Update on the SBR.. Few things have changed.
-Geissele SSA now is replaced with the Geissele SD-C (flat trigger face)
Once I tried one of the flat geissele triggers, I didn't have the slightest clue what I was missing until then. I have larger hands and the little extra reach and flat face really felt like a better pull for me. The flat/straight to the rear pull was a little easier for me. I tend to reach lower on the trigger and I still have a nice flat pull. Almost feels lighter then the SSA. Absolutely nothing wrong with the SSA or SSA-Es as I still have them on many rifles. But this trigger on the Go-to SBR just feels right.
-Vltor A5 System and E-Carrier.
With insight from BradfordT and others with success on this combo, the rifle runs cleaner and just feels better suppressed.
-KAC MAMS and QDC Suppressor replaced the Surefire Brake and RC & mini
While I absolutely love the SOCOM series suppressors and for the money I would say they are still the best in the biz. I have a KAC QDC CQB suppressor also on hand. As this is my Go-To training, HD, etc etc rifle, I have been doing a lot more un-suppressed shooting and using the rifle in classes, etc, etc. The MAMS is considerably less evasive on a 11.5 then the Surefire brake. I also have been using the SOCOM mini a bit more then the RC. Even though it was only an inch or so, getting in and out of the Polaris and the truck made it marginally easier. Probably in my head but never the less its shorter. With the MAMS still even shorter and 3.8oz lighter (MAMS and Suppressor combined) and I feel has slightly less flash then the socom Mini, but comparable performance, with the rifle being used more unsuppressed, I felt the best option was switch to the MAMS and QDC suppressor. Also I carry it through the woods on the property a lot. With all the garbage and suppressor strapped to this thing, it adds up in weight.
-KAC Front sight made it on the rifle.
After using the CQBL-1 as my backup, in the day time more then 30 yards was really not a viable BUIS option. It was too hard to see. Night was no issue. Day time didn't work that well. As the M4s would most likley never fail, I decided to run BUIS's also for peace of mind. All my rifles had them but this one. The switch coming unplugged on the laser under fire was previously an issue that was remedied with a rubber band, the KAC micro sight installed flipped around, perfectly touches the plug and does not come out no matter what round count or recoil. The only issue this brings up is that the front sight has to be removed to replace the CQBL-1 battery. I tested POI from removing the sight and installing and constantly within 2moa of previous zero. I had to move the SR-D-IT switch back 2 notches for the KAC iron front. The front sight is in the fixed upwards position and will stay that way.
-Bobro mount replaced with ADM
This was not my plan. I love Bobro mounts. But with the rail space it takes up and with wanting to run PVS-14, I needed the little bit of cantilever mount on the optic. I had an M4s with ADM mount, so optic and mount switched with another rifle. It gives me enough space to still have my rear sight and the optic in desired position and add my magnifier if needed or PVS-14s when needed.
That's it for now.. The continued evolution of the rifle. It truly never ends. But I have to say this thing runs and runs. And with my new found love for Fireclean, it is a lot easier to run it hard and clean up after. The second to last pic is this MAMS with Aprox 800 rounds on it after it was cleaned up with fireclean. The KAC MAMS directs some of the bast towards the mounting surface on the KAC can/MD. When NOT using fireclean after a few hundred rounds it would become harder to remove and have to yank the can off. Now with the fireclean, I don't have this issue. (was mainly on heavier rate of fire) See the last photo for the MAMS where the arrow is pointing. This is on another one of my rifles. Where it is scraped off at the arrow is where the carbon builds up. This was without fireclean and needed a carbon scraper.
