I painted my rifle in a flecktarn-inspired pattern using rattle cans and adhesive stencils. It came out pretty well overall, but I learned a lot along the way, especially about prep, colour choice, stencil adhesion and how easy it is to overcomplicate the process. I've got a table of links at the bottom of the post with all the resources you might ask me about in comments.

Unfortunately I didn't think to take photos of every stage of the painting process but as you can see it's not rocket science. The key thing is short, overlapping sprays and light coats. Build up each coat, maybe do 2 full coats of the whole object. Your finger will hurt at the end if you've done it right. Also this took me 12 hours to do in total, if you want an idea on timescale. It's applying the stencils that takes this much time I think. Doing a simple 1 coat and done from prep to drying takes 40 minutes (did a simple paint job on another RIF I have).

I only know this because as I began doing the black base coat, a spray painter at this garage had a word with me and showed me how wrong I was doing things initially (I never painted anything in my life before with spray cans). Definitely saved me a lot of wasted paint that's for sure!

Disclaimer: I did use AI to generate this post initially, then tweaked it and I also used AI to prompt my way around getting the process right before I went ahead with it. I like to do things right first time where possible. I'm writing this post mainly for someone like myself that's not sure how to do something like this and what I found was the best way to do it. Maybe you have different ideas, I'd love to hear them.

Legal disclaimer: If you have a two-tone do not do this unless you have a UKARA number as technically it's manufacturing a RIF in the eyes of the law and very naughty, comes with fines etc. The UKARA is your valid defence. With that out of the way, let's get to the fun bits.

Materials I used

Paints: FOSCO military spray cans

I used FOSCO matt military spray paint. The colours I used were:

Colour	Use / notes
First coat: Flat Black	Base coat / darkest layer
Second: Flecktarn Braun	Brown flecktarn layer
Third: NATO Green	Looked greyer than expected
Fourth: DDR Green	Better dark green option for the look I wanted
Final: Flecktarn Grün	Came out brighter/lighter than I expected

The final coat ends up being your dominant colour when painting with stencils. I would swap my fourth and final layers around to get a better, darker flecktarn finish personally.

Stencils

I used Freedom Stencils German Flecktarn stencil kit. They are adhesive, single-use style stencils designed for spray paint, Duracoat/Cerakote type jobs etc. You want a hobbycraftish knife to lift and place the stencils ideally.

Prep / cleaning

I sanded with 400/600 grit all the surfaces I wanted to paint, wiped clean with a lint free cloth and isopropyl alcohol. Masked off where I didn't want paint getting to, then hit with Hycote Adhesion promoter. I would recommend having multiple cloths handy for the cleaning stage as if you're doing a two-tone they will end up very whatever colour your paint is with the alcohol clean stage. You could potentially try wiping a lot of it off before you start painting.

The prep is the worst part really. For the black basecoat I personally stripped the rifle and painted everything individually then reassembled for the stencil coats.

Oh also, you can hang with zip ties. That's what I chose to do and if you have any surfaces that are hidden by zip ties, just gently grab and manipulate the RIF to get access to the parts you need to paint.

Remember to mask your inner barrel/magazine well/places where BBs go etc

Useful extras:

Item	Why
Lint-free cloth / blue roll	Better than fluffy kitchen roll
Masking tape	For areas you do not want painted
Nitrile gloves	Stops skin oils getting back on the rifle
Heat gun or hair dryer	Helps warm stencils and reduce lifting, can also speed up drying of paints between coats
Matte clear coat/lacquer	Protects the finish, but test first

Main lessons learned

1. Prep matters more than the paint

The paint job is only as good as the surface underneath. Clean the rifle properly, degrease it, and avoid touching cleaned surfaces with bare hands before paint. Oil, silicone, grease and skin oils can all mess with adhesion.

2. Do not rush stencil adhesion

The biggest issue I had was underspray from stencil edges lifting. Flecktarn uses lots of small shapes, so there are loads of tiny edges that can lift. Press every stencil down properly, especially around curves, corners, rails and textured polymer.

What I’d do differently:

• Warm the stencils slightly before applying.
• Press the edges down properly.
• Avoid stretching them over awkward shapes.
• Use smaller pieces on curved areas rather than trying to force big stencil sections to conform.
• Spray lighter passes to reduce paint being blasted under the edges.

3. Light coats beat heavy coats

Heavy coats make everything worse: runs, bleeding, raised paint edges, longer curing time, and more chance of lifting when removing stencils. Several light passes are safer than trying to get full coverage in one go.

4. Colour choice is everything

The biggest aesthetic lesson was that the final colour balance depends heavily on the last/top layers. My lighter green came out brighter than I wanted, so next time I’d bias the job darker.

For a darker woodland/flecktarn style, I’d lean more toward:

• Flat Black
• Flecktarn Brown
• DDR Green
• Possibly NATO Green, but carefully, because it can look greyish
• Use the brighter green sparingly, or skip it if going for a darker rifle

For my next dark green rifle, I’d probably use DDR Green as the main green rather than relying on NATO Green.

5. Think about the order of colours

The later layers dominate the finished look. If the final/top colour is too bright, the whole rifle can look brighter than expected even if the base layers were dark.

6. Paint disassembled where possible

I sprayed mine fully assembled and I found that the hop adjustment access/dust cover wasn't staying shut after the fact. I think the tolerances on my rifle were tight so I ended up having to sand a bit of the paint away to get it sitting nicely again.. It worked, but it is not ideal.

A trick I used around my safety was to mask that area with stencils in one of the earlier paint applications. Oh also, removing the safety on this particular M4 was a nightmare, I do not recommend it. Just paint around it and don't go crazy like me trying to get a 90 degree screwdriver that fits!

7. Test on scrap first

The colours on the cap/listing do not perfectly represent how they’ll look on the actual rifle, especially over black or other base colours. A quick test on cardboard/plastic would have made the final colour balance more predictable.

8. Let layers cure properly

Touch dry is not the same as cured. If the paint is still soft, stencils can mark it, pull it, or leave adhesive residue. Cold weather also slows everything down. I made the mistake of picking the rifle up when the paint was still in it's drying phase and have a handprint mark around the grip as a result.

9. Clear coat is useful, but keep it matte

A matte clear coat helps protect the finish, but too much can make the rifle look slightly shiny or plasticky. Light coats are the way to go. Test compatibility first so the lacquer does not react with the paint.

10. Flecktarn is fiddly but forgiving

Because flecktarn is naturally busy, small mistakes disappear into the pattern. Underspray and imperfect edges are annoying up close, but once the whole rifle is assembled and used outdoors, most of it blends in.

What I’d do differently next time

• Use DDR Green as the main dark green.
• Use the bright green much more sparingly.
• Press stencil edges down harder and use smaller stencil sections on awkward shapes.
• Spray lighter coats from slightly further away.
• Disassemble or mask controls properly.
• Do a colour test card first.
• Give each layer more curing time.
• Lacquer after the paint has properly hardened, not just dried.

Scrim is fun

Get on alibaba and get yourself some cheap flecktarn pattern netting and cut it to fit the rifle to achieve the look I have in the final final photo. It was mainly to dull the colours down a bit because of the brightness of that blasted flecktarn grun, I think it adds a lot to the rifle but it is a very fiddly thing to get right. Worth the time spent though, IMO. What you see in the final image is a bit of netting, cut to fit the gun and give access to controls, held on with paracord.
