View Full Version : Wanna build a 22 Long Rifle upper for pistol lower

17 December 2014, 22:00
Several months ago I finished a 556 pistol build. I'm looking to do a .22lr upper for the pistol lower. Anyone have any experience with this? I wanna get an idea of what parts were used and how well they function. My intent is to use a 4" barrel so I can run standard velocity ammo through my suppressor without it going sonic. Thanks for any input.



ps - and please, no suggestions for a dedicated .22; I've already got a S&W 15-22. I wanna run the short barrel and suppressor combination to avoid the cost of subsonic ammo and avoid ANOTHER $200 tax stamp. Thanks again.

NICE!! I didn't know Spikes had a .22 upper. Will have to look into that Hope they do a 4.5" barrel. How's your accuracy and what flavor ammo does it like?

Rainier Arms (http://www.rainierarms.com/rainier-arms-ruc-22-lr-upper-black) has one too (only 1 left though).

Also CMMG (http://www.cmmginc.com/category_s/1950.htm) makes a bunch of them too. I've currently been eyeing CMMG's uppers, as they are also a bit cheaper than Rainier Arm's RUC .22 I've had good luck so far with CMMG's customer service. Emails are usually replied to within a couple hours or less.

Does Spikes Tactical still make parts for .22? Their .22 barrels haven't been in stock for a while. Only thing I see in stock is their .22 BCG.

I've been using a Taccom 4" lightweight barrel, Silencerco 22Sparrow stainless suppressor, CMMG nickel-plated bolt group and Black Dog magazines for quite some time. I like the CMMG solid poly charging handle (fewer jams) and I use the CMMG 9mm removable ejection port cover/brass deflector (with port cover removed) in a standard AR upper. This is probably my favorite setup ever. It's just so fun to shoot .22lr accurately as fast as you can without ear pro [:)] Even with just a 4" barrel, I can shoot 25 rounds into 4" at 25 yards offhand with a Trijicon RM02. I'll post some pics if I have some time over the holiday.

oh don't get me wrong they don't make stuff for .22 any more lol
you mite want to try
Taccom first
CMMG second

mine runs 99.99% of the time most of the 00.01% ammo related
i never tested the accuracy i just blast a way
but my 16 SPR in .22lr that is a hole different story

Thompson - I was looking at the CMMGs but didn't see one with a 4" barrel already assembled. Will have to look again. Wouldn't mind something already built, but the ones I did see seemed a bit pricey. However, I haven't added up what the pieces would cost either.

Luis - Sux to hear they don't make .22 stuff anymore. Your vid was pretty cool.

MoxyDave - Would love to see pix! Your setup seems to be what I'm wanting to do. I've already got the SparrowII and an optic, just need the rest. And of course, the money to do it with!

Thanks guys!
