I have been looking at the Diamondback ARs recently and see that they are pretty inexpensive relative to other AR manufacturers. I am only wanting one for plinking and target shooting for fun. Any advice or experience with this company?

I have one in 6.5 Grendel for my testing. It has functioned and performed fine for me so far.

We have one in .308, so far so good

I’d buy another

It appears to me that a DB AR would run around $450? That's expensive when compared to PSA (Palmetto State Armory). I have been buying uppers and lowers from PSA for the last 5 years and have never had an issue. Right now you can get a complete .223 upper with a 16" barrel for about $200 with free shipping and includes the bolt (#507281). Pair that with a complete lower at $130 with free shipping (#7244) and you can have a complete rifle for around $370 "out the door" after a $25 FFL transfer fee and a magazine for $15 +/-. I have built several of their units and never had an issue. You can see the reviews on their web site. I built one of their AR-47s and few months ago and love it!

I have zero experience with their AR's. However I do have experience with their DB380 pistol. Based on that I wouldn't touch their other products.

I hadn't one. Terrible. It was keyholing bullets at 25 yards. I bought it through a wholesaler that guaranteed satisfaction. Returned it.

Their pistols do look like trash and that made me hesitant about their AR’s

But honestly so far, no issues and seems to be a good budget AR

All i can say is, if you keep the trigger squeezed while next round is chambered, keep it pointed down range when you let trigger reset. Seen 2 fire on reset. Both were new and unmodified.

No issues with mine. Great shooters
