S417 Lower Receivers

Update: This batch is sold out. Thank you all for the tremendous support. Next batch will be several months from now. We will update when we have more concrete timeline. 

LIMIT 1 PER HOUSEHOLD

Our S417 and SG28 lower receivers are precision machined from original German Heckler & Koch 417 forgings and are compatible with HK 417, HK MR762, and HK G28 upper receiver groups, depending on variant.

The S417 is built to 417-spec, featuring a full-auto pocket cut and 3-position pictograms, and is compatible with HK MR762 and HK 417 uppers. The SG28 variant is configured without a full-auto pocket cut and features Safe / Semi pictograms only. It also incorporates a G28-spec rear takedown pin position, making it compatible exclusively with genuine HK G28 steel upper receivers.

For a cleaner exterior appearance and greater flexibility, the manufacturer’s information and serial number are engraved beneath the trigger guard area, allowing the end user to engrave the pertinent exterior areas as they wish.

The S417 will be offered in black and tan anodized finishes, while the SG28 will be available only in tan anodized. These receivers will be produced in limited quantities and will only be available while original forgings remain.

Tan anodizing naturally varies in shade, tone, and finish from part to part and batch to batch. Colors may range from champagne, bronze, gold, FDE, tan, brown, gray-tan, or greenish-tan, and may include darker lines, streaking, rack marks, or other cosmetic variation. These differences are cosmetic only and do not affect fit, function, strength, or performance. By purchasing, you acknowledge that color variation is normal and not eligible for refunds, exchanges, credits, or color-matching requests.
