I'll make this short and sweet. I posted in the 22 section but havent got an answer.
I just bought a lmt arp 5.56. Awsome gun for sure but I want to shoot 22s.  The drop in is 200 bucks and a barrel and bolt from spikes is around 400.
I have no problem spending the 400 but was interested in finding out how accurate the drop INS are compaired to a dedicated barrel.
I plan on shooting anywhere from 50 to 100 yards with the 22 with 100 being my limit for a 22.
How accurate should I be expecting to be at that range with a dedicated barrel considering I use good ammo and scope ?
how accurate are the drop ins?
Thanks for any input

A dedicated .22LR barrel will be more accurate than a drop-in kit w/.223 barrel due to correct bore size and barrel twist.

My experience with a Stag 1/9" 16"barrel, shooting 36grn copper jacketed, or copper washed is:

from 10yrds it shoots a little low.
from 30rds it shoots damn near perfect with my optic (that is zeroed at 50yrds with .223)
from 50yrds it shoots close to perfect but a little high
From 50+ I have not had great accuracy at all.

In short, if you plan on shooting 100yrds, get yourself a upper and build a dedicated upper for it with the correct barrel and twist.

Thanks for some input. I really didn't know what I was getting myself into with a barrel as far as accuracy. I knew it was better but didn't know by how much

Or buy yourself a Smith 15-22; $4c sounds like a improbably great price from Spikes.  Have they come down?
Baloo's info was helpful; not shooting to the sights is among the reasons I never pursued the .22 conversion.

Here's a vid of my CMMG in my Bushy HBAR: Youtube vid of CMMG drop in unit in a Bushmaster XM15

My CMMG does just fine at 25 yards - shoots very clost to point of aim as set for standard 5.56 ammo.

Can't say how well it groups beyond 25 yards.

I like it because its easy to move from one rifle to another and works very well - I've had 100% function so far.

I did smooth the working surfaces with lapping compound prior to shooting it though as they were parkerized.

For 50y to 100y get the .22 upper.

The drop in convesion kits are for training use, not precision fire.  In my experience they keep a 1" group at 25 yards and open up significantly at 50y (enough to keep it on a pie plate at 50 - but you're not going to bust a squirrel reliably).

Where can I get a good dedicated .22 upper?

I love my Spikes Tactical, shoots great. The nice thing about a dedicated upper is you don't have to readjust your optics (if you have them) when you switch back and forth.

I just wish the bolt catch actually worked, but I think all 22 uppers use the magazine follower to keep the bolt open. Is that true?

Somebody now makes a .22lr conversion Bolt release that allows you to use the hold open like a standard caliber set up.  So you can drop that into the lower, get a upper with mags and you really do have the closest thing to a accurate training rifle possible.

ETA: 22catch

Go with Spikes.  They have many options and will custom build pretty much anything you want. I have a complete ST-22 from Spikes.  I even sent them a 9" LaRue quad rail that they installed for me.

i talked to spikes since they actually make a barrel for the lmt mrp 5.56 but Tom pretty much said its only good up to about 50 yards for the accuracy im looking for. Maybe im kidding myself and a 22 wont shoot good any further then that? Tom did mention something about a lothar barrel thats match quallity. but he couldnt make it for my ar. i was told i got an email explaining why but i havent gotten it as of yet.
All i want is a bolt and Barrel. i dont want to change the whole upper.

For 100yrd accuracy you may just get a purpose built shooter like a bull barreled 10/22.

As someone mentioned, the 22 setups really are geared more toward training, especially close quaters drills.  That is how I run mine and love it.  You will blast through at least 500rds with each trip.

A cost effective option would be a kit for what you have to practice CQB and a seperate accurized .22lr for longer work.

I've never regretted buying my Spikes .22 upper!

I will always recommend this route v. a conversion kit....but I'm too lazy to swap things around to go shoot.
