I have a gen 1 pistol that I SBR'd and LOVE the gun. I paid 1200 NIB from a guy that needed the cash.
Added an ACR stock with the Mississippi auto arms adapter (disclaimer - their anodizer SUCKS) and a Steiner P4xi. I do want some troy backups for it.
The trigger is NICE, especially when you stone it a bit. Swap the brake for a griffin to mount my Recce5. Its smoother and more fun than my ARs. 1 MOA gun easy. Accurate and fun. I may get an 806 when it comes, but I love my 805 and wouldnt trade it for anything. Its funny to watch people falling all over paying 2600 bucks for a scar16, when the 805 is just as ncie with a better trigger for half the price. And the ACR stock makes it just nasty.
Ive been thinking of getting a 14.5 barrel for mine too.
ETA - get the extended, angled and oversized CH from KNS. Best mod you will do other than the ACR stock.
