Which BSA air rifles will this fill probe kit work with?
This standard straight probe kit is designed to fit the vast majority of popular BSA PCP (Pre-Charged Pneumatic) air rifles. This includes the BSA R10 (all versions), Ultra (except the Ultra XL/CLX versions), Scorpion, T10, Hornet, Sportsman, High Fill, Spitfire, and Firebird.
Why does the kit include a sachet of silicone grease and spare O-rings?
The silicone grease is provided to lubricate the rubber O-rings on the probe. Regular lubrication ensures a smooth insert into your rifle's fill port and protects the rubber from wearing down or tearing. The spare Orings are included because these seals naturally wear down over time with regular charging; having spares handy avoids air leaks during a top up.
Can I connect this probe directly to my current charging setup?
Yes. The probe features a standard 1/8" BSP male thread, which is the standard UK size for airgun charging equipment. It can be screwed directly into a standard flexible fill line on your scuba cylinder/charging bottle or hand pump. Alternatively, it can be screwed into a Best Fittings Quick Coupler Plug if you use a quick-disconnect snap on system.
I have a BSA Ultra XL / CLX. Will this kit fit my rifle?
No, this specific straight probe will not fit the newer Ultra XL or CLX models. The Ultra XL requires a stepped probe design, whereas the newer CLX models (such as the Ultra CLX and R12 CLX) require a specific CLX designated fill probe. Be sure to check your exact model variant before purchasing.
