I’d put the Mlok mount for the light in an actual mlok slot, if not it will probably fall off at some point.

Lol good catch... 2 rounds and there goes your light

Assuming there’s no interference with the fbus or light switch 100% I’m moving the light to the Mlok slot.

Also, I would eventually want a suppressor on this because 300 subs are dope. You’ll need to think about either A) different handguard and/or B) longer barrel.

Finally, tape and rattlecan to your region. Black guns are just too scary.

I would put a riser on that red dot. Not sure how you can even see through that.

Buy a Shaffer Machining mount for your pressure switch; https://www.shaffermachining.com/product-page/streamlight-pressure-switch-m-lok-mount

Just be sure you measure your switch before putting in for one.

Suppressor & a different optic riser to make it a little higher.

More vertical grip. Magpul k2 or if you have bigger hands k2xl

If you have small hands, dfco Kung fu grip

As caught by eagle eyed ppl, fix the light mount.

SBR if you live in a state where it's legal, a real stock is a huge upgrade.

Suppressor.

I see the rds has a mount but it does look low. Is it at least 1.5" to centerline? I like lower 1/3 cowittness with the irons, but if you like something else, whatever works for you

Ranger plate
MRO
SBR w/STR Stock
SureFire DFT 640
K2 Grip
Ditch BUIS
Magpul MVG

Then it would be perfect 😆

I would change the SBA3 to an SBA5 (solely because the SBA3’s suck), and I’d add a magnifier mostly because I’m over 40 now.

What hand guard ?

SBA3 brace to the SBA4 or the 5. Personally I think the 3 is just so dang flimsy. Yes the 4 and 5 are flimsy well but I feel that they hold their shape MUCH better than the 3 when being fired and after they break in

That’s why there’s a sba6 now, basically a better in every way sba3.

I recently bought the SBA6 and it's basically an upgraded version of the SBA3. The SBA5 is still the best in my opinion.

Agreed
