Riley K. ★★★★★ Oct 20, 2026

Just swapped out Prime's stock arms with these, and the fit is snug enough that nothing wiggles during transformation. The new shoulder pauldrons really fill out the silhouette and make him look more screen-accurate.

Christopher ★★★★★ Oct 19, 2026

The new rifle and blade attachments look way better on him than the stock ones, and they click in solidly without any wobble. If you're already a fan of this mold, this kit makes him feel complete.

I wasn't expecting the new shoulder armor to click in so satisfyingly—it really completes the robot mode silhouette. The extra blaster attachments add some great display options without making him feel bulky. This kit turned a decent figure into something I’m proud to have on my shelf.
