    Sad news: Bradders.

    Haven't used it for a while, but I shot my BAR .22 at the range last night. Needless to say the rifle shot faultlessly, and was admired by others on the firing point. I thought of Mark, with a wry smile. because when he built it about four years ago I finished it in olive green furniture, and he gave me a load of sh 1t about that the time! 😁 Respect where respect is due.

    I'm another who didn't see eye to eye with Mark.....however, that didn't stop me buying one of his .22 semi AR's, and it is one of my favourite rifles 👍

    Mark I noticed that the conversion of 6 BA to imperial was 47.92 tpi, and suspected that was what made you think of it. Your edition of Machinery's Handbook is newer than mine, mine is the 14th, but lots of the data probably hasn't changed since the 1st edition in 1914! 😄 My engineering apprenticeship started at Marconi in 1969.....😮 Regards David

    Mark In a word, no. UN (Unified) threads are American, with a 60 degree flank angle, imperial measurements. We have already established that the #6-48 referred to is 0.138" diameter (3.505 mm), 48 tpi. Despite the misnomer, the British Association thread form is actually of Swiss origin, and is a metric thread form. 6BA is 0.110 diameter (2.8 mm), pitch is 0.53 mm, flank angle is 47.5 degrees.

    Matt Interestingly (and not looking for an argument on this, it is purely a nerd comment), as you say UNS, the Unified Specials, are basically anything that aren't NC, NF or NEF. However, and peculiarly, you won't find #6 - 48 on any list of UNS threads as they only start at #10-28. So, #6-48 is really a custom thread based on UN #6 diameter and thread form, rather than an actual UNS thread. It's a special, but it isn't UNS, it's a custom. The only reason I mention it is because if people go looking for a definition of 6#-48 UNS, they likely won't find it on any of the UNS thread charts . Machinery's Handbook is probably the definitive bible, and #6-48 doesn't appear on the UNS charts in my copy. Hope that makes sense 😂

    It is almost certainly a custom thread, based on UNF #6. UNF #6 is normally 40 tpi, but it is a custom at 48 tpi. OD should be 0.138", which converts to 3.505 mm 60 degree flank angle.

    Worth a read...........

    As a cleverer man than me sagely said on the subject of 'we weren't given the facts', he replied 'the stupid man gets the same vote as the wise man'.

    A different shooter

    I was teasing. When someone asks for a riflesmith recommendation, you are ALWAYS top of my suggestion list.

    That did make me giggle ?

    Gunny's Gone

    Shame, he was good fun. RIP Gunny
  11. I wrote to my MP at the time I responded to the consultation last December, and I did get a lengthy reply. Sadly, it was the inevitable political response, and he will be getting my response to that in the near future.
  12. Irrespective of the fact that MARS rifles may be a camel - a horse designed by a committee - there has been a rather devious sleight of hand operation regarding them, and this consultation: Extract from the FELWG meeting minutes of 05 February 2015: 8. NABIS Update c. Recent attacks in France Martin Parker provided an update on questions that had come out of the recent incidents in France: Action: Martin Parker to review classification with regards to the MARS rifleACPO tasked Martin Parker of NABIS to go after MARS rifles way back in Feb 2015. I believe the CCA VZ 58 rifle was run past the Home Office at the time it was introduced in 2014 and confirmed as S.1, yet in the 2017 firearms consultation there was a suggestion it should be reclassified as Section 5 - and that went back directly to that ACPO/NABIS initiative two years earlier.The significance of this is that ACPO/NPCC can try and get NABIS (who are owned by the police) to get the classification of a rifle changed from S.1 to S.5, years after the Home Office had ruled the VZ 58 S.1 compliant.The Home Office, on behalf of the government and parliament, is the arbiter of firearms law in Great Britain, not NPCC and NABIS.Once the NPCC/NABIS tail starts wagging the dog, nothing is safe any longer, irrespective of the fact that it is a gross abuse of process.Add a flawed and plainly misleading consultation process to this, and you have a complete breakdown in how the law creation, enforcement and judgement process relating to firearms in this country is carried out.
  13. Thanks. Yes, 9mm's crossed my mind, as they have been around a lot longer.
  14. Lol, nothing the matter with a MARS rifle.....as long as you are an octopus! I just was curious regarding how many CSR shooters it might affect, and their thoughts on the proposed ban
