I have looked at getting an upper in 6x45 since I have a few ARs and like anything 6mm.

What weight bullets are you using?

This newest bbl I put on a baked graphite black Cerakote finish. It matches the upper very close. I used a Mid West Industries free floating handguard. I used a YHM gas block with flip up sight and a DPMS detachable rear A-2 sight. I haven't decided on a scope yet. Might just sell the upper once I test fire it.

Are you looking for a Southern Va Gatling Gun! Or still looking for a rifle for Matthew? Scotty

It would be neat to have a small 243 in the AR-15 platform.

I think 2900fps out of a 16" is great. I was looking at 20" barrels.glane5910":1hcxgemf said:With the 16" bbl I'm getting 2900+/- FPS depending on powder. I forgot about trying the 80gr Barnes TTSX but I can't find the speeds I obtained.

It's not too bad. You should get around 3000 and change out of the 20". The 24" gets 3117. This is using Ramshot Exterminator.Woodycreek":17761xco said:I think 2900fps out of a 16" is great.

I think a AR in a 6x45 would be cool as heck, but I'd love to have one built on a small Sako or short Remington action. LW 22-23" tube and lightweight synthetic stock like a Bansner or McMillan EDGE. Actually, two stocks, as that would probably be a skookum rifle for Little Man to shoot some hogs or a deer with in a couple of years.
(Then I'd have to figure out a way to get us on some good hog-hunting land in Texas!)

I just can get 2900 and change with the 60gr BT and Benchmark. In 223 of course!

Not in a Rifle but I have had a Custom Remington XP-100 and a Bullberry Contender Barrel chambered in 6x45mm.
Out of the Handgun Barrels I was obtaining 2650 FPS with the 80gr. Speer Hot Core Spitzers. That is the bullet I used for Whitetails with good success. For Varmints I mainly used the 60gr. Sierra Hollow Point at 2900 FPS or the 70gr. Hornady SX at a bit over 2800 FPS.
In addition I have used the Improved version of the 6x45, the 6mm T/CU in a couple of Contender Handgun Barrels. 55gr. Nosler Ballistic Tips out of the 6mm T/CU at a bit over 3000 FPS was a Varmints worst nightmare.
The 6x45mm is a very neat cartridge and performs much better than you'd think it should. I have always obtained great accuracy from this cartridge as well.
Some day I just may have to pick up an AR Upper in this chambering.

These 6x45's in AR's are just plain sweet. Just got back from test firing my newest build. I started with the gas port at 0.81" but it wasn't cycling properly(ejecting but the carrier wasn't going back far enough to pick up another round. I went up to 0.085"(same as Les Baer uses in his 16") and it ran like a top. Now its got a M-16 carrier so it's heavier than the semi version. That might be why I needed th extra gas or it might've just needed broken in more. The cases ejected perfectly, 7-8 feet away at exactly 3 O'clock in a 1-2 ft pile. I just shot 30 rounds for function. It has open sights now but will throw a scope on it and see how it shoots at distance.
Pretty cool..

The 6x45 may go back on the need list!
