Very nice rifle hand guards had a little space between them but changing them out anyways. The barrel and chamber is chrome lined. Casting Mark's on gas block are polished. Looks great can't wait for warmer weather to get to the range.

Great firearm. Mine came with a 4150 black nitride GRMOV heavy barrel. 1:7 twist. Had M4 cut but heavy barrel in front and behind cut. Nice heat shield under for end. Stayed comfortable even with barrel smokin. Feeds flawlessly with dry lube treated feed ramp. Beveled mag well nice feature. Gas block staked nicely. Put a cheap 4x32 compact scope on it and getting 2" groups at 100 yards. 500 rounds of Fiochi 55 gr brass cased through it no issues at all. Looking for a great rifle under 800 bucks this is a nice value. Hard plastic case is nice touch. Mine came cracked on the end, but would still give rifle 10 stars.

Rifle performs flawlessly. No BS warranty is a plus. ++

This is my first AR and I am very pleased. Solid construction. I've only fired about 15 rounds through it because I haven't got back up sights or optics yet, but it worked flawlessly. You CANNOT beat the CORE lifetime guarantee. I'm in the process of installing a new low pro gas block and free floating rail, flip up sights, and optics. The gun will look beautiful when complete. Very happy with my purchase and as always, great service from Bud's. For a beginner AR, I do not think you can go wrong with the price for what you get.

Alright! Another great job by Bud's! I ordered this Core 15 AR last summer using Bud's lay-away program. I made 3 payments over the course of about 60 days. When Bud's got the last payment, they immediately sent it to my FFL, Gun Supply Outlet in Springfield, MO. Too easy. If you've never purchased a firearm online, stop worrying. Bud's makes it easy, safe, and the prices can't be beat by your LGS. As far as the rifle goes, when it arrived at the FFL I noted no problems or deficiencies. The fit and finish were excellent. I quickly broke it down to give it a through exam. There was the tiniest rattle between upper and lower receiver when shaken. Functions check was good so I accepted the transfer. Took it home and gave it a good cleaning, not that it needed it. The buffer spring is really stiff. On several occasions when charging the rifle, my hand would slip off the charging handle. I have to make sure I have a good grip on it. I replaced the factory stock, pistol grip and hand guards with some aftermarket parts. At the range I quickly zeroed the rifle with about 15 rounds. I added a red dot scope and lollipopped the dot on my front sight post. It fired accurately with the optic. I was firing some cheap Wolf 55 gr steel case FMJ. On my 40th round it failed to eject. I dropped the magazine and cycled the action but the spent cartridge case remained stuck. Finally pushed it out with a brass rod. By then, it was getting late so I called it a day. Cleaned it completely when I got home. Also started stocking up on brass cased ammo. Finally, got back to the range yesterday. I used up the rest of the Wolf ammo with no issues. I fired about 120 rounds total. I was getting about a 5 inch group at 50 yards with the red dot. I attribute the poor performance to me and not the Core 15 rifle. Still, I enjoyed myself at the range! To sum up, I got a great rifle at a great price. This was my third firearm purchase from Bud's and I couldn't be more satisfied!!!

This gun is awesome. It is well made & will pump through any ammo that I feed it. I researched Core Rifles & all of their competitors. The reviews & videos on Core Rifles were all very complimentary. The warranty is incredible. The rifle was perfect, without flaw when I picked it up at the dealer & It did not disappoint me at range. If you are looking for a great rifle at a very good value on price, you can't go wrong with the Core Rifle Systems M4.

received my rifle, noticed that the upper forging was wrong.. both lower and upper are vertically misaligned do to bad craftsmanship. Hopefully core 15 lives up to their warranty claim. Haven't even fired 1 shot.. That sucks, I would expect veterans making this product to be on top of their game. Oh well what can you do, it will just take a bit longer for my rifle to be the way it's suppose to be. Other than that, I am impressed with the quality of the rifle. I'm sure I was just one of the unlucky ones that got a bad batch, cause I hear a lot of good things about core 15 products..

Core makes as good a product as any of the bigger names. They have a "No BS" warranty, and they stand by their products. Don't hesitate to buy a Core 15. It will serve you well. I have owned two now, and both rifles ran 100% out of the box. No crooked sights, no cheap materials. Just good products, built right.

    Dennis, the only difference is the above rifle has a 16" 4150 CMV Chrome Moly M4 Profile Chrome Lined Barrel while the Model #14045 has a 16" Government-profile barrel with Nitride finish. The cost difference is simply due to more of the above model being in stock than the Model #14045. Buds prices are tied to stock level and if you pay attention to any Buds firearm stock levels, you can save lots of $.

    Core used to do a 1:9 Twist on their rifles. They went to the 1:7 twist a few years ago and this UPC code is of recent manufacture. So the barrel will be stamped 1:7
