Utah Airguns had a couple Impact Compacts come in. I jokingly asked the salesperson if they would sell me one. The owner was literally out trying it so I was told to text him. He agreed to sell it. ?
These things are amazing for the high shot count with a 300 cc bottle. I went for the .25, 70 shots per fill shooting JSB .25gr at 900 fps. My son shot it and wanted one too. They had one .22 and also agreed to let him buy it. I was surprised because they usually keep them for testing and to customize. His is getting 100 shots per fill. ? I can't think of another shorty that has a high count magazine and high shot count. Bottle is removable so I could also carry a 480cc bottle and really shoot for the day. All the regular Impact accessories fit it as well. 500 mm barrel and 300cc bottle are the only difference between it and the standard Impact. So once released standard Impact owners could buy the barrel and bottle and have a Compact.
The secret is in the Power Plenum. Increased plenum volume allows for lower regulator pressure so you have more usable air. I'm running mine at about 90 bar compared to my old standard that is around 140 on the reg. So that gives me an extra 50 bar to shoot with.
Older Impacts can have the Power Plenum installed. I was told they were having trouble keeping up with the demand and would not be able to get my older Impacts upgraded for some time. Being a bit impatient I decided to buy the new standard as well. Yesterday they informed me they had upgrade kits available. Great, now you tell me. ? So I dropped my non Power Plenum Impacts off today for the upgrade. It replaces most of the internals so it will be the same as the newest guns.
My only disappointment is the noise. The .25 without a moderator is LOUD. With the Donny FL installed it's more than backyard friendly. This just adds to the length though. My sons non-moderated .22 is much more quiet and he doesn't need the moderator unless he wanted full stealth mode.
Compared to the stock Impact with a 700 mm barrel.
