Dennis Builds Another 20 Practical AR Tack-Driver

Here at AccurateShooter.com, we have promoted the “20 Practical”, a great little cartridge created by simply necking down the .223 Remington to 20 caliber. Popularized for bolt guns by Warren B (aka “Fireball”), the 20 Practical is also an excellent choice for an AR-platform varmint rifle. It offers better ballistics than a .223 Rem, with less recoil, and more velocity. Plus the 20 Practical, by all indications, appears to be an inherently accurate cartridge that “wants to shoot”. Our own AR ‘Ultimate Varminter’ project rifle, developed with Robert Whitley, was chambered as a 20 Practical. That gun shot “lights out”, demonstrating how well the little cartridge works.

Forum member ‘Dennis in VA’ recently put together his own 20 Practical AR with all-premium components. Dennis took his impressive new gun to the range yesterday, and it looks to be a tack-driver. Check out the target below, shot with Sierra 39gr BlitzKing bullets. That’s three shots in 0.375″ edge-to-edge, at 100 yards. (NOTE: regarding this H335 load, we advise to start 10% low and work up.)

Dennis got his upper from Whitley’s AR-X Enterprises. It features a heavy billet upper receiver (with side charging handle), fitted with a 24″ PacNor SS Super Match 11-twist barrel. Mounted to the upper is a +20 MOA, GS-1 Scope Rail from GG&G. Riding on top is a Nightforce 5.5-22X50 NP-R1 scope in Nightforce ultra-light rings.

The lower is equally exotic. Machined from billet by American Precision Arms, it is fitted with with a RRA LPK and a Geissele trigger. The tan, adjustable stock is a Magpul PRS model (Gen II). An Ergogrip tactical deluxe Suregrip completes the build. Dennis in VA has put together a very nice set-up to say the least. And it definitely shoots.
