CORE 15 Rifle Review

Confirmed, my Core15 basic gas, is commercial tube.

Awesome guys. Just to clarify, the scope is a 1.5 MOA dot, not a 5.

Sorry for the late review. Life's been busy. None the less, here's some results from the gas (DI) upper. I should be back to the range shortly to play around with some more reloads. I'm not really liking the results with some of the factory ammo, especially the cheaper stuff, but some of the reloads look quite promising. Was slightly breezy the day I shot these.

All these grouped were shot with a Vortex Diamondback 4-12x40 scope.

Post #52 were all those groups shot with the piston upper? Theres a few good groups in there.

Yes. All previous posts were with the piston upper.

Here's more results with various reloads, and one factory group with Zombie Max. All shot with the GAS upper, 1:7 twist.

I know I'm bringing this one back from the dead. Do you still own the rifle? Did you keep the piston upper or did you ever get the rifle entirely replaced as promised?

Glad to ser some more Core15 love

Here is mine. Owned it since 2014, 1000s of rounds of all kind, not a single malfunction. Now its my "long range" setup

I have a core15, gas upper. Love this rifle. Great quality so far. I have had mine for a couple years. My wife loves it.

I kept the piston upper. Had a problem where the piston bent once, but was replaced with no issues. This is my primary 3 gun rifle, and other than the bent piston, has worked flawlessly. Only mods to the rifle are a Gisselle sde trigger, spikes tactical buffer, and a michelak brake. Otherwise it's as delivered. I've taken the scope off and shoot open. Zero on the supplied magpul sights hasn't changed a bit. I won't be doing any more load testing until I get a better scope. I feel the scope I was using is limiting the accuracy of this rifle.

i also had difficult 'first AR' decision. my only experience shooting AR was norinco and colt iur both in 556. loved the colt as it was very accurate, but it weighs just short of a school bus...heavy, and pricey.

so i went with the NEA PDW 7.5" in 769!!!

short. light. concealable in 5.11 backpack. lifetime warranty. low recoil. accurate. $0.18 a cartridge to shoot. great customer service. takes beowulf mags for 14 rounds of 769 each mag. reliable. reasonable price. AWESOME!!!!!!

Just out of curiousity what benefit does it serve that your rifle is easily concealable in a 5.11 backpack?

it just carries inside my backpack so i don't have to lug around a huge rifle bag along with my backpack to the range. its convenient is what i meant.
