18" or 20" ????

Which to get. I'm looking at the Alexandria Pro Fab uppers.

Opinions?

A few fps or a few ounces or a few inches sight radius...

Age old question: What are you going to use it for?

The cool kids would go 18 inch with rifle length gas. :D

ETA: You asked for opinions ~ I've spent time with 16, 18, 20 and 24 inch barrelled AR10's and my favorite was a medium contoured 20 incher (iron sights), followed by a heavy 16 inch SS match barrel (optic) with mid length gas.

I went 20", it's got a mid-length gas system.

The above was all I could come up with, just wanted to be sure I wasn't missing anything.

I just need a lower build kit and some optic of some sort.

Guess I'm going to have to sell my FAL's now, and all.

Have 18", 20" and up to 26" AR 10's. Like 18" and 20". It's a big rifle, an extra two inches doesn't hurt handling. Have two with barrels that weigh over six pounds. Just the barrel weighs more than some AR 15's with optics. If worried about small spaces then a 14.7" AR 15 is your ticket. If not for the astehetics of the FAL and went on pure performance would sell all my FN's, M1a's, CETME's, HK 91's and replace with match barrel AR 10's as accuracy plus ease of assembly is much better with an AR 10. But I am not that smart, like my big old clunky battle rifles. A jumbo AR 15 just doesn't have the same nostagia. Like an early 70's Mopar with a 440. Sucks gas, is heavy and a Honda Accord will out corner it but which has the most cool factor?

I have the Pro Fab 18" and happy, I don't think another 2" will do much for me while I don't shoot long range. 18" balance well with adjustable carbine stock and easier to carry around. If 20", probably will go with rifle fixed stock.

As an update, I cancelled my order of the upper as I had some unexpected expenses come up. I'm just getting the lower receiver for now. But, that is the part that goes out of stock more often.

These are DPMS compatible.

PSA has their .308 lower for less ($99 with free shipping) but they are not compatible with other manufacturers IIRC. I wish I would have jumped on this lower when it was $95 and saved $20.

May have some spare Palmetto blem AR 10 uppers and realized had a dozen AR 10 charging handles must have misordered thinking were AR 15 as never order double digit AR 10 parts at a time.

PSA has their Gen I 308 uppers (18" stainless Mid Length gas) on sale this weekend with free shipping. $419 with standard HG and $499 Keymold free float. I guess they are clearing out GEN I for GEN II. I decide to pass, don't want to mess with 308 AR compatibility, definitely good deal if you have PSA lowers.

Don't personally want their complete uppers, rather spec my parts and screw together myself. Besides, my entire point of the AR10 is ability to build rifles in odd cartridges that make no sense. Already too fat on 7.6251 launchers. Now that 22 Nosler is available and starting my second build on poodle shooter platform my idea of an AR 10 in 22-250 is senseless. Unless some of the $800 22-250 match AR 10 barrels fall so out of favor go on super clearance. If not for 338 Federal would have never screwed together my first AR 10 but found some nice end of year clearace barrels for under $150 each. A 338 battle rifle lobbing 250 to 300 grain bullets is just cool. Then fell into the 6XC totally by accident and realized the potential of jumbo poodle shooters. Now hoping somebody will start offering a standardized longer action so can shoehorn 300 Win Mag length cartridges and build an autoloader out of my favorite 7mm's. Can see a mag dump of 7mm Practical smoking a throat in under a minute.

Can you elaborate on the 338 AR10? Did the barrel require extra machining? What type of mags work? What is the total weight without optics and are any parts prone to breakage due to increased stress? Was the build straight forward or was there a lot of custom fitting required?

Standard off the shelf 338 Federal AR 10 barrels. Actually reasonably popular and find on clearance occasionally. Palmetto used to even sell them. Just a 308 necked up to 338 but SAAMI accepted. White Oak made a run but are out of the AR 10 business. Google is your friend.

I use Youtube more than Google and it was helpful in this case.

Two of mine have 26" W.O.A. barrels profiled from Kreiger blanks. Weigh over six pounds each. Carry from truck to bench is about all you want to do but if something pops up out at 600 yards or farther they are beauties to sit behind.
