Mast Spike Kit for Explorer POTA 20 & POTA 33

Should you have questions, I made a FAQ video - youtu.be/EDFYLqpytqA

❌ NOT Compatible with LD6 or POTA 33H Masts

This version will not work with the Lil Dude 6 (LD6) or POTA 33H or 33B masts.
If you have an LD6, check out the Dude Spike 2.0 in my other listings.

➡️ According to community feedback, this POTA 20 spike is compatible with:

POTA 20

SOTABeams Tactical 6
Carbon 6
(Still unsure? I may not be of help, but I can try)

If You want the Pota 33 (NOT THE H MODEL) spike kit, select POTA 33 OTHERWISE, select Stainless - 3/8-24 or Stainless M10 for the POTA 20 kit. If the POTA 33 kit is sold out, please do not buy the POTA 20 kit.

The POTA 33 kit has been tested by multiple people and the reports are that it fits with about 1mm of a a gap between the spike kit and the mast. The POTA 33 kit is currently offered ONLY in 3/8-24
