The barrel length on this gun is advertised as 16.1”, however, I measured mine from the bolt face (on a closed bolt) to the end of the threaded muzzle (with muzzle device removed), and it actually measures 17-1/4”. How is Ruger measuring these?
That's not what the ATF says, is it? I thought it was with a rod down the bore, so from the bolt face to the muzzle. Did they change?Typically, barrel length will be measured from the end of the tenon to the muzzle.

Typically, barrel length will be measured from the end of the tenon to the muzzle. The bolt face is recessed and has some clearance from the tenon in the Ruger, so it ends up an extra length. A lot of folks measure from the gas port hole in the action, since this should mark the interstice between the bolt head and the barrel tenon. That difference doesn’t typically end up ~3/4”, however.
But…
Is yours a really early model? I remember the early 16.5” barrels being reported at 17.25”, and the early 18” models at 18.7”. I haven’t heard of any contemporary manufacture models with incorrect lengths, but I suppose it was possible before, maybe just as easy to occur now for whatever was the reason it happened before.

But 1/4” ain’t 3/4”, and it’s a known topic for EARLY GSR’s - I haven’t heard of any recent manufacture scouts with over length barrels, but 17.25” barrels on the claimed 16” GSR’s was a thing early on.
Interesting about the early models, I never knew that. Are there any other differences or issues associated with early GSRs?
The first few years of the “16 inch” Ruger GSRs were listed as having 16.5” barrels and they actually measure 17.25”.
Once Ruger came out with the polymer stocked models, the barrels got closer to a true 16” and the spec sheet got changed to 16.1”.
I have one of the early 16.5” GSRs with a 17.25” barrel.
Speaking of the 18 inch models, the early spec sheets claimed 18.0 even though they too were 3/4” longer. Last time I checked, Ruger stuck with the 18.75” length the entire run of the “18 inchers”.
Very interesting, thanks for the info. And all this time I thought I was hunting with a 16” barrel…
This is good news because I'm considering having the barrel cut a bit and rethreaded in order to work a little better with a suppressor. With a 17.25” barrel I have plenty of length before flirting with the 16” rule.
My plan, if it’s feasible, is to cut about 3/4” off, and rethread, utilizing the shoulder that the rear of the front sight is currently sitting against as the suppressor shoulder. We’ll see.Hmmm. If you do it, post a pic of the results.
Does the Ruger Gunsite use a proprietary magazine?
Could you tell me more about AICS magazines? From what I read, they are different from M14 and AR10 magazines. What other guns use them?AICS Patterned
