The Recknagel Weaver Bases – Heym SR 21 (57080‑30220) are a set of precision‑machined mounting bases designed specifically for Heym SR 21 rifles. Instead of a full continuous rail, this design uses separate front and rear Weaver-style bases that attach directly to the receiver, creating stable mounting points for Weaver (and many Picatinny-compatible) rings. By spacing the bases apart instead of running a full rail length, these mounts help reduce weight, allow larger scope tube mid-sections to fit more easily, and let your scope sit lower and closer to the barrel, which can improve cheek weld and sight-in ergonomics. The bases are made from black anodised aluminium, sit approximately 5 mm above the receiver, and provide a stable, repeatable platform for optics setups.

DESCRIPTION

The front and back Picatinny/weaver bases are an alternative to a full Picatinny/weaver rail, reducing weight and creating a space between where the rings and bases attach to to the rifle. This allows for large scope mid-sections and allows your scope to sit lower and to get a closer fit to the barrel.

The ideal scope position is as close to the barrel as possible.

Black Anodised Base, Screws and Wrench

Please be aware that if you have picatinny (5.23mm) rings, they are too big to fit to weaver (4,57mm) groove spacing. The front and back weaver bases are an alternative to a full picatinny/weaver rail, reducing weight and creating a space between where the rings and bases attach to to the rifle.

This allows for large scope mid-sections and allows your scope to sit lower and to get a closer fit to the barrel. The ideal scope position is as close to the barrel as possible.

FREQUENTLY ASKED QUESTION(S)

1. What rifle are these Weaver bases for?
They’re made specifically for Heym SR 21 rifle receivers. Always confirm your rifle model before installation.

2. What kind of mounting standard do these bases use?
They use the Weaver rail standard, compatible with many Weaver and Picatinny rings (note that Picatinny rings may be slightly wider than Weaver grooves).

3. Why use two separate bases instead of one rail?
Two bases reduce weight, allow space for larger scope mid-sections, and let the scope sit lower on the rifle for better ergonomics.

4. What material are the bases made from?
They’re machined from black anodised aluminium — strong, corrosion-resistant, and lightweight.

5. How high are the bases above the receiver?
The bases sit approximately 5 mm above the receiver surface.

6. Do these include mounting hardware?
Yes — the set typically includes the bases, screws, and a wrench for installation.

7. Will these help maintain scope zero?
When correctly installed with proper torque, they provide a solid, repeatable mounting platform that supports maintaining zero.

8. Can I mount any scope rings on these?
You can mount Weaver-pattern rings directly. Picatinny rings may fit but might be slightly wide due to groove spacing differences.

9. Is this base suitable for heavy recoil calibres?
Yes — the aluminium Weaver bases provide a secure attachment, but always ensure rings and screws are installed and torqued properly for your calibre.

10. Where are these bases made?
Recknagel bases are known for German engineering and high-quality machining standards.
