Arrived VERY quickly. My version was made in Italy. Came with two 28rd magazines. Nice feature on Chiappa mags is their built-in thumb tab to help depress the spring. Every little bit helps!! Overall the barrel & bolt carrier were pretty clean but I did field strip, clean & oil. I have used this on three AR-15's. A full size Olympic Arms A2, An Olympic Arms M4 and a mid price Palmetto State Armory. I've seen mixed reviews on these uppers but this one functioned flawlessly on all three lowers. I shot it on three different trips to the range. (with a cleaning between trips) I used CCI Stinger 32 grain 1640 fps and Aguila 30 grain 1700 fps. I paid 5.99 for 50 CCI and 3.79 for 50 Aguila. ZERO FTL's FTF or FTE with either ammo expending around 200-300 total rounds each time out. I'm older so I put a carry handle on it with a direct mount 4x Leapers with bullet drop compensator. My local range goes out to 85 yards max. With my eyes and whatnot, I can ring a three inch gong with most every round in the mag! If you've got more than one lower, you should consider one of these. The ONLY drawback...Buds used to offer these for $168.00 but mine is worth the $238.00

I finally had a chance to take this prized possession to the range. The bolt failed to extract the first round that I fired. The FIRST bullet! Sadly, there is no other way to describe this product than by calling it what it is: a Piece of Overpriced Junk. I would love to give it the benefit of the doubt; however, there is no doubt that if I had needed to rely on this weapon for personal safety, I would have been dead. Several gunsmiths, armorers and Special Forces Weapons Experts were all incredous. 2 of whom were on the range with me and thought I was trying to pull a fast one on them. Don't walk away from this item, run.

Was impressed with unit and I have seen many 22 223 conversion units but this is the complete upper ,did have the customer bring it back but was only a small adjustment with the "RECEIVER PIVOT PIN" Colt rifle has the large pin and Chiappa uses small 1/4" I did not keep them in stock but instead used a stainless bolt and aircraft nut worked great but now keeping small pins in stock COLT - RECEIVER PIVOT PIN, .250", SCREW TYPE 160-308-121WB Brownells so if you get this spend another $7.00 for the small pin.

So far this upper works just fine for me no issues! I have tried this on a DPMS , PSA, and CMMG lower and it worked fine on all three! I'm very happy I picked this up!

This is a great addition to my AR, and the price is unbeatable. It allows me and the whole family to plink and still get to use the upgrades to my lower.

Bought these uppers on sale for a cheaper price than 2 conversion kits for an AR. Now myself and a friend have a dedicated upper with 2 magazines with no messing with converting. An added benefit is we both have a barrel made for .22LR rather than the .224 5.56 so the bullet engages the barrel rather than bouncing down a very slightly large diameter bore. Bud's shipping is always fast, and I continue to buy from Bud's.

This works fine, but is a piece of junk. Mine arrived in horrible shape. Pitted bolt with punch marks on it, corrosion on barrel and front sight, absolutely filthy. Looked like a "second' that had been stuck away in the back of a humid warehouse and then they decided to sell it. Receiver is plastic and I suspect it will wear out after a couple of thousand rounds. If it had shipped to an FFL rather than my house, I would have rejected it. Started to make a warranty claim, but cleaned it up and decided to shoot it. Works great and reasonably accurate. It cycles every type of normal ammo I have and will cycle CCI quiet ammo about 3/4 of the time. So, decided I bought a $140 toy gun and will live with it. .Three stars because it works well, but still won't advise anyone to buy.

Not bad at all... In fact, better than "not bad" for the price. I mated it to my Adams Arms lower had it zeroed in 12 rounds (spare Magpul MOE rear sight with the provided front sight. I then mounted and inexpensive holo-sight I had picked up and zeroed that in another 6 rounds. My girlfriend then fired 4 mags through it without an issue. I recently purchased a poly lower that I haven't tried with it yet. I plan to make them a permanent pair. All in all, I've got a $330 .22 AR with a that, so far, has fired without a flaw and prints a 1 inch group at 50 meters; probably more due to skill and sight limitations than the product. Very good buy.

This upper doesn't come across as high quality but it looks good enough. The important thing is it hasn't been picky at all. I've only run a few hundred round through it on two trips out to shoot but I haven't had one failure.

Well today was the first time I was able to take this to the range and test it. The bolt fails to push a new round in after each shot so you have to hit the battery assist EVERY shot. On top of that, the rear slot for the take down pin is cracking all the way through and may very brake off the next time I try and install it. Hopefully I can use a dremel and some JB weld to repair it. Very frustrating.
