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.

My first time buying a rifle/gun online and from Bud's. I can say It was a bit nervous, although Buds made me feel reassured. I ordered this Core-15 rifle late Monday night (11:40 pm est.) and I came in early that Friday! Much sooner than I expected...:) I was also able to track the shipment each step of the way. Mine is a 1:9 twist barrel, M16 bolt group, hard case etc.. I was very happy and can't wait to shoot it! Buds saved me $150 buying from my local Gun dealer. My advice to new buyers check out the gun you want to buy locally before you buy online. This is what I did, I will be a returning customer at Bud's they had the best price on the net and local!

I am very pleased with this rifle, it has a very nice finish and for the price can't be beat with the best warranty in the business. Took it to the range last weekend and put a 100 rounds down range with no FTF with cheap ammo. I noticed a little bit of play between the lower and upper but this is very common with AR platform rifles just as my rifle in the U.S. Marine Corps. The rifle came to my FFL in a alright plastic hard case with one Magpul magazine and breech lock. Thanks Buds!
