This subject has been round the buoy before ............
For Bisley only - Bisley is still an official designated MOD place & the Uniforms Act Applies. The Bisley rules also say this.
For many MOD / Lanmarc ranges I think there is a condition of hire that military garb should not be worn on the premises unless serving & on duty - certainly for the Help for Hero shoots at Pirbright DPM etc was banned.
For private ranges there is no law other than the uniforms act.
There is no HO guidance either, that is BS.
Previous discussion on this resulted in Mr Mercer/NRA issuing some guidance to the effect that a smock or trousers were acceptable but that full appearance as in uniform (regardless of lack of badges that cant be seen from a distance) should not be worn. Enforcement of that is minimal, there is a bit of self management by clubs.
Am lead to believe, but dont know if its actually true? that the Camp Commandant Pirbright made official comment on a picture on the front of the NRA magazine / facebook page on people wearing camo.... some might have been his staff? off duty having fun on a Sunday no less... if so & in uniform then ... er oops.
CSR has successfully made the point & case that many military smocks jackets are designed & made to move & fire so are much more suitable vs the leather & canvas bondage jackets we TR shooters wear. I believe thats in the CSR hand book now. & NB the NRA rule about not firing more than 14 shots in a string has been quietly dropped too so 25rnd ruger mags are ok, however indiscriminate fire inst allowed.
Page 107 of the Bisley Handbook says:
Dress and Equipment
397 Hearing protection is mandatory during all live firing.
398 The wearing of gloves is permitted during all matches.
106 RANGE OPERATING PROCEDURES
Clothing
399 Any jacket or combination of clothing designed or intended to provide support to the body is not permitted. Padding or soft material for the purposes of protection or comfort may be used on the shoulder, on the elbows and on the
upper arm.
This padding may be affixed internally or externally to a loose fitting jacket of any design or style having a lightweight, single thickness outer, provided that the combination of the padding and jacket does not provide support to the upper body. Strap-on elbow and knee pads may be worn.
400 Modern medium-weight and heavyweight purpose-designed canvas, leather or synthetic shooting jackets are prohibited. Similarly, the wearing of excessive layers of clothing, with the purpose of restricting upper body movement (thereby providing support), is also prohibited. The wearing of the UK military issue sniper smock is allowed. Sling keepers are allowed.
401 During inclement weather waterproof clothing may be worn in all matches by firers and team officials (if any).
Other organisations may have different rules.
Regardless of the right to wear whatever one wants, wherever one goes, carry carry what ever, go shopping in Asda with an AR on your back in a DPM coat, the image of portly shooters in camo on ranges attracts a fair bit of 'banter' & criticism in some circles (& not just the 'straw hat shooting clubs' ;-) ) & the image created by it & one of paramilitary style shooting is not seen as innocent & positive even vs the more strange, even quaint TR bondage gear worn by 3P/air rifle & target rifle shooters.... by people, like parents of scouts & kids coming shooting.
So when the Daily Fail run a story that one day & they will do, about this we will be having the Image debate in public & will loose the argument to prejudice from public/voter even dare i say a politician bandwagoning for an increase in share of their vote.
