| Have the A1 stocks H&R is using for rifles changed? Linemount's website says they are now foam filled like the originals and I believe I read something similar to that in the reviews on the H&R website. Just curious. I have an original Colt A1 stock and it feels better IMHO. |

| I bought a Type E from Argent Wolfz about a year ago. They are Taiwan-based, I believe. The stock was every bit the quality of a new GI stock. Foam filled, metal door and all of that. I was very impressed. Their web site is a little confusing to maneuver through. That is the only drawback. Edited to add - I just looked at the Linemount Type E. Says "Made in Taiwan." I bet it's the same stock as the Argent Wolfz. |

I putt my stock in the vice when I did it just to keep it contained while I sprayed and to give it a place to dry. I did three or four of these as I recall. I'd have to go pull butt plates and check now to be sure. The pics I added below reminded me: I just rotated the butt plate out of the way and left the buffer tube inserted so that you don't fill up the buffer tube cavity! I used THIS stuff, which I seem to recall was recommended either here or one of the other retro forums at the time. I did this back in 2023 according to my Amazon orders. :-p |

| If you do decide to foam-fill a stock, THIS was recommended in one of the discussions. It expands less than the standard foams, and is therefore denser/more solid once it cures. I have not used it myself, but wanted to make you ware of an alternative. |

FYI - If you fill up the entire cavity in one shot, the gasses have nowhere to go and will result in a giant voids. I've filled up three Brownell's stocks with foam and have taken apart two of them. The result was material stuck to the walls of the stock in random thicknesses and the rest was open air. Most spots were so thin you could easily see through the material. I just recontoured two stocks for Proto projects a couple weeks ago, and thought about taking pictures, but then thought the subject would never come up. This wasn't surprising to me as a couple years ago I repositioned a door I had formerly installed and noticed that even though I practically used the entire can of foam around the gaps, most of the gap was just giant air pockets connecting the interior to the exterior skins of the foam. The solution is build up layers like welding beads. Spray a layer, let it skin over, spray the next layer and so on. This way is can outgas. |

I foam filled a Brownells stock. I think i used Red Devil expanding insulation foam. It was in a thread I started about the Brownells stock. I cant remember who gave me the advise to grease the buffer tube, but it worked. In the past I did several AK stocks from KVAR. They were easy. Not a difficult project at all. For some reason it seems I may have wrapped the buffer tube with Saran Wrap they covered in a lubricant. |

Still no idea why they dont connect the sling swivel and butt plate the way they should be. |
