SIERRA SD Suppressor

Rated 5.00 out of 5 based on 3 customer ratings
(3 customer reviews)


The SIERRA SD suppressor was designed for the .338 Lapua cartridge and features the 2 point contact along with the 2 stage high and low pressure section, similar to the BRAVO SD. This suppressor is ideal for .338 Norma, .338 Edge and .338-.378. The 11.625 inch over the barrel suppressor only increases barrel length by 9.625 inches.
All models have 100% repeatability whether the suppressor is timed to the weapon or not. If the shooter would like to minimize the horizontal point of impact shift when shooting suppressed, the Elite Iron name should be top dead center when suppressor is installed on weapon. (Plus or minus 10 degrees). If this is not the case, the included shims will allow the brake to be installed properly.

Included with each suppressor purchased you will receive a free Elite Iron suppressor wrap used for optical mirage mitigation and heat issues.
Please include the following dealer contact information. Phone number, Email address and Shipping address where suppressor will be shipped for transfer. This information can be entered in the order notes box on the checkout screen or used as shipping address.
