"scopeless Monday"

[Danny Creasy]

I had recently removed the glass from one of my CZ Trainers and took it to the range this morning to check its zero with some of the Wolf MT that I acquired recently.



I benched it at 50 yards and then fired 10 ten rounds offhand at the top bull from 25 yards. Not much POI change between the two distances. All ten of the offhanders stayed in the 3" orange bull.



I would have put some more rounds through the Trainer at both distances, but I had a new rifle I wanted to test.

I always wanted one of those AR-7s to store in an emergency tub we keep handy (you know, food, water, medicine, the kitchen sink, etc.). I finally picked one up last week.







I read a lot of reviews first, so I knew they were not target rifles. But, it will do what I expect it to do if needed.

It went through about fifty rounds (CCI MiniMag solids) without a jam or misfire. It was hitting low and right (25 yards), but a few adjustments of the rear peep for elevation and the front dovetailed sight for windage and we were on POA. I finished up with one of the eight shot magazines offhand at 15 yards on the little flame dot in the middle. It would definitely take a squirrel, rabbit, or game bird at short range.



The offhand 15 yard group by itself:



Question: I could slide that front sight blade with just some firm thumb and finger pressure. Now that it is on target, do any of you have a suggestion about how to secure that plastic front sight blade. It would move with an errant knock or bump. The ramp is plastic as well.

Scopeless Monday, very nice.

I prefer my Trainer scopeless, too.

Regarding the Henry's front sight, my first thought was super glue. But, I'd have to check shooting a few times by removing and reinstalling the barrel to see if all stays the same. Just my thoughts, but I don't own that model gun.

I would think super glue would be a bit much. offhand thought. drip some candle wax on it? idk maybe worth a try.

Thanks for brainstormin' with me folks. Good thoughts - both.

How about a squirt or two from a hot glue gun?

Put Blue Lock-tight under it and sight it in before the lock-tight cures.

Once it cures, the sight won't move by accident again.

I posted this on a couple of other boards as well. That is three votes now for Blue LocTite.

It won't eat the plastic, will it?

 

[rcmodel]

Not that I know of.

Take the sight off and test a small drop on a toothpick on the bottom of the sight.

But I would be very surprised if it hurts it.

Gun cleaning solvent is pretty strong stuff, and the sight has to withstand that.

[Danny Creasy]

Good suggestions. Will do.

Thanks.

AFter I sighted the AR7 in to my satisfaction at 25 yards I'd take a small dollop of JB weld and mold it up to the top of the sight BASE on each side. Then again I am a survivalist.

Why are my Mondays never like this???

Danny,

I bought a Kel-Tec 9mm folding carbine many years ago. Now KT makes good reliable guns, but the insides of their barrels can leave a bit to be desired.

This carbine was no exception. The best it would do at 25 yards was between four and six inches.

I looked like the perfect candidate for some fire lapping, so I did. Groups with the same ammo went down to an inch or less.

I would think that your AR-7 would fall into the same category: a good gun with a bore that leaves something to be desired. Fire lapping a 22 is very easy and it might pay big dividends for you.

Interesting.

I have fire lapped several rifles over the years:

A custom .45 ACP bolt action based on an old vz24 action. It shot jacketed bullets well before the treatment, but it tightly grouped both jacketed and lead cast bullets afterwards.

A 1903 Springfield with a very rough bore. Not much better accuracy but a lot easier to clean.

A Remington 541-T that scoped as a "rough" bore. It did seem to shoot better afterward.

I think it would be a little invasive to fire lap the AR-7 at this point. I'd rather shoot it for a while. Anyway, it looks like it we could easily hit a small game animal in the head at 15 yards.

I just consulted a construction guru about the front blade. He says clear silicone for exterior home use. But he gets it at work for "free" and is a cheap old skinflint.

One thing about the Silicone is that if you mess up just peel off the old and start over. Not permanent.

You could drill down through the front sight at a 45 degree angle and put a tiny set screw in that snugs against the sight base. Then it is secure but can be later adjusted.

 

[fireman 9731]

I have put a small brass shim under dovetailed sights before to snug them up. I just cut up and flatten out a fired 22lr case. That might work here and wouldn't hurt anything or be permanent.

Fireman 9731 said "I just cut up and flatten out a fired 22lr case."

Good suggestion.

Thanks,

Danny

irons

I just bought a cz 452 lux with the hump back stock. Researching this type of stock I found its purpose is to lower your eye to shoot irons. I t seems to work. The previous owner had a huge Tasco in high rise mounts. It was very difficult to use. If one really wanted an iron sighted tack driver this type of stock might help.

Absolutely
