Nielsen Slug

Nielsen Slugs .25 33.5 gr, 36.2 gr, 38.5 gr

Quality Hollow Point slugs made for air rifles.  Sold in a variety of weights

Based on testing results it seems any of the HP .250 slugs can be tuned for FX slug liners.  Some guns may like one weight better than another.  Testing so far has been with the 33.5, 36.2 and 38.5 grain.  38.5 grain is heaviest we recommend to fit the FX magazine.

At this time, we do not expect these to work in original smooth twist FX barrels but should be OK in the new Slug X barrel by FX. 

Do not buy these or any slug for standard smooth twist FX barrels.

These do work in Smooth Twist X barrel SLUG liners.

We have been looking for a night vision system that was affordable, friendly and effective.  We have found such a system in the NiteSite products.  The Viper is a simple add-on for your existing rifle.  The NiteSite system does not require you to remove your scope resight your rifle or make any changes to your current setup.  Simply attach the screen, battery pack and viewer to your scope and you are ready to shoot.

Short range scope mounted night vision system The NiteSite VIPER™ is a patented night vision system for hunting in zero light. It converts your day scope (there’s no need to remove it) into a powerful night vision system that is quick and simple to set up.

NiteSite utilizes infrared in a unique way making it more affordable, reliable and user friendly than traditional light amplification technologies.

The VIPER™ is for the hunter who wants a product without limitations. Quick and easy to fit to any day scope The true beauty of a NiteSite is that it converts any day scope (there’s no need to remove it) into a powerful night vision system that is quick and simple to set up. Indeed, from opening the carry case to hunt ready status takes just 60 seconds once you are familiar with the set up.

All NiteSites are equipped with adaptable fittings that enable mounting onto virtually any make and size of scope and there is no need to re-zero or adjust your scope in any way. Just mount the unit, switch on and you’re ready to shoot. Simple as that.

Break free of SCUBA shops, handpumps, and carbon fiber tanks forever with the Nomad 4500 PSI Portable Compressor from Air Venturi.  

Wave goodbye to scuba tanks and handpumps forever with a compressor built to go anywhere you can—the Air Venturi Nomad II.

Boasting big features in a small package, the Nomad II is a compact compressor that can be powered from any 110 or 220V outlet. But don’t feel the need to stay put! If you have a car, you have a fill source, as the Nomad can also operate from a 12V car battery—a real lifesaver for PCP gunners filling up at the range or in the field. No matter where your airgunning takes you, the Nomad II will keep you aired up and ready to shoot.

If that wasn't enough, the Nomad II has built in LED lighting on the bottom of the unit, so even when light is fading, your air supply never will. And with the addition of the built in power supply and the included travel bag, the Nomad II is easily the most portable air compressor on the market.  

Whether filling a PCP airgun from empty or just topping off, the Nomad II fills quickly and efficiently. When tested, our Nomad II was able to fill a 250cc cylinder from 0 psi to 3000 psi in as little as 9 minutes. The adjustable, automatic shut-off allows you to set the compressor to the exact fill pressure of your gun (up to 4500 psi) and the unit stops when that pressure is reached. 

The Nomad II lets PCP airgunners break free of stationary fill sources forever! Become your own mobile air powerhouse with the Air Venturi Nomad II Compressor.
