Hey guys, this is Brian from Hartatac.com. We are very close to receiving our first production run of the HartBlock, a -20 limiter for Gen3 30-round PMAGs.

If you want to get a great deal on the first batch, you need to visit our IndieGoGo crowdsourced fundraiser.


We should have them in two weeks. They are made from glass-filled nylon (similar to PMAGs) and will outlast the unconstitutional laws that require them in the first place.

Intro pricing through the fundraiser:
3 for $12
8 for $30
30 for $100

Please share our link with anyone who might be interested. We hope to bring many more quality limiters your way with aggressive pricing and premium materials.

Here's our YouTube video showing it in action

Hey Brian, your blocks look very similar to Magblock's existing design. Was this intentional?

It is similar to Magblock and Magpul's internal limiters. Any limiter is going to look similar to others on the market because of the tolerances required. The physical appearance was determined by our engineers to provide the best strength for the product as well as manufacturing simplicity. We are offering one made of glass-filled nylon that is extremely durable.

Expanded marketplaces and product variety are always a win-win for the consumer.
