in the 30 August 2004 Issue of Amry Times is a cover story about the second generation of XM-8 prototypes with new changes made after input from soldiers that have used the weapon. i didn't find the article on their website, www.ArmyTimes.com but they do have a 3-D view of the second generation prototype XM-8 on there.
one of the main changes is the combining of the "Designated Marksman Rilfe" and the "Automatic Rifle" into the "Designated Marksman Automatic Rifle" or DMAR. there will be standard 30 round magazines issued with rifles intended for "Marksman" duties and 100 round drum magazines issued with rifles intended for "automatic" duties. i'm guessing those intended for marksman duties will have different optics. thats just a guess from me.
the 17 changes to the XM-8 are as follows.
1. improved bolt locking mechanism and larger bolt release for easier use.
2. increased rate of fire to 800-850 rounds per miunte. this is supposed to help keep the chamber cleaner in adverse conditions such as desert.
3. score marks on the top of the buttstock extension to help soldiers know how far the stock is extended.
4. stronger bird-cage type flash suppressor has replaced the open prong type suppressor. a few early prototypes developed cracks in the prongs at around 15,000 rounds.
5. ambi-charging handle now has a knurled handle for better grip.
6. flip up/down back-up iron sights itegrated into the top of the handguard
(front) and carrying handle (rear). the front sight looks very similar to the M-16 front sight and the rear is a 1 inch tall by 1/4 inch wide post with a hole in the top.
7. windage and elevation knobs for optics can now be adjust with a 5.56mm casing or a small coin instead of the dedicated tool that could easily be lost.
8. windage and elevation knobs now make an audible "click" so they can be adjusted by sound.
9. optics now mount with a lever style clamping mechanism instead of screws which troops tended to strip out durring installation of the optics.
10. improved handguard with upgraded heat resistant material and added heat shields to guard against heat damage durring sustained fire.
11. increased range of infrared pointer and illuminator from 600 to 800 meters.
12. optics controls are now on the rear of the optics unit instead of the side so soldiers can adjust and see the status of the optics easier.
13. optics controls are larger and now have "+" and "-" signs instead of up and down arrows.
14. battery life for optics unit is increased from 110 to 400 hours.
15. the DMAR now has a heavier and fluted barrel for lighter weight and better heat dissapation.
16. Bi-pod legs for the DMAR have been redesigned and can now be adjusted for length and each one can be independently adjusted for uneven terrain and they have been shortened so as not to interfere with the support hand with firing with bi-pod folded.
17. improved buttstock for compact carbine models to allow for easier shouldering of the weapon while wearing body armor or load bearing gear.
the current Gen 2 XM-8 prototypes are all black but production models will be more earth tone-ish.
man i REALLY hope H&K makes a civy version of this rifle. i'll be first in line if they do. all they need to do is put a semi-auto trigger group on it and presto! awesome rifle for the private market. no more worries about "evil" features. keep your fingers crossed. i also hope they offer it in different calibers. it would be fun to have a 7.62x39 and a 7.62x51 version of this thing too.
