Scott Pilkington, who owns Pilkington Competition Equip. LLC, has invented an AR-15 PCP air gun upper. The BF-17 is powered by CO2 with a gas is tank is inside the handguard.
Interestingly enough the upper is a real A2 upper that they then modify and fit the air gun parts.
We all know that one the best ways to practice in the off season is an air rifle and it certainly develops your skills, but there still numerous fine points of muscle memory and sight acquisition that cannot be the same as your Service Rifle, at least with traditional air rifles. But we decided that we could give you everything your want, the same as your target AR-15 has them already. The exact sight picture and EXACT trigger feel along with the exact feel of your buttstock weighted just the way you like it against your own cheek.
How can we do that? Half of the answer is already in your hands, your personal AR-15 lower receiver. The other half is the new BF-17 upper that houses an air rifle action made by Pilkguns. The BF-17 upper uses actual AR-15 components like an A2 upper, front sight mount, charging handle and handguards. It also has National Match ¼ minute rear sights matched to a top quality .177 Lothar Walther barrel to put your shots in the X ring where we know you have the talent to place them.
Why would you want this upper? Cheap practice with the exact same trigger pull as your 5.56mm upper. If you are used to the AR platform this would be a great competition air gun.
The cost is estimated to be between $800 and $1100. You can pre-order one for a $250 deposit. A semi-auto and A4 flattop upper version are in the works.
