respect to accuracy.

After testing a few Impacts, i discovered that it depends on whether the muffler is at 12:00, 3:00, 6:00 or 9:00 in its final position… and the position may be different in its collapsed or extended position; for example, 6:00 may be the most accurate setting in collapsed mode and 3:00 in extended mode, or vice versa. It depends on the Impact regardless of caliber because each and every Impact has its own personality, even identical twins.

To be specific, I have found for that for a given Impact, 12:00 might be 2mm groups, 3:00 4mm groups, 6:00 to be 0mm groups and 9:00 to be 3mm groups in collapsed position and different size groups at 12:00, 3:00, 6:00 or 9:00 in the extended position. So for accuracy, you have to remember the settings for the two positiions. If you have 3 different calibers you have to remember 6 settings… and what happens if you forget?

If you don’t want to go through having to remember the positions all of the time, the solution is simple: remove the telescoping muffler assembly and replace it with a Dirt E. Harry Precision Muffler. This way, your accuracy stays constant and you don’t have to memorize any settings. After all, you know in advance if you want a quiet or loud report.

Note: if you want to remove the telescoping muffler assembly, you will need a specialty spanner wrench that you can make from a 1/2” drive deep 5/8” socket and a die grinder… you will also have to heat the rear cap to break it loose. Or, if you would like, ship your barrel assembly to me and i can remove the telescoping muffler assembly for you- $50.00 plus shipping to you.

However, if you purchase your Impact from me, the removal of the telescoping muffler is a no charge. The Dirt E. Harry precision muffler is a mere $295.95 for .177, .22 and .25 calibers and $349.95 for the .30 caliber because of the increased ft/lbs.

Extra barrel assemblies with pellet probe and magazine are available for the four calibers on the FX Accessories Page.

Let me know what flavor(s) you would like to order, and I will send you a PayPal invoice.
