Talk:M40 rifle

Scope
Reportedly, the USMC will replace the S&B with a Premier Heritage 3-15x50 scope (PH no longer makes reticles for S&B). This was an approved engineering change, not a new contract.

Hathcock
Hathcock used a Winchester Model 70, not a Remington 700 (or M40A1).198.45.3.253 21:06, 7 September 2005 (UTC) Philo C.

Perhaps the whole sentence on Hathcock should be taken out?

Great work on the article! Looks extremely clean, probably best short weapon article here! ~Tin

Article edited to include new S&B scope. Source: http://www.defenseindustrydaily.com/2005/09/usmc-snipers-to-replace-failing-scopes/index.php 198.45.3.253 14:59, 2 November 2005 (UTC) Philo C.

The M40A3 actually has a inch longer barrel than the M40A1. The M40A3 measures its barrel length from the lug, so according to the old way of measuring barrel length, it is actually 25" (and has a better muzzle velocity). 198.45.3.253 15:12, 2 November 2005 (UTC) Philo C.

The picture for the sniper rifle that was changed from a M40 to M24 does not show up, but the USMC uses the M40 and the army the M24. Please check photo. (M24 uses HS precision adjustable stock, which is easily identified) 198.45.3.253 12:42, 25 June 2006 (UTC) Philo C.

The gun in that picture looks like a K-mart replica. Is that the best picture availible? How about something with (at least) camo paint on it to make it LOOK like its a military gun. Looks half plastic.... Ghostalker

Carlos Hathcock played an important role in the design of the M-40 and deserves a mention in this article.--Dog777 (talk) 20:25, 14 December 2007 (UTC)

History
"During the Vietnam War, the Marine Corps decided they needed a standard sniper rifle.[2] After testing several possibilities, they ordered 700 Remington Model 40x rifles (target/varmint version of the Model 700 bolt-action rifle), and gave them the M40 designation"

They ordered 700 Remington 700s? That seems like either a very strange coincidence or a typo. —Preceding unsigned comment added by 98.249.51.26 (talk) 21:37, 24 March 2011 (UTC)

M40A1 pictures
Why is there no pictures of the M40 and M40A1 models? The A3 model looks like shit.. and why is there a pic of a M24? —The preceding unsigned comment was added by 218.101.75.57 (talk) 08:03, 15 March 2007 (UTC).

Okay, I'm deleting the M24 Pictures and putting them in the M24 page Chinese3126 23:21, 29 April 2007 (UTC)

Manufacturer
The manufacturer is missing from the specifications table. 74.12.81.178 06:34, 4 July 2007 (UTC)

Costs in synopsis
"The A3 model costs $3,200." - What does this mean, is this in USD? is this the retail value, for citizens or the army, or is it the manufacturing cost. I don't believe this belongs here. 74.12.81.178 06:36, 4 July 2007 (UTC)

Winchester 70 or remington 700?
These weapons are almost carbon clones of each other. I read that the M40 was based off both of these weapons, since they were so similar. Is this the case or am I mistaken? Someone please respond regardless of whether I'm right or wrong, because I've wanted to know this fact for a while. respond here or on my talk page. Thanks for your time. --MKnight9989 20:17, 21 October 2007 (UTC)

You would be mistaken, as there are many design differences between the Model 70 and Model 700 actions.

First, the Winchester action is a "controled feed" action, which means the bolt face takes positive possession of the cartridge from the time it pushes it from the magazine feed lips until it extracts and ejects it after firing. The Remington action is a "push feed" action, in that it only pushes the cartridge ahead of the bolt as it loads it into the chamber. Then, it has possession of the cartridge by use of the extractor when it pulls the cartridge from the chamber for ejection.

Second, the Winchester action uses a swinging safety that is mounted on the upper rear of the bolt cap. I believe the Winchester safety also locks the bolt closed when engaged (no bolt release knob). The Remington safety is attached to the trigger group housing, and extends up to the right rear side of the bolt body. The bolt of the Remington can still be actuated and/or removed with the safety engaged (removal being achieved by using the bolt release button).

There are other differences in the actions as well. —Preceding unsigned comment added by 209.244.31.40 (talk) 17:10, 10 September 2009 (UTC)

New variant: M40A5
The April 2009 issue of "Leatherneck" magazine mentions that the PWS is working on a successor to the M40A3, dubbed the M40A5. It contains that latest M40A3 product improvements such as a detachable magazine, but will also feature a threaded barrel for mounting either a muzzle brake or a sound suppressor. --D.E. Watters (talk) 22:37, 7 May 2009 (UTC)

Cool, not sure about the detachable mag (those have been very hit and miss with this rifle) but like the fact that the Corps is moving to a threaded bbl.--Mike - Μολὼν λαβέ 23:43, 7 May 2009 (UTC)


 * According to literally every source I can find, as well as simply looking at it, the M40A5's magazine holds 5 rounds, not 10. Alex T Snow (talk) 19:48, 12 February 2015 (UTC)

Maximum range
The maximum range of the M40A3 is listed by the Marine Corps as 1000 yards, I don't know who changed it to 800m (it was formally listed as 1000 yards on the page). If someone was to assume that it matches the range of the Army M24 rifle, that is false. The Marines themselves gave the rifle such a range, and the Army themselves listed the range of the M24 as 800m. —Preceding. FeralLynX (talk) 12:08, 5 December 2010 (UTC)

Designation
A bit of insight as to why the A2 and A4 designations were skipped over would be a good addition to the page. Spartan198 (talk) 09:04, 16 April 2012 (UTC)

Differences between M40 and M24
The article states "Additionally the Army's version allowed mounting of a night vision scope, whereas the older USMC versions were tied to the daylight Unertl 10× limiting sniping operations with the M40 and M40A1 from dawn to dusk." This is untrue. The USMC used the SIMRAD KN200/250 (I don't remember which it was) as an attachment to the Unertl using special scope rings. The USMC also fielded the AN/PVS-10 day/night scope, which could be installed instead of an Unertl. Since then, the AN/PVS-22 has essentially made these older systems obsolete. The AN/PVS-22 could be fitted to the M40A3 by the addition of a picatinny rail section on the fore-end of the stock, which was being implemented as early as 2006. The picatinny rail is now standard on the M40A5. — Preceding unsigned comment added by 165.91.178.67 (talk) 23:34, 11 April 2014 (UTC)

12 RPM?
What is the source for the rate of fire? Using 5+1 (5 in internal magazine and 1 round chambered) as a start? ...or loading all by hand? If a 10 round detachable mag is used, I believe that the rates would be different from the 5 internal magazine. — Berean Hunter   (talk)  03:47, 25 September 2015 (UTC)
