Sonicore Rekkr
The Sonicore Rekkr is a modular centerfire rifle suppressor designed for higher-volume semi-automatic shooting. Thicker aluminum walls compared to the Paradox provide greater structural integrity under sustained firing cycles. Construction uses aluminum baffle modules combined with 303 stainless steel baffle inserts forming a reinforced "core." An integrated self-tightening stainless steel muzzle brake spins gas to continuously tighten the suppressor under fire. Available in DT (Direct Thread) and OB (Overbarrel) configurations; overbarrel reduces added length to the rifle and improves balance. Available in .223/5.56 (1/2×28) and .30 cal (5/8×24) variants. Made in the USA by Lyman Products.

Rekkr OB (Overbarrel) — Key Differences
The Rekkr OB uses the same construction and caliber specs as the DT but mounts over the barrel, threading on behind the muzzle. This reduces the amount of length added forward of the muzzle, improves rifle balance, and reduces gas blowback by using the space around the barrel as an expansion chamber. Recommended for AR-15 platforms where overall suppressed length is a priority.
