Review
Only complaint is that the gun took forever to take apart and put back together but fortunately they provided a installation video to help me with that. A little bit of sponginess before a crisp break. Better than any tavor or aug trigger for sure. cant wait to try doing some rapid fire with it. 10/10 must have for the RDB
Trigger pull of the stock RDB was horrible. This upgrade is so cheap with a huge reward! I didn't think it would make THIS much difference but I am pleasantly surprised.
Really liked the trigger. M-Carbo has a very comprehensive installation video on YouTube. I put a review of it up on Cluster Duck Outdoors YouTube channel.
Was very happy to find you guys had this product and after seeing that you had a video walk through on installing, I ordered right away . Delivery was prompt and follow up was promt by email making sure I had access to video, printed walk through or contact number to answer any questions. I've installed lots of trigger sets on different rifles and pistols, but this platform was all new to me so the video was just what I needed.. Install was a breeze, and it did in fact lessen the trigger pull as stated Very satisfied with product and support. Thanks
Watched video and made install very easy. Upgrade spring kit works great!
Great installation video! It took me a moment to install the spring, but thanks to the guidance from the video everything worked out perfectly. It was fun actually to tinker with my rifle! The trigger is definitely lighter.
I have yet to install the spring, however I'm excited to get it in there. It shipped quickly and for a few bucks why not? I'll write another review in the future when I've had a chance to use it for a few rounds.
I took the RDB to a two gunsmiths and neither could get the RDB apart. Maybe it is just mine. The kit arrived fast and looked great, but I can't speak on it unfortunately. (I really wanted it too.) I'll assume it was perfect
Unreal. Did exactly as video said. Now when you cock the hammer while on safe, it releases the hammer and FIRES WHEN YOU TURN SAFETY OFF. WTH? Ruined the gun.
After shooting both my RDB and my AR with a drop in trigger, I realized how bad the RDB trigger is. This spring makes the stock trigger much better. FYI, I did not remove the bolt stop buttons. You can pry the halves apart enough to replace the spring without completely separating them. I cannot wait for M*CARBO to sell an entire trigger assembly! 😉
I was skeptical that the RDB trigger could be improved so much just by replacing the spring, however watching the installation video before purchasing had me very interested. After seeing the price, I was sold! This spring upgrade blew me away! You guys really need to create more parts. Maybe a new trigger, foregrip, and magazine release!? Keep up the great work!
This spring gave a noticeable improvement to RDB's trigger pull. Awesome improvement for a low price. Installation instructions video was very informative. Only thing in the video I did not see was how mag release button was removed. It did not cause a problem, it was easy to figure out. Still trigger-pull is not perfect because of long take-up, which cannot be fixed by spring replacement. Would be nice to find some sort of gizmo to make take-up shorter. Perhaps the trigger bar itself could be replaced by a different one with a smaller 'hole' for sear engagement.
Bullpup triggers generally suck. But sometimes you have to give a little to get a little. Exception is the RDB trigger which does not SUCK to begin with. Mine cracked at 4lbs 13ozs stock. Not too shabby...by any standards. Then someone, Chris, says “Nope, that still sucks”. And delivers a trigger spring that dropped my RDB pull down to 2lbs 8ozs. On a freaking bullpup! My follow up shots were already decent with my YHM Slant compensator. Now they are twice as fast with a $13 spring! Thirteen freaking dollars! Thanks Chris for doing something that others try to lure us into thinking costs $300 with a plethora of parts. You deliver a simple solution at 5% of the cost. Charlie Mike Brother!
In the world of aftermarket support, it's refreshing to utilize parts that actually work better than advertised. The M*CARBO Kel-Tec RDB Trigger Spring Kit arrived in short order, installed without issue (utilize the excellent an comprehensive instructional video) and proved a superior trigger pull experience. I can't recommend it enough and I'll absolutely look to M*CARBO for their other firearms accessories in the future. Eddie Massaro Owner @massaroholsterworks
The people at mcarbo sent me the spring but the post office lost it. I called mcarbo and they sent me another one ASAP with no questions asked. Received the spring and installed it in about 35 minutes with their YouTube instructions. It was easy. I used it in a run and gun event the very next day and it worked great! Thanks
Ordered this spring and shipping did take some time but give the way shipping has been lately all companies are having issues. Once it arrived i immediately started the install. The video is amazing and install went smooth. I went to my buddies range and WOW! Absolutely amazing! I recommend this to everyone who has the RDB
