Recently purchased my first AR. I got a smoking deal on a DPMS Sportical for coyote and general varmint hunting here in the mountains of southwest Virginia. I don't plan on any shots further than 300 yards. I have installed a Mega-Arms trigger and will be putting an Alexander Arms G10 Composite free float handguard in the coming weeks. First day at the range proved promising at 100yds. After the first 20 rounds of shoot and clean with inexpensive factory fodder my first 3 shot group turned in at a tad over .500 inch with some of a buddies handloads. Any views on what field practical upgrades I should look at acquiring and good handloads.
