Thanks! I'm giddy about this thing right now! the Karl Nill grip was almost an afterthought, I was originally just going to get a Magpul MOE+ and be done with it, but seeing my friend have one of the adjustable ones on his Swiss Arms rifle made me really wonder. After thinking about it for a while I decided a little bit of contrast would be good, and pulled the trigger.
If you haven't actually held a rifle with a Nill grip, it really is something else! I can honestly say without any hesitation it's the most comfortable grip I've ever held (by far). A little heavier than your standard Magpul grip is, but the weight is at the rear of the gun so it's not bad at all. Very pricey though, at about 270 bucks once shipping and export licensing is finished, HOWEVER with the classic look, and how amazing the grip feels I think it was worth it! And I think I have this issue with making guns nobody else has

. It really sets off the contrast compared to a sleek black rifle.
For some specs; on the rifle:
Upper:
- Vltor MUR-1A upper receiver
- Motuik MFG full auto bolt carrier group
- DPMS steel charging handle with Badger Gen-2 tac latch
- 16.5" hammer forged / nitrided barrel - midlength gas system
- Vltor low profile gas block
- Grifiin Armament M4 SD II flash comp
- Diamondhead USA 10.25" handguard w/ custom bipod stud
- Magpul AFG
Lower:
- Alberta Tactical Rifle Gen-4 AT15 lower with ambi bolt realese
- Norgon Ambi mag release
- Karl Nill hardwood grip
- Magpul UBR rifle stock
- basic trigger group and safety
Optics:
- Leupold CQ/T Rifle scope
- Leupold Delta-Point w/ 7moa Triangle
Stuff I have coming or want still:
- Geissele Super Semi-Auto trigger or Super 3-gun trigger (not sure which one I want yet)
- BAD-ASS Ambi safety with 2 fullsize levers (needs some mods on right side lever to work with Nill grip, as it doesn't have the ambi safety cutout)
- KAC-SR15 buffer and carbine buffer spring
- Offset iron sights (have a couple options I'm looking at)
- Rail for flashlight for 6P LED Defender
Everything but the offset sights and the trigger is on it's way to me right now, so hopefully I should be able to get it mostly finished this week.
I'm also thinking about going for a Rainer Arms RAPTOR charging handle, or a BCM Ambi gun-fighter, but not really sure if I'll use the charging handle as an ambi feature or not... I know the safety, bolt release and mag release are really nice to have (you can actually use your trigger finger to release the bolt after a mag change which is really slick!)
So right now all I'm actually missing is the buffer and action spring to make it work, otherwise it would have come out yesterday for shooting!

The offset irons are the hardest part, I wanted the KAC ones but the forward assist block on the VLTOR won't let the rear go on. So I can either get the shell deflector only, or go with offset 45 degree rail segments for standard flip-up iron sights (the Gear Sector ones are perfect but pricey) or keep waiting for the elusive Diamondhead USA D-45 Swing sights (they sit flat on the top rail and flip out to the side and up at a 45 degree). They are really cool sights but literally impossible to find right now, let alone in Canada.
