On Saturday I recieved my M900a! It was the final piece needed to complete my SHTF 16" M4 carbine project.
My thanks to Brightflashlights for the awesome pricing, quick shipping and A++ service! Also thanks to new-arguy pointing me in the right direction!
It was a tough decision between the M962 and the M900a. After going over the different configurations and setups I came to the conclusion that if I went with the M962 I would basically be recreating the M900a in a less efficient and more expensive way. No matter how I setup the M962 there would be certain situations that would make the light hard to use or impossible to use. The M900a really solved a lot of my concerns such bi-lateral use and vertical grip integration.
After mounting the M900a to my SIR 50 I knew it was the right choice! The M900a feels looks and functions like it was made for the SIR. Before I got it I was concerned about it sticking to far down but it just right and does not cause me any problems.
I also contacted Surefire about getting the older shorter battery cap without the master on/off switch. I was suprised to receive an email from their tech support group asking for my mailing address and telling me they would send me one at no charge! That's A1 customer service in my book and I'll certainly continue buying their products because I know they'll take care of me if I ever need anything!
So here's a quick run down of the my setup.
1. Pre-Armalite Eagle Arms pre-ban lower.
2. CMMG/DPMS M4A3 upper with a 16", 4150, fully chrome lined 1:7 barrel.
3. Armalite carrier and bolt, using Wolff extra power extractor spring.
4. ARMS SIR 50 rail system.
5. ARMS 40a BUIS.
6. EOTech 552 HWS.
7. Vltor Clubfoot Modstock and 5 position buffer tube.
8. TangoDown Battlegrip.
9. Surefire M900a with white navigation LED lights.
10. Homemade 3 point sling using 1.5" black webbing with ERB.
So far I have this carbine has been flawless and I have yet to have any malfunctions, KNOCK ON WOOD...
The only other big upgrade I'll get will probably be a ACOG TA31! Damn you new-arguy!!!
I will probably also look into a Knight's single point sling mount and a CQB Solutions SOP sling.
Now I can start planning for my 20" AR project.
I hope my wife isn't reading this...
