Review
The factory Sub2K springs suck. But these MCarbo springs make the trigger pull and operation so much smoother. It’s brings an ultra crisp trigger pull (I also have the MCarbo trigger too). Not to mention, the MCarbo installation video makes installation a breeze.
Customer brought this in for me to install made a big difference in the performance of his sub 2000 tighter groups are always a plus
These springs installed perfectly with a great assist of the videos.
The spring kit was easy to install, especially with the instruction video. The kit really cleaned up the trigger pull and reduced it from 9-10 lbs. to 4.5 lbs. The aluminum trigger is also an improvement. Kudos to MCARBO for a great product and support.
I am very pleased with this modification, as together with me polishing sear and hammer friction areas, it reduced the trigger force considerably, improving my accuracy quite a bit.
nice reduction on trigger weight of Sub 2000. Using the video on installation made the job easy.
Best upgrade for the Sub2000. Combined with the flat faced trigger, game changer!
It was a Little tricky to install. I took my time and it works great.
Great upgrades to my 1st gen Sub 2000!! I ordered the Trigger Spring Kit, Target Trigger and Double Finger Charging Handle. MCARBOs how-to videos were very helpful for parts installation. They use a Gen 2 but with a little intuition it was easy enough on my Gen 1. Trigger pull is so much lighter with new springs, new trigger feels like a real trigger and the longer charging handle gives more leverage with less strain and pain on the single finger. Customer service was excellent in getting info to me with a back order issue. The folks at MCARBO are doing a fantastic job to get and keep our business!!
I received item quickly and install was painless sine iwatch the video previously . I polish ed the mating surfaces lightly with 100 grit wet/dry sandpaper and could ot be happier. Trigger pull was light and crisp.
Ordering was easy, shipping was fast, installation was per the video, parts fit nicely and performance was enhanced. I highly recommend this vendor.
I installed the spring kit and target trigger and with a little polishing my trigger now breaks at 4.9 lbs every time. It makes a huge difference and I should have done it sooner. Thanks for making a great and needed product.
Love the new trigger feel after installing the spring kit in addition to the flat trigger kit, trigger bar and stainless hammer bushing. Quality products that exceeded my expectations!
Another must have upgrade. Added the trigger bar as well. Got rid of that 10 lb trigger pull with all of that take up. Now the trigger is much smoother, far less take up, and great reset. Who needs a bump stock anyway, thanks Pres Trump and the NRA.
As a first time sub 2000 owner i didnt expect much out of a $499 rifle but i really enjoyed shooting it the first time out. The first thing i noticed was how HEAVY and "cheap" the trigger felt. We put about 200 rounds without hiccups but i noticed that when it got hot the trigger pull became heavier and mushy to the point where i couldnt feel the clicking. On a hot day at the range the rifle failed to even function because the trigger began to bend and malfunction. I couldnt shoot a single round out of it. Eventually i searched and found this trigger spring kit on the internet and decided to give it a go. The install was super easy since i had torn it down several times to try and find the issue with the trigger. Since i could see the stock trigger bending under light pressure i decided to also get an aluminum trigger. The combo of an aluminum trigger and MCARBO spring kit really did wonders for this rifle. I left the rifle in a hot car for a few hours and fired it at the range right afterwards and i got a clean crisp light trigger pull. I really think this is one of the best upgrades for a Sub 2000
Took my trigger press to 4lbs. Very easy to install with Chris' awesome video. I am very pleased. Thank you Mcarbo.
