Have not had a chance to put the stock on. So, a blind 3 star rating.

This trigger DID NOT work on my B&T with the HK lower.

Fast shipping. Perfect fit. 3-minute installation.

absolut finest quality.

Overall it seems to be a high quality product but for the cost I feel there could have been some significant ways to make it better without a major impact on the company. First, It seems to take both hands to extend the stock to the length you need plus hold the gun. This is very disappointing. You either have to leave it the length you want all the time or be prepared for a juggling act in the moment. Secondly, they charge a small fortune for the full assembly forcing you to have to buy it with the buffer tube. The gun already has a buffer tube which seems to only be held in by a roll pin. The option should be given to the customer to swap them out and save some decent money. There is another company that makes the identical unit and gives you the choice which saves $200. Lastly, this is just a preference thing but, I would prefer folding to the left in lieu of the right. Just like fishing, the less times you have to switch hands the faster you can draw. I could hold the gun the entire time with my right and with the left, insert the mag, rack it, and unfold the stock. Again, not the worst but just preference.
