DPS from United States, TX Public Profile

I wasn't sure if this kit was going to work on my Bushy AR-15 because I installed an Osprey Gas Piston kit. My concern was if the bolt would fit if the piston rod extended too far into the receiver. No worries!

The bolt fit perfectly. I took it out to the rand after a few minor adjustments to windage I was hitting the bulls eye at 25 yards without issue. I was using Winchester bulk ammo M22 black tip.

What I don't like is the full length magazine that holds only 10 rounds. They make a full length magazine that holds 25 rounds but they aren't included in this kit. Its not easy to bench rest an AR with a full length magazine in .22LR or 5.56/.223. I will most likely buy three 10 round magazines and two actual 25 round magazines. These 10 round full length magazines are practically worthless.

I have been a fan of Leupold optics for years. I have the Vari-X II in glossy finish on my first rifle, Remington 700 ADL .30-06. I sold that rifle years ago and regretted it.

Later I bought a Browning X-Bolt .30-06 FLD and bought this updated VX-II. The older one I had needed a coin or screwdriver to adjust W/E. This newer model has turrets you can adjust with your fingers. A huge improvement over the older model.

About 5 years ago I called the man I sold that ADL to. His son didn't take up hunting like he wanted so it sat in the safe for a long time. He sold it back to me for exactly what I he bought it for. I got my rifle back.

The Gold Ring warranty is bullet proof. I removed the scope and sent it back to Leupold for repair. The scope was 80% rebuilt. The only thing they could not do was add the finger adjustable turret. Oh well.

All scope manufactures offer a lifetime warranty on their scopes. They had to in order to compete with Leupold. Not all warranties are the same. Leupold offers the lifetime warranty no matter how old the scope or who currently owns it.

Springfield Armory offers a lifetime warranty only if the current owner is the ORIGINAL owner. If you sell your SA firearm the lifetime warranty is void. Hmm.

I had been a fan of Leupold base and dovetail rings and single base for years. I never thought I could find better scope mounts. Then I saw a video on YouTube about custom long range rifles and they used the Talley rings. The Leupold single base and rings uses very old technology developed in the 1960s and 70s. The single piece based has windage adjustments on the rear ring. Why? Because back then the scopes were limited to the amount of windage adjustments so the rear rings would make up the difference.

Well fast forward to 2018. The technology for scopes has advanced so much that the rear windage adjustment on the rear rings are no longer necessary. The scope has enough adjustment to make the old Leupold base obsolete.

I really like the very clean look of the rings that I have them on my Browning X-Bolt FLD and Remington 700 both in .30-06. I haven't yet decided to swap out the Leupold base and rings for my Ruger 10/22.

These are the best rings for the money you can buy.

I was hesitant to buy this conversion kit because I have an Osprey gas piston kit on my Bushmaster Carbine M4. The piston rod extends into the receiver which cycles the bolt carrier.

After installing the kit I took the rifle to my shooting club and fed about 25 rounds through it without any misfeeds or cycling issues. I have a Romeo 7 red dot scope on the carbine and after a few minor adjustments to windage I was hitting bullseye at 20 yards or about 60 ft. This is accurate enough for squirrel and rabbit hunting.

I am very pleased with the conversion bolt. However the three 10 round magazines are the same size as a 5.56 30 round magazine which makes it hard to shoot from the bench. I called CMMG to tell them that I like the conversion bolt but not the long magazines. They told me that another company sells 10 round magazines that are the same size as the 5.56 10 round magazines. They have no plans to make their 10 round magazines any shorter.

The kit that I bought has three long 10 round magazines. I'll likely see all three on eBay and buy two of the shorter 10 round magazine and two of the long 25 round magazines.
