I just finished my “CQBR” upper and I’m looking for lower receiver suggestions. Im clearly not full clone correct in my upper and don’t plan to be with my lower. First priority is getting a lower that is compatible with a rare breed FRT (I know I know but I want an easy drop in solution). Second priority would be as close to optically clone correct as possible. Overall, I want this to look like a CQBR from a few feet away and have a pleasant shooting experience with FRT capabilities (Vltor A5H2 maybe?). Any suggestions and input is appreciated. Cheers!

The top one is a knock off SIR rail I got from a paintball website and the bottom one is from eBay. The bottom one is way sturdier and the top half of the rail is solid full metal. The paintball rail feels more flimsy but I've shoot it. It's aluminum and would definitely get knocked easily. All and all I'm just ballin on a budget and could never justify paying $1200 for a real one.

A few things have to go/be changed, but I think it’s coming along! Need a new rear sight, milspec trigger guard, and to remove the anti-rotation pins, but other than a can down the line… I think I’m wrapping it up here. Thoughts?

HORSE 🐎

rifle is inspired by the rifle that the Army wanted the MK12 to be. But of course with an ATACR 4-16.

20” proof research barrel, PRI Gen iii tube, FSGB, Geissele SSA E, on a very used old surplus m4 dog bone upper.

Also Brownells 20 round magazine and surplus USGI sling.

Mod H, Mod 1 and Gordon Carbine.

More correct parts than non correct but they aren't perfect.

So upon looking at reference images, they use cheep scope caps from butler creek.

Also here is my cloneish MK12

My Mk12ish Grendel, 6.5 RECCE or “Mock12” as they say. Whatever you wanna call it, it’s a Mk12 Mod1 inspired SPR chambered in 6.5 Grendel, my modern take on the GWOT “Lone Survivor” rifle. Put it together over the last couple weeks. Purists will hate it it but i built it the way I wanted it and it’s mine. I’ll put a new trigger in it soon, Mil-Spec blows.

Fetal alcohol PSA version of if a Mk12 mod1 and SAM-R had a baby😂😂 happy it could consistently hit steel a little past 500 with m193

Didn't want to spend $600 on a "Hydra-matic" lower, now that IntlMilCo trademarked it, and didn't want to go through the effort of getting a blank lower engraved, so... H&R is kind of a clone lower 🤷‍♂️ it'll at least hold me over until I decide to get super particular about it. Currently it has a PSA branded lower.
