Bud's was fast and easy to shop with. However the RDB I got slam fires when driving the bolt home more than once. I sent it into KelTec for repair. They replaced nothing and said it was a gas issue. I fail to understand how sending the bolt home from lock would cause a slam fire issue due to the gas system.

Love everything about this gun. I plan to make it my truck gun. The price at Bud's was unbeatable and shipped quick.

Nice rifle, and great service from Buds. Everything went quick and smooth. Rifle performance over the first few hundred rounds has been perfect. 100 yd accuracy with a 1x dot scope is on par with nicely enhanced AR15's I've shot, let down only by my poor skills 🙂

I’m very happy with my new Keltec RDB. The trigger is much better than I expected. I’m comparing it to a Steyr AUG which much more expensive. I shot it with 5.56 62 grain without any problems. The bottom ejection left the brass in a small pile making it easy to police brass. It did leave a fair amount of residue on the rounds in the magazine but it did not adversely affect the function. I placed a 1X6 Vortex scope on the rail and a suppressor on the muzzle. Compact and reliable. Time will tell!

Buds, as always, great price, quick delivery. This Kel Tec is a pretty neat rifle. No issues or problems. 500 rounds of break in with no issues. Unlike some other reviews, I have had zero issues with steel GI magazines. Just slap and tap (like your taught)and mine seated perfectly fine. Polymer mags do seat easier though. Accurate enough, great size for vehicle carry.

very light weight, handy, looks to be well made. Plastic is a little light for handguards, but fit is perfect. Easy in and out for magazines. Really good price and quick shipping.

Great rifle. Matched it up with a monstrum 3x9 scope. Shot 500 round in the first day. Only had 1 failure to feed due to gas adjustment. Once dialed in ran great.

Shoots great I’ve had no problems with it. I love the rbd gun! Compact and low recoil.
