Guys, i recently bought a 15 round mag for my CZ .22lr. Its a generic, and although it fits in the rifle, the bolt doesnt move smoothly past the magazine. Ill grab some photos tomorrow but any tips would help.

Check the height of the mag in well, check the lips of the mag,

I use dykem or prussian bluing, apply some to the mag lips and then work the bolt. Where the bluing is worn off that is where it is wearing/rubbing.

Then determine if material needs to be removed or lips reformed. Or mag catch adjusted

Thanks hollils, ill check it when i get home.

Side not, Magazine fit is not precision, But, take a little bit off and try again. If the mag is up to high the bolt will drag, too low the bolt will not strip the cartridge off the mag.

Also check the follower, too.

I would make dummy rounds to check the feed (safest way).

The follower won't effect drag, if there are rounds in the mag.

Also check spring tension (highly unlikely) If there are rounds in the mag, too tight than there will be resistance to having a round stripped from the mag, too lose, failure to feed.

Regarding AR lowers/parts in general,
Definitely stay away from Century Arms ARs (not to be confused with Centurion Arms who currently makes great MK12 uppers http://www.m4carbine.net/showthread.php?t=20131).

Anyone familiar with these triggers?

I tried to order a Chip McCormick trigger this morning, and was told they'll be out of stock for the next eight weeks, or more. Disappointing.

Never fired anything with a Timney trigger however I have seen lots of gunsmiths use them as upgrades in better hunting rifles. Brownells has them too.

I looked at their website and it looks like they've been around since 1946. That's a good sign.

Here's a good review on triggers from AR.15.com. It seems the trigger I was recently considering might have issues when trying to fire surplus 5.56. I think I'll opt for one of the others.

I've got the RRA 2 stage Comp trigger in my Bushmaster. Affordable and I've never had any issues with it.

[gaijinsamurai]

I'm leaning towards a single-stage trigger right now. Perhaps the JP.

Also, I'm looking at barrels. I want a heavy 20", and am debating between chrome-lined or stainless. Rock River has some good looking ones, and decent prices.

Hey, that's a pretty cool little video.

[Dspec]

hoping that someone can clear this up for me,

I have decided to give my old faithfull .243 model 70 a bit of a makeover starting with a synthetic stock.

One drama that my googlefu cannot seem to overcome is what kind of stock fits the winchester model 70 XTR, short or long action?????

also has anyone had any experience modifying model 70's I am looking at a few different ideas but it is great to see what others have done

Cheers

[mcgn21]

The 243 would be a short action. What kind of mods do you plan to do?

[Dspec]

1. Hogue overmolded stock (black) plus bedding
2. heavy barrel
3. harris bi pod
4. Fox 6x14x40 mil dot scope

which would cost all up about $1500


or on the flip side i could get a Remington 700 SPS tactical plus scope for the same price.... hmm decisions decisions...
