I have ordered a Compass Lake .22LR kit and should be ready by xmas. It is a SPR 18" Douglas barrel threaded and capped. Comes with bolt and two 10 rd internal mags / pushed into a regular AR mag. Also, works with BDM's. Cost $625 plus shipping. And yes, the CLE kit should be accurate

Recently built a dedicated 22lr AR, and used CMMG 20" Gov't. Profile barrel with the front sight
I was surprised it was pretty accurate, ammo used on all 3 targets were AE 38hr plated HP/plinking rounds. 15 shot ea.

I don't have the 20 inch government profile, but I do have the 16.1 inch heavy taper and the M4 profile, both free floated. I found the least destructive of accuracy is a thread protector. If I had room in the safe, I'd build an upper with a long and cheap free float tube, that 20" government barrel and a clamp-on front sight all the way out at the end of the barrel. It wouldn't be a CLE, but I bet it would stay under 2 inches at 100 yards. |

I’m going to be using the 22LR upper for hunting. So to define accuracy MOSH minute of squirrel head. So I’m looking for head shots on squirrels.

Quote HistoryQuoted: Both barrels in your original post will do that. I looked at stainless barrels initially, but later I narrowed my options to nitride treated barrels. The heavy taper 16 inch barrels will keep five rounds of Aguila SV under 1.5 inches at 100 yards if there is no wind. Do you hunt with a scope or do you use iron sights? |

I just did a 22lr JP build. I love it. There should be a post somewhere about it.
I will say, once I got the right scope rings it made shooting it MUCH better.

OP -
I have had and sold 2-3 different brands of uppers over the years and here is my take on my next build which like you will be for hunting (sage rats instead of tree squirrels). Beyer barrel and CMMG bcg Or Kriss vector DMK-22 rifle and pull the 10-22 barrel and drop in a Kidd ULW barrel....... no one has done this yet so it’s a gamble to see if it works. But from my experience kidd barrels shoot. I haven’t had a Beyer barrel yet but I haven’t read a bad review about one of his barrels yet. If you do build one please post results |

I use the CMMG anti-jam handle. I've had jams from using a ambi CH made for a .223 as the little .22 round somehow gets caught in the groove of the handle and jams the rifle.
In the future I will get a milspec handle and practise filling it with epoxy to give it a similar profile to the anti-jam, before trying it on an expensive BCM, Next level Armament or Raptor. |

If I'd had to fill that void, I think I would have used wood glue or elmer's and a bit of chopstick so it would be easy to remove later without damaging the CH. The other option is to find the cheapest CH you can and see if it caused any problems. |

On My first 22 build, I used a standard charge handle and had a few casings get stuck in the groove. I filled it with JB weld. That upper got sent back to PSA for accuracy problems, so on my second upper, I bought the CMMG "plastic" CH. at first Imwas disappointed that it wasnt metal and looked at the ads and saw no mention of build material. I also dont like the way if I ride the CH, it stops when the latch hook hits the upper reciever. I need to push it forward pretty hard to get it past the tight spot. I need to do a little filing and polishingbto fix it. I ended up doing a rattle can camo paint job on it and the CH looks ok for a plain Jane part, IMO.

PSA 16" nitrided .22LR barrel/bolt Vascar has speculated that the bolts are old CMMG stock that use a roll pin to retain the firing pin. Someone here or at RFC had a bolt with the retaining pin hole drilled too low so there was cracking in part of the bolt. IIRC, PSA accepted the return. If memory serves, an entire upper based on these components was $300 when it was in stock. I marveled at these prices when PSA first ran these ads; I couldn't come close to building an upper for what they were charging. Given subsequent reviews, I think I am better served by the newer CMMG bolts. |

I haven't tested mine past 50 yards with most of that at 25 yards standing or sitting. I have some groups that look like 9mm holes, but 25 yards isn't much of a test. That could equate to 2.5 or 3 inches at the 100. The 20 inch government profile? I've never shot one. I think with free floating and the correctly weighted muzzle device, it would be a fascinating experiment. I test from a bench, but I don't practice that way, so ultimate accuracy isn't as important to me as durability and accuracy over the longer term. I assume that the JP and Beyer products would give better accuracy simply because they do command a premium. PS -Did you get my IM a few days ago? |

Jut got back from the range, but by far this was not meant to be a precision type 22lr. I built it for a retro type plinker.
From my upper n lower having significant...play to a cheap cheap picatiny rail that had significant play side to side, I had to add aluminum shims to get it snug. Mil spec trigger, To a non free float handguard...just trying to find excuses for for my groups, ha At 25 yards 
50y Bottom left groups...shows the barrel has potential 
Set up from today 
In its original build configuration to shoot irons

I'm not telling how to build or what to build, and I'm not even denigrating the S&W 15-22 (though I do believe it has some unfortunate limits). I only note that the ability to use actual AR parts is a big advantage when buying, and nice if you foresee changing any parts around amongst other ARs. |

Quote HistoryQuoted: I don't doubt that's true. I would prefer a 16 inch barrel. You are anticipating use of high velocity ammunition. My experience is that this will cycle fairly hard in with a 16 inch barrel. I think Remington Golden Bullet even gives me "port pop" (noise from the ejection port because the brass is clearing the chamber while some pressure is still present). I think a 20 inch barrel would only make this worse, but I'd be interested in ar671's opinion on that. Where accuracy is the goal, I'd look for the shortest, thickest barrel. Extra match ammo would not cycle but it did. I observed though after sighting in at 50y with the 38gr, aiming at same target then shooting the wolf extra match 40gr measured a drop of 2-3/4" from the 38gr |

My 1st build was a 16" bull barrel set up exactly like my fight carbine. I built it for cheap run and gun. Kinda like a training gun.
It is CMMG bolt barrel and mag. Shoots better than me. Also has their CH. So I decided to do a 20" A2 for off hand practice for CMP. Same recipe. Kits work great. Accuracy rivals any .22 I have seen other than all out benchrest Anshutz types. Mags work flawlessly. Back in 89 I got a Colt HBAR that came with their conversion. It worked and all. It was not very accurate. I almost never entertained the .22lr idea again. I see guys shoot converted 5.56 guns. Still not impressed enuff to invest. THEN I saw the dedicated barrels. Glad I did Today I even have an Advantage Arms dedicated Glock 17. Couldnt be happier with both!. |

I’m looking at my next build being a 22LR, but I’m torn between two barrel brands. I would like your opinions on JP vs Beyer barrels for accuracy, weight, and value. I know JP Super match kit is $500. Thank you ) but I do have his rifles.
When you get into this price territory, I'm sure both Beyer and JP will shoot, and I'm sure both would replace the barrel if it doesn't perform. The question is when you combine the cost of barrel/bolt/charging handle, which one fits your pocket better
