The LMT R-20 Rahe (Literally "Hail" in Estonian)[1] is an assault rifle chambered for the 5.56×45mm NATO cartridge.[2] It is specially designed and manufactured for the needs of the Estonian Defense Forces (EDF) by Lewis Machine & Tool Company (LMT).[3]

The R-20 Rahe replaced the IMI Galil and Automatkarbin 4 rifles in the EDF, the latter rifles being stored for reserve use.[4][5][6]

History

Plans were made from 2016[6] to replace the IMI Galil and the Ak 4 in Estonian service.[1][7] Among the rifles that competed included the HK416, the SIG Sauer 716 and the LMT MARS.[1] The LMT R-20 Rahe is based on LMT MARS, and is known by the manufacturer Lewis Machine Tools (LMT) as the LMT Modular Ambidextrous Rifle System (MARS) - Light (MARS-L). The New Zealand Army uses the rifle also.[6]

Representatives from LMT and the Defense Investment Center signed an agreement on July 2, 2019 to allow Estonia to purchase the new rifles under a €75 million contract.[8] The total order was 18,340 rifles.[6]

The EDF awarded the contract to LMT for the Rahe with initial deliveries made by 2019 for the assault rifles and accessories.[9] Deliveries were scheduled to be done by 2021 with an option from the company for future modernisation over the next 20 years.[9] In actuality deliveries begun in 2020 and most Rahes were delivered in 2022.[3][6]

The Rahes were fully delivered by 2023.[1] Milrem LCM and Visible Assets was chosen by LMT to serve as their Estonian partner to help with logistical support.[9] The R-20 Ls were used to replace M14 TP2s that were sent to Ukraine as military assistance.[10]

In September 2025, it was reported in the news that all of the Rahe R-20 Ls needed to be sent back to manufacturer for warranty repairs.[11] LMT covered the expenses for repairing the R-20 Ls and replacing defective gas blocks.[11]

Combat Use

The new Rahe rifles were used in Mali by the Estonian Defence Forces.[12][13]

Design

The standard barrel length of the R-20 is 14.3 in (363 mm), but a 12 in (305 mm) variant designated the R-20 S is also produced.[14][15] The rifles allow for the change of barrels.[6]

A modified trigger design allows the trigger safety to be engaged without the hammer being cocked, which is not possible on a standard AR-15 pattern rifle.[16]

The rifles were ordered with a Shot Counter Grip Module housed within the pistol grip to track parts wear and ammunition consumption with objective digital data. The accompanying reader unit can provide armorers with diagnostic maintenance warnings.[17] As the name suggest, the Shot Counter Grip Module counts the number of rounds fired by the gun.[6]
