Perform perfectly

Good - requires tuning

Review by LWL on 6/2/2020

Overall good. Requires tuning/ sanding of mating surfaces on the magazine to ensure a smooth transition for the follower from extension to the magazine tube.

Mega round

Works great. Remember to perform trimming

Review by Randy C. on 7/25/2019

Paired this with ETS long mag and it is working well. I really like the removable base plate which allows easy cleaning of mag and spring without removing the entire extension and having to bend the spring as with some other brands.

It works

I have had zero problems with this extension and shoots forever.
