MR-TLR1 - Streamlight-style rail adapter for MantisX

MR-TLR1 - Streamlight-style rail adapter for MantisX #

The Mantis X10 training device provides excellent feedback on the different phases of your draw, presentation, and trigger pull. But your holster may not support attaching the MantisX hardware.

Our MR-TLR1 adapter enables you to train your draw with MantisX hardware using the light-bearing holster you carry every day.

For dry fire ONLY.

Order at the croix.systems shop


Attach your MantisX device while retaining the ability to draw from holsters with Streamlight TLR-1 compatibility.

Adapter is secured with a metric M3 bolt and installed with a 2.5mm drive hex key or 3/32 inch Allen wrench.

Customizable adapters #

Features removable adapters for M1913, Glock-compatible rails, and Ruger LCR. We also offer a rail-only adapter for the Ruger LCR.

For LCR, the adapter locks into the ejector rod channel under the barrel. Releasing the cylinder for reloading practice is not available.

Holster compatibility #

Tested and compatible with the PHLster Floodlight IWB and OWB TLR-1 holsters, and with Safariland light-bearing M3X holsters. If you have a different style of TLR-1 compatible holster and would like to test this adapter, please contact us at beta at croix dot systems.
