This build has approximately 800 rounds through it and has consistently had an issue with the slide not fully going into battery after a few boxes of ammo.

This presents two ways:
The slide stops with about 1/4in to go
The slide stops with the round half way into the chamber

In both cases pressing on the rear of the slide with my thumb is enough to get it to finish going forward. Prior to switching to the 20lb spring I could get the first scenario to sometimes happen just by slowly moving the slide forward and letting it get “stuck.”

The first 600 rounds were with an OEM recoil rod/spring. I switched to the 20lb spring and slip2000 for lubricating the slide for today’s range trip.

It was perfectly clean before the range trip. I think the slip2000 got slung around and captured a bunch of carbon. Put 200 rounds through it today. The slide issues happened 4 times (which is an improvement).

I don’t see any excess carbon build up in the chamber and the feed ramp wipes clean and is very smooth. No signs of obvious wear marks on the slide or frame.

Does anyone have any ideas for what I should check next on this build? I’m going to get it cleaned up this evening and take another look at things.

This is a follow up to my last post about rifle selection a mini review of the Muenster, Tx event.

First off, thanks for all the feedback on my rifle questions. I ended up getting my rifle down to about 4.5lbs. Didn’t feel the weight at all during the event so I think that worked out well.

It ran like a champ, not a single feed issue or round not going off. There were 3-4 rifles that didn’t make it through the entire event due to jams, scope malfunctions, and an even squib load.

Final build:

Magpul X-22 MOE (OD Green)

Ruger action/barrel/trigger (Painted Coyote brown)

Auto bolt release

EGW extended rail (Painted Coyote Brown)

Vortex Crossfire HD 2-7x32 and Vortex rings (Going to paint when I have time)

My background: I’ve been shooting off and on for about 18 years, primarily pistol, but rimfire rifle from the bench at 50yrds for the past few years. No formal training. I’d consider myself a slightly above average shooter. I’m also a somewhat rotund individual that works a desk job and hasn’t worked out in almost 6 months (this will come into play later).

Event:

The shoot boss (Scott) and instructors in training were fantastic. Friendly, informative, well spoken, helpful, and many other positive adjectives.

This event was so much fun. All the attendees were pretty chill, supportive, and not political which is a huge change from the few shooting events I’ve attended in the past. We had 6 people get expert and 1 get distinguished marksman.

Learning how to use the sling was a game changer and I can’t wait to start practicing more standing rifle shooting at my regular range (I don’t have any close ranges for prone). My previous attempts at unsupported standing groupings looked more like bird shot than rifle rounds 😅.

Day 1 I fought with eye relief and cheek weld issues. I couldn’t get a stable position for my head at all. When I got home that night I 3d printed a butt stock extension to fix the eye relief and taped on a washcloth as a makeshift cheek riser. I had almost no issues getting into a reliable head placement after that.

Day 2 I was able to focus on body positioning now that my head was locked in. After several practice sessions I finally had my sling in the sweet spot that worked well for prone and standing, needed a minor adjustment for sitting. I saw some good improvements in my groupings and mainly need to focus on consistency. If I can cut down on flyers I should be able to qualify next time.

AQT Scores: 185, 196, 196, 197.

My advice for other first timers:

1. Check your scope hardware, clean your rifle, and put some rounds down range the weekend before to make sure your rifle is ready.

2. If you’re out of shape or just sit at a desk all day, do some stretches the week leading up to your event. My back really did not like stage 4. I was super stiff and had to sit for a minute for things to loosen up.

3. Long sleeves or elbow pads are a must. I shot our last two AQTs with my jacket off and rubbed my elbows raw.

4. Drink a bottle of water every time someone reminds you even if you think you’ve been drinking plenty. I didn’t feel dehydrated until I was on my way home and I’m paying for it now. Leg cramps are not fun.

5. Just show up, listen, and have fun.
