Ross Ranger Rifle, as mentined in a previous Posting.
The rifle is very simply a M10 with a shorter barrel, fitted with the standard front sight, but without "Hood "or "Ears"
The Rear Bridge (which was used for the Flip-up sights in both standard Military and also for the simple "Ranger" sights, is instead completely "Flat", and seems made that way oat the factory; A simple rear sight is dovetailed into the barrel ( Looks like a short renage type sight, with Windage adjustment as well, set for 25, 50, 100 and 200 etc yards.
Stock is walnut, and well figured. rear sling swivel is typical Ross Type, and front swivel screws through forearm into Barrel Block on sleeve. Rifle Blued throughout ( from "uncovered" parts where sights , barrel block, etc were.
Yesterday I did "Ross Rifle 101 "... stripped it down to the last screw, Pin and parts...The only thing to esacape dismantling were the Magazine, the Bolt's safety catch (captive plunger spring) and the Lock screw, and pillar in the receiver-barrel thread area. Everything else cam apart, with due care and attention not to lose any of the smaller parts.
It looked as if the rifle had not been cleaned in over 50 years( yes, the Rifling was quite worn---looked almost "Metford" like!!!)
If anyone wanted to make a complicated Rifle, the Ross surely wins first prize, at an engineering level. Some of the assemblies are devilish in their conception...the Bolt latch detent plunger, for one, and the Ejector Retaining Pin for another....not to mentiuon the "NOT GOOF PROOF" Bolt. Thank goodness I had another Ross Bolt side by side to compare when re-assembling the Sporter Bolt...to prevent the "Unlocked Bolt" Syndrome.
Anyway, after 4 hours of cleaning, oiling, and fiddling to get everything back together without losing, breaking or otherwise abusing any pieces, I had the rifle back to shooting condition, except for the rear sight (still in kersoene to loosen the threads) and the Barrel block off to work out the thread of the screw hole ( Looks like 3/16 UNF, but could be an American Number screw size... for the front sling swivel and forearm lockup to barrel.
More when I clean the Military M10 (Mark II, ex Chilean Navy, "ex HMS Canada" which, by the way, shoots a dream with Aussie 1950s Mil ammo.
