Frequently Asked Questions

What is the Turner Semiauto SMLE Conversion?

The Turner Semiauto SMLE Conversion is a rare 1941 prototype rifle that converted the bolt-action Short Magazine Lee-Enfield (SMLE) into a semi-automatic firearm. It was developed by Russell Turner and tested in Canadian military trials against the M1 Garand.

What made the Turner Semiauto SMLE Conversion perform well in cold weather?

Its superior performance in extreme cold (-25°F) compared to the M1 Garand was attributed to its innovative 3-port adjustable gas system, which allowed for regulation of the cycling action based on environmental conditions.

What is unique about the Turner Semiauto SMLE Conversion's bolt mechanism?

It features a side-locking tipping bolt, a relatively rare system. As the bolt cycles, the bolt head tips to engage locking recesses within the receiver, ensuring a strong lock-up.

How does the Turner Semiauto SMLE Conversion handle safety?

It incorporates a clever out-of-battery safety design. The hammer is designed to 'straddle' the firing pin, meaning it cannot strike the pin unless the bolt is fully locked into the receiver, preventing accidental discharge.
