Standard 20-shot DPMS LR-308 magazines were furnished with the sample rifle.\u00a0 These magazines are interchangeable with SR-25 magazines, as well as Magpul 10- and 20- shot Pmag\u2019s.<!--nextpage--><\/p>\n<p><strong>Light As A Feather<\/strong><\/p>\n<p>Picking up the GII AP4 in the Gunsite classroom was almost shocking, knowing I was holding a 7.62x51mm AR type rifle.\u00a0 Contributing much to the rifle\u2019s ultra lightweight is its 1-in-254mm 406.4mm barrel.\u00a0 Unique in several ways, this already slim barrel is even slimmer forward of the gas block where it becomes truly a \u201cpensile\u201d barrel.\u00a0 At the muzzle is an equally unique combination flash hider\/muzzle brake.\u00a0 Called the Cancellation brake, this device amounts to a cylinder into which the gas temporarily is collected after leaving the muzzle.\u00a0 Restricted on the front end, the brake (and gun) is pushed forward, as some of the gas vents through eight small holes, two at 12-, 3-, 6- and 9 o\u2019clock.<\/p>\n<div id=\"attachment_28359\" style=\"width: 488px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\"

ammunition into the GII AP4 carbine on Gunsite\u2019s Shot Quad Range added only about a pound to the weapon.\u00a0 At the first shot I hesitated, as the lack of expected felt recoil was that surprising.\u00a0 Unleashing the remaining nineteen rounds rapid fire, I was just as surprised at the ease with which the carbine\u2019s sights stayed close to the target.\u00a0 Although the rifle stayed on my shoulder throughout the rapid fire, a non-slip butt would have been appreciated.<\/p>\n<p>Firing three more 20-shot magazines brought me to magazine #5, which I decided to shoot for point of aim\/point of impact.\u00a0 Since we didn\u2019t have any bullseye targets, I decided to shoot at the silver dollar size rocks in the dirt bank 25m away.\u00a0 I either hit these, causing them to disintegrate, or moved them a foot or so.\u00a0 Magazine #6 was used to make head shots on the camouflaged torso targets we were using.\u00a0 These were also done rapid fire and these twenty rounds went into abut 4 inches and a tiny bit left.\u00a0 It was time to let another on the rifle.<\/p>\n<p><strong>A GII Family<\/strong><\/p>\n<p>As I watched several others shoot this GII AP4 I was aware that I barely felt as if I\u2019d fired a rifle at all.\u00a0 After some five hundred rounds downrange, I saw no malfunctions and did not hear of any with this rifle.\u00a0 I was impressed with the package, but I soon learned that this is just one of a family of GII 7.62x51mm rifles from DPMS.<\/p>\n<div id=\"attachment_28357\" style=\"width: 488px\" class=\"wp-caption aligncenter\"><img

includes the MOE, Recon, SASS, Hunter and Bull Barrel, but the GII MOE is the only other member that is basically identical to the ultra lightweight GII AP4.\u00a0 The difference is that the GII MOE comes standard with a Magpul MOE Handguard, MOE pistol grip and an MOE butt stock.\u00a0 The GII MOE is the same weight as the AP4, but has an MSRP of $100.00 more.<br \/>\nSince the DPMS GII welcomes many aftermarket free-float handguard systems, the AP4 model might appeal to those who want to upgrade it with the buttstock, handguard and pistol grip of their choice.\u00a0 For example, I like the MOE buttstock, but would probably opt for a free-float handguard on which a wide variety of rail choices were available, and I would definitely replace the MOE pistol grip.<\/p>\n<div
