Any sources for 33 kits that you know of? The only place I have found so far is HKParts.
I thought that might be what it was but I have some tough hands and I don't think I could put the gun in battery with it. hah. looks kinda cool.That's the thumbprint cut you use to force the bolt closed in case you let it down too softly. Low-dollar forward assist.
Glad to hear that they were able to complete your order.Mags are not included in their kits. They sent the forearm and boltgroup without question. Only crappy part is I ordered a couple mags from them and had to pay like $20 shipping to cover the parts they forgot cause they bundled it together. O well. Least I got my parts. I am satisfied.
