This is a new in box (never used) complete 800mm .357 cal complete tension barrel kit for new power block guns. This barrel was just released several months ago to place the 800mm barrels that came stock on M3 .357 guns. Plenty of reviews on U tube, this kit is makes the M3 power block guns extremely accurate in .357 cal with Fx hybrids.
It comes with Barrel, liner, carbon sleeve, barrel tension clamp, and probe. Paid $400.00 sell $275.00 Was going to set up another M3 in .357 but am going to do short compact instead. I can text any pics you need. No trades, buyer must pay palpal fees, shipping included. Available now. FX Impact STX Slug Tensioned Barrel Kit
