    100 SHOTS PER FILL: Seneca Aspen and Nova Freedom

    Even better, choose between filling your Aspen or Freedom for 20 or 100 full-power shots in the moment, to suit your needs. Before I describe the simple plumbing required, may I explain why I think this will prove a popular mod? Shooting the Aspen exceeded my expectations. However, the pump has...

    Aspen and Freedom: New Third Stage Pump Head Replacement?

    See the photos. I note that these replacement third-stage pump heads are very similar to those in the Seneca Aspen and Nova Freedom. Ten (10) of them for $5.00 USD with free shipping from China. Other photos show the sealing ring being two-piece - an o-ring and adjacent sleeve. Perhaps these...

    HEY, BEEMAN: Please build my next gun

    I added to my QB78 collection by buying a QB78S at a giveaway price. I assume they weren't a big seller at Walmart. The synthetic stock seems extremely well made and fit. That said, the weird pistol grip and look-through butt are a pain at the shooting bench when using a rear bag, and the gun is...

    Pump Problem - Seneca Aspen

    My Seneca Aspen is about 30 days old. It has fired about 1500 shots (virtually all at 2200/2000 psi). I lubed the gun as instructed, and then followed the maintenance instructions faithfully (lubing at the shorter intervals as instructed). I stored the gun at the proscribed pressures...

    Nova Freedom or Air Venturi Seneca Aspen Question

    Hello. I'd like to buy one of these two similar guns. However, to import to Canada, I'd need to defeat any sound moderating device on the gun. I understand that the gun may vent air to the shroud in some fashion in order to quiet firing. But how? Easy to defeat the sound moderating features...
