Home office approved S1 L1A1 mods consisted of the following:SevenSixTwo wrote:Nobody has yet explained to me how an L1A1 conversion is legally possible. Genuinely interested in what the difference is.
New barrel without bleed, permanently de-activated gas block, deletion of the tube and piston assembly and the modification of the bolt carrier so it will not function with a piston, (very effectively carried out by carefully milling away the piston baring surface of the carrier without weakening it.
My 1962 L1 originally came from Suffolk Gun Company and is slightly different to the Anglo Custom Rifles variant.
Main difference being the method of deactivating the gas block and using their own barrels without bleed (not walther)
Anglo appear to fit and weld a rod into the gas block that protrudes out the front creating a faux gas plug.
Suffolk deac't the block (on mine anyway)The gas bleed passage is drilled out making it useless, then a rod is fed vertically through the underside of the block (Gas bleed hole) and it is welded into the pressure release hole at the top.
This very effectively deacs the block but allows the dial and Gas plug (with it's gas passage channel removed) to be retained.
All looks very nice!
I think moving forward, as more sec 5 firearms get the "SP" treatment, (I know someone who has just ordered a SP M1 Carbine) it might be prudent for all converters/builders of such firearms to agree and use an identical method of deacing components.
This would head off any potential problems with the Home office down the line. Another idea might be for Gas blocks to be deactivated and certified as such by the proof house before fitting, this may require an adjustment in the firearms law.
Looking forward and saving my pennies for a SP Garand!
