Probable NZSRA LMT Caused Rule Update
I'm not a spokesperson for NZSRA, I got this from there FaceBook page - https://www.facebook.com/New-Zealand...5064977357449/
"Initial Specifications for NZSRA compliant LMT MARS rifle.
NZSRA LMT MARS rifle and Clone Specifications.
Interim Specification, 21st August 2016.
Please note: As the NZSRA are yet to fully understand every aspect of the “yet to be issued” LMT MARS rifle these specifications are published based on repeated requests from NZSRA members. As at August 2016 there are some specifications that are not fully resolved to the NZSRA committees’ satisfaction and are noted. Should the specification change the NZSRA holds no responsibility for any costs or troubles incurred in complying with any revised specifications. Please also note the NZSRA have inspected a MARS rifle and the specifications listed here are based on a physical inspection of said rifle. We are also reliably informed that NZDF personnel are unlikely to have the rifle for use at the 2017 NZSRA National Matches at Easter.
Upper Receiver: To be of a monolithic design where a significant part of the hand guard assembly is homogenous with the upper receiver. The Upper Receiver shall have the standard A4 features including a dust cover and forward assist. The hand guard section shall be no longer than 9.5 inches and shall sit behind the gas block on a Mid Length gas system barrel. Note: Uppers made by manufacturers other than LMT are acceptable as long as they meet these specifications. The upper should have at a minimum a Picatinny rail on the top section of the hand guard. The Bolt assembly can be an LMT enhanced bolt or a standard AR15 bolt assembly.
Lower Receiver: Lower receiver to be based on standard AR15 Lower receiver with the following exceptions. The Magazine well entrance may have an enlarged bevel. The trigger guard may be of the larger “winter style”. The trigger should be of the standard AR15 type with a minimum break of 5.5 pounds. (Please see notes on triggers). The controls may be of an ambidextrous type but this is not compulsory. (Please see notes on ambidextrous controls).
Barrel: The Barrel must be no longer than 16 inches and will use a mid length gas system. The barrel will have a diameter under the hand guards of no more than .730 inch and the gas block diameter must be .75 of an inch. The barrel forward of the gas block area may be no larger than .740 inch. The barrel must be made from Chrome-Moly steel and may be chrome lined. It may have a Parkerised, black oxide or QPQ (Salt Bath Nitro carburised, Melonite, Tenifer etc) finish. The barrel must safely chamber 5.56 NATO ammunition. The gas block may be attached with a single pin, clamped on or held on with set screws. The Muzzle may be fitted with a Surefire WAR Comp or an A2 flash suppressor.
Ambidextrous controls: If the competitor chooses to they can fit ambidextrous controls to the rifle. This includes; the charging handle, the bolt release, the magazine release and the safety selector. Note: as there are a number of variations here the fall back position will be what a genuine LMT MARS rifle uses, anything that is larger, longer or offers an advantage over the parts fitted to the MARS rifle will not be accepted. The Ambidextrous controls should be no larger, longer or prouder than the controls on the other side of the rifle. Until such time as the NZSRA are able to fully evaluate the “Issued MARS rifle” we would offer the following advice: If you do not need ambidextrous controls because you are a right hand shooter it may be best to wait until the “as issued” rifle is fully examined and the specific parts or variants thereof are approved. If you fit a set of ambidextrous controls and these are latterly rejected by the NZSRA we will refer you to this document.
Trigger: As of August 2016 the NZSRA are unable to determine the exact type of trigger to be fitted to the MARS rifle, we have a request into the NZDF and as soon as this is established the NZSRA will amend the specification. As such the fall back position will be the standard AR15 trigger, with a pull weight of no less than 5.5lbs.
Butt-stock: The Rifle must be fitted with a collapsible stock assembly. The butt stock itself should be either a B5 Systems Enhanced SOPMOD Stock or a Mil-Spec M4 type butt-stock.
Grip: The Grip may be an Ergo Grip #4009 made by Ergo Grip/Falcon Industries. An A2 grip may also be used.
Notes: The specifications noted here apply only to the LMT MARS rifle and clones thereof only. No specification here is transferrable to standard AR15 rifles as used for Service Rifle Competition. The specification for the Standard AR15 rifle is listed separately and may be updated from time to time to reflect the evolution of service match code. Under no circumstances should a competitor mix and match specifications from the LMT spec to the standard AR15 spec as this may lead to a rifle being declared out of spec and designated an open class rifle. As always if you are unsure then ask (At least 2 weeks before the event). If you choose not to ask and assume it will be ok then at scrutineering you will be referred to this document."
Time to start collecting parts for yet another AR, even though I don't see a build to this spec or this spec with any changes that are likely to happen as actually being a competitive over a 20" HBar build
