Jack10 - We made these Jack10 sets for Spike's Tactical a few years ago, and they recently sold out. The fit between upper and lower was custom, which we did at Spike's request - and means you had to buy the set. These builds were great for .308, 6.5 Creedmoor or even 338 Federal. Though the timing is uncertain, we are looking at bringing back the Jack10 as a DPMS Lower only. Time will tell!
