For those venturing into the 5.56 AK world without breaking the bank, the Pioneer Arms 556 Sporter Underfolder, particularly the BLEM (Blemished) version from retailers like Classic Firearms, presents an interesting option. Coming from a background of owning various AK platforms like a WaffenWerks 74, WASR, and NPAP, and considering the pricier alternatives such as the PSA AK-101, the Pioneer Arms offering lands in a sweet spot for budget-conscious enthusiasts. Concerns around quality control and potential issues with higher-end but inconsistently reviewed options made the Pioneer Arms 556 Sporter Underfolder BLEM, priced around $600, a compelling and seemingly safer entry point into the 5.56 AK world. Initial impressions straight out of the box suggest a surprisingly solid foundation for the price.
Initial Inspection and Build Quality
The first glance reveals attention to detail where it counts. The iron sights appear straight, with the front sight post (FSP) showing clear adjustments, suggesting a preliminary zeroing effort at the factory. The rivets, a crucial element in AK construction, look well-formed and robust, free from any immediately noticeable cosmetic flaws. Minor browning, likely surface rust from storage or transit, was present on areas like the safety selector and rail rivets but easily cleaned off. A simple application of gun-grade wax to the receiver after cleaning provides an added layer of protection, a common practice for firearm maintenance.
Internal Components and Finish
Examining the internal components, the locking lugs and hammer show slight wear marks, indicative of test firing. This is further corroborated by brass residue on the bolt face, a telltale sign of live rounds having been cycled through the action. This pre-delivery testing is a positive sign, suggesting some level of quality control before shipping.
Regarding the “BLEM” designation, the cosmetic imperfections are minimal and largely superficial. Some finish wear was observed on the bolt carrier group (BCG) where the finish readily rubbed off during cleaning, and similarly on contact points between the receiver and dust cover. However, these are purely cosmetic blemishes and do not detract from the firearm’s functionality. For a working rifle, these minor finish issues are easily overlooked and considered part of the character of a budget-friendly firearm – it’s built for performance, not for display as a safe queen.
Magazine Compatibility and Initial Considerations
Exploring magazine compatibility is crucial for any 5.56 AK. Initial tests with aftermarket 5.56 followers in surplus 5.45×39 magazines showed a very tight fit with Circle 21 magazines. However, commercial Bulgarian steel-reinforced 5.56 magazines fit much more comfortably, suggesting these might be the preferred magazine type for this platform. With limited initial 5.56 ammunition on hand, extensive live-fire testing is pending. However, the initial handling and inspection of the Pioneer Arms 556 Sporter Underfolder BLEM suggest a promising and budget-friendly entry into the 5.56 AK platform, despite minor cosmetic blemishes. Further range testing will be essential to fully evaluate its performance and reliability.
