hi everyone, ive been off the forum for about 1.5 years now and figured it was high time i came back!
at the last gun show i ended up coming home with a "cheap" ar15. ill explain...
at the RK gun show in knoxville i met a few guys fro red river guns out of the middle tennessee area, they had there booth set up with huge stacks or ar15 parts so they got my attention. they had 4 rifles set up pre-built to show the options of what your could build with them, 762, 556, 6.8 were the calibers to be had, all the parts seemed to be from Anderson mfg out of KY. the price for a hbar profile 1/9 twist 556 with freefloat was 579.00, the kit comes almost completely dissembled, the only thing assembled was the upper receiver dust cover and forward assist.
i got everything home and wouldnt you know it, the upper to lower fitment is loose, common problem across the board. so i decided to try and fix the problem myself. rather than pay 9.99 at the LGS i decided to try a experiment instead. i have high quality ar's but this one will be living under my back seat of my truck to shoot coyotes on my farm when they show up!
***disclaimer***
i did this to tighten up the fitment and reduce the rattle, any accuracy improvements are a bonus.
things you need-
-hot glue gun
-oil, any oil really but i just used FP-10
-clay, modeling clay, playdough, really anything that will mold
-some way to hold the gun level and even
1-i started out by using my bench vice and a mag well block to hold my gun level. i didnt bother to dissemble the lower, the modeling clay will keep everything out of the important parts.
2-next i coated the inner walls of the receiver witha thin coat of FP10 oil to act as a release agent.then i used some modeling clay to create a damn to prevent the hot glue from flowing into the receiver and jamming up the safety.
3- i then remounted the upper receiver with the front take down pin only.
4- the whole time the i had my glue gun preheating and ready to go. i then evenly coated the inner walls and floor of the receiver with a large amount of hot glue, being sure to cover the sides and rear of the receiver and filling the floor all the way to the bottoms of the take down holes. this will be more that enough to do the job.
5- this part will need to be done fast! due to its nature hot glue, cools off quick! and becomes hard quick. you will have about 15-20 seconds to mount the upper receiver to the lower and press in the take down pin.
6- after about 2-3 mins the glue will be cool enough to disassemble the ar, it may take a bit of force to get it unstuck but it will come undone. what you are left with is a perfectly molded "wedge" that will not move out of place.
7- remove the molded wedge and trim it down to size.
after triming
once i was finished i was surprised just how well the wedge stayed in place, due to its rubbery nature of the hot glue, it flexes and bends easily so removal is easy but it wont fall out or move when you clean your gun. hot glue also has a fairly high melting point and can take quite a beating at that, i have ran a few hundred rounds on this set up and no change what so ever!
so if you were thinking about a "accu-wedge", this could be a alternative.
