Let’s Talk About Spuhr Stock Assembly for G3,MP5,HK33/53
The Spuhr Stock Assembly for G3,MP5,HK33/53 represents a significant leap forward in ergonomics and adaptability for legacy roller-delayed firearms. Manufactured by Spuhr, a company renowned for precision engineering, this stock assembly offers a 6-position adjustable length of pull and a replaceable cheek piece, catering to diverse shooting styles and optic setups. I was drawn to this stock seeking to modernize my PTR 91, aiming for enhanced control and a more comfortable cheek weld when using optics.
The Spuhr Stock Assembly arrived well-packaged. My initial impression was one of solid construction and thoughtful design. The materials felt robust and the fit and finish were excellent. Its weight, while noticeable, seemed appropriate for a stock intended to improve stability and reduce felt recoil.
Having previously experimented with an M4-style stock adapter on my PTR 91, I found it lacking in true adjustability and cheek weld height. This ultimately led me to Spuhr. The Spuhr Stock Assembly promised a more refined and functional solution, specifically engineered for the H&K platform, unlike the more generic M4 adapter. Frankly, I was excited, but also cautiously optimistic, hoping the price tag would translate into tangible improvements on the range.
Real-World Testing: Putting Spuhr Stock Assembly for G3,MP5,HK33/53 to the Test
First Use Experience
I first tested the Spuhr Stock Assembly at my local outdoor range, mounted on my PTR 91 FR. Conditions were sunny and mild. Installation was straightforward, using the existing hardware and the included washer. The 6-position adjustability allowed me to quickly find a comfortable length of pull.
The most immediate improvement was the cheek weld. With my optic mounted on a Picatinny rail, the elevated cheek piece provided a natural and consistent eye alignment, something I struggled with previously. There were no immediate issues, and the stock felt secure and stable throughout the initial testing session.
Extended Use & Reliability
After several months of regular use, the Spuhr Stock Assembly has proven remarkably durable. There are no signs of wear and tear beyond minor cosmetic scuffs. Cleaning is simple, requiring only a quick wipe down with a damp cloth. The stock has consistently enhanced my shooting experience, offering improved control and comfort compared to the original stock.
Compared to my previous experiences with the factory stock and the M4 adapter, the Spuhr Stock Assembly is a clear winner. It truly delivers on its promise of improved ergonomics and adaptability. Felt recoil feels noticeably reduced, and the overall handling of my PTR 91 has improved significantly.
