HK paddle release install. Price runs $139, only the stripped barreled receiver is needed. Contact points are stone smooth, installation done per ATF specs with 1/8th pin. Step down padddle release bushing is a fully machined on a lathe, not a cheap modified harware store add on.
Paddle release runs $15.
Mag catch contact point, some rifles have it, others do not. Look in the back end of the mag well. If there is a small 3/8" protrusion sticking down from the magazine shaft, you're good.
Otherwise an additional $25 is needed to supply this part, I have all needed parts in stock.
Priority Mail return postage is included in all prices!
