CURRENTLY OUT OF STOCK AND NOT AVAILABLE FOR PRE-ORDER!
Like all direct impingement operated rifles of this style, this rifle works best with BTHP, polymer tipped and FMJ bullets and does NOT work well with lead tipped, all lead, round nose or other soft point bullets. It also requires generous lubrication of the bolt assembly at all times. This is critical for the first 500 rounds as the moving parts break in.
These rifles have a MATCH GRADE barrel and chamber. The use of off-shore surplus or corrosive ammo is not recommended. We have found that match grade factory ammo or handloads will produce the best accuracy. Decent domestically manufactured bulk ammo will not harm the rifle.
The base model upper receiver chambered in 223 Wylde is $1700.00. This does not include a bolt, carrier or mag.
The base model upper receiver chambered in 6.5 Grendel is $2200. This includes a complete bolt and carrier assembly made by JP Enterprise and one 6.5 Grendel mag.
There are a large number of upgrades available at additional cost.
