- 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.

- Original, Innovative Design: 2200+ products designed and 3D printed in the heart of America in St Louis, Missouri by Hammy3DPrints.



MATERIAL: 3D printed using PLA+ filament. Note that this filament is not a high-temp filament rated for use inside vehicles left in direct sunlight during summer. If you require a higher-temp filament please contact me.

INSTALLATION: Slide in from top of magwell while pressing the mag catch in. There is a slot in the block that the mag catch fits into to lock this device in place.

WARRANTY: If this item breaks I will make any design adjustments, if needed, and send a replacement for free.

Made in USA.

Please note that the products may have slight imperfections as 3D Printing is rarely perfect. The exact product you receive may also slightly vary from the product photos as I iterate and improve upon designs based on user feedback.

3d Hammer Stop

The Hammer Stop fits perfect and the orange color is great.

I think everybody needs one of these!

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.

Hammy3DPrints Dry Fire Hammer Block

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.

I like it

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.

Every product I have purchased from here has exceeded any expectations I've had. I keep coming back because everything is quality made, strong and durable and the customer service is always great. I can't stand when things are unorganized or out of place and this allows you to store and display the weapons and accessories that you've spent the most on. I sure as hell wouldn't hang a $3000 rifle on the wall with command strips or duct tape, but I would (and do) hang my rifles with mounts made by this seller and never once had an issue or concern about them not holding up. You can't beat the prices or quality here!! I highly recommend you give them a try. You won't be disappointed!!

I am building a few AR15 9mm pistols. Do you make a dry fire block hammer stop for a 9mm glock size magwell. The AR15 9mm uses a glock 9mm magazine.

hammy3dprints

Hello,

I don't make one at this time. I'm not sure if there is standardization between different 9mm lower receivers. Can you email me what brand lower receiver you have? I've had a request for an EPC-9 one before.

Thank you,
Matthew / Hammy
