Good product. Will help save me feom cracking my lower during trigger testing without the upper.

I always keep at least two Hammer Stop blocks, it will stop a permanent crack damage in case of a dry fire when cleaning or working on you lower receivers.

JP Enterprises Hammer stop block works as advertised. Takes the impact so it prevents a cracked lower receiver.

It's simple, and works just like it should. Saw several other versions of hammer stop blocks but they were all more expensive and some looked more complicated than necessary.

A simple jig you place in the mag well from the top side to test your trigger hammer strikes and function. I used this after a new trigger installation. worked as it should, keeps your lower frame from becoming damaged.

Works as it should. Probably the best way to get a accurate trigger weight reading. Use it to test the weight and to break in the trigger. Most manufacturers recommend to break in the trigger before heading to the range.

Exactly what you need when putting together your lower and testing your hammer without damaging the lower. This is a must for every builder. Will definitely recommend this item to all my builders and friends.

This product works as intended. Though, it would be nice if it had more length so you could use it in a vice better. But the block is cheaper than having to buy a lower from hammer hitting and causing damage and still preferred over using the thumb as a stop.

This is so much faster to put in a lower receiver for trigger testing than other products I've used and seen during rifle builds. However, it is loud. Very loud. When the hammer hits this block there is a pop like a fire cracker. If you're only doing a quick function check on the FCG while assembling a lower it's not a big deal. If you're wanting to use this for extended dry fire practice you need to use hearing protection since this pop will be happening so closely to your ears. The hammers started leaving marks on this block from the first use. So far it's been struck probably 50 times and is still intact. I'm not sure that it will hold up to repetitive strikes numbering in the hundreds or thousands. I wanted something to practice dry fire on a complete lower for developing tactile muscle memory and improving trigger control. I don't think that was the intention of this product but it is excellent for lower builds.
