- AR 10 and AR 15 Versions: The AR15 version fits any 223 / 556 / 300 receiver. The AR10 one works with SR25 / M110 / DPMS pattern lower, such as Aero M5E1 (these fit Magpul LR / SR 308 / 7.62 / 6.5 mags). The Aero EPC-9 version fits the Aero EPC-9.
- Block Version: Slides into mag well from top of receiver and is locked in place by the mag catch during dryfiring / trigger tuning. To install and remove, simply press in the mag catch and slide the block in or out of the receiver.
- Front Pin Version: This version latches onto the front receiver pin and leaves the magwell open. This allows you to use a vise block which latches onto the mag catch along with the hammer stop.
- Reduce Wear: Prevents the hammer from hitting the lower receiver, saving the hammer and receiver from premature wear.

It's exactly what I needed to use while adjusting the trigger. I threw on a self adhesive rubber bumper that I had laying in my junk drawer to dampen the sound of the hammer hitting it.
The block appears to be made well, does what it supposed to do. Fits nice in the lower. Great tool to have. Shipping was quick. Price seems fair, haven’t shopped around. I would recommend this product to anyone who owns an AR. They have them for 9’s, 10’s and 15’s.
Hammer stop worked like it was supposed to.
As far as I know, this is the only dry fire block for AR-10s available anywhere. I was worried about the durability since it is 3D printed, but it is actually very durable. If you have a spare AR-10 lower laying around I would highly recommend this dry fire block.
Great product, matches the ar15/m4 quality.
i had to shave some plastic due to a rough cut on the edge, but it works great now
worked like it should on my build
Feels well made and fits inside magwell with no issues
This was perfect! I will not hesitate to order from them again! Thanks a bunch helped me with some great projects now and in the future
