No sleep for those with chigger-itches. Up at 5 AM and on my range beside the house at 7.
1st up was a preliminary test of the new rimfire conversion kit for an AR from DPMS. This is a complete upper that will fit any AR 15 style lower. I installed it on my Remington R 15 .450 Bushmaster lower, mounted a Sightron 4 – 14X scope on a Weaver rail and started shooting. First I ran 50 rounds of Remington Golden Bullet ammo through the gun to test functioning. One empty case got caught in the action. I then tested five loads for accuracy at 50 yards. The rimfire upper passed the preliminary test so it looks like a full review is in order. These uppers will soon be available from DPMS with a suspected MSRP well under $ 500.00.
50 YARD RESULTS
Remington Golden Bullet 1.45”
Remington Match Target 1.27”
Winchester Power Point 1.51”
Federal 40 gr. Copper Solid 1.20”
CCI Stinger 1.03”
Next up was the Barrett REC 7 in 5.56. I had previously zeroed this carbine with a Vortex SF BR HUNT using a 2X doubler. During that test I ran 100 rounds through the gun conducting various drills. There were no malfunctions. This morning I tested four different loads at 100 yards using the red dot with the 2X attachment. The largest of the 12 groups fired measured just under two inches. The smallest group fired was with Black Hills 69 grain Matchking and measured .72. Look for a comprehensive review of the piston-driven REC 7 in an upcoming issue of Guns & Weapons for Law Enforcement.
Now, I must go find the bottle of clear fingernail polish and paint my red bumps…More to come.
