Toolcraft is my go to. After this experience I won’t stray again.
These take forever to process and ship. I contacted PSA and they told me no eta because they were coming from a third party. I placed an order with three items. Two of the three processed and shipped immediately while the bcg sat processing for several days. Fortunately this was ordered as a spare. I understand that a lot of these were sold but a little communication under the items description would go a long way. My main concern was having my order cancelled and missing out on a sale elsewhere. I tried three times to leave a review on PSAs website but they will not publish a review containing anything less than 4 stars. Bcg itself looks good. They even remembered the firing pin this time. Looks very similar to the bcg in my m&p.
These are worth grabbing a couple just to have on hand and or for future builds. I bought 2 myself.
11/5/2025 - For the same $69.99 price you can get a Toolcraft BCG with their no-questions-asked Lifetime Warranty from Arm or Ally.
