ak receiver flat with rails installed building

The Tapco's, likewise, tend to be too wide. If you like your receiver to be bow-tied then go right ahead and use the AK Builder. I put in 3 center supports this weekend and would test fit each of the three center supports in each receiver to find the best fit, and it was never the AK Builder. No matter how you do the theortical math, the DPH & Tapco center supports tend to fit the best. I have a stash of Tapco rivets/center supports, same for AK Builder and DPH. I too have found that Tapco Rivets are too short but so are AK builder Center Supports. Well it would be nice if someone offered the whole package deal at a reasonable price. The rest of what Curtis sells is top-notch, but he needs to acknowledge that a batch or two of his center supports is apparently shorter than it should be. Curtis refuses to believe that anything of his is causing the problem, even though his center supports are measurably shorter than Tapco and DPH center supports (which are both of the correct length). We got several receivers that were drawn-in in the middle. We had the same problem using AK-Builder center supports, AK-Builder flats, AK-Builder rivets, and all AK-Builder jigs.

Don't bother trying to tell Curtis anything's wrong, because he will tell you (in a 45 minute long-distance conversation) that nothing he sells is defective, and you must be doing something wrong. His center supports are shorter than normal, and is resulting in receivers being pinched in more narrow in the middle, which is causing bolts not to slide properly.

This product was added to our catalog on Tuesday 19 September, 2006. Look up a local machine tool supplier in your area to purchase them. A drill bit only has two flutes and a reamer has several and will center up on the hole better than a standard drill bit. These flats will need to have the hammer/trigger 5mm & 7mm holes enlarged with a reamer. They all copied another flat that was dimensionally incorrect and these were reverse engineered from an actual receiver. You can't buy flats and rails of this quality from any other manufacturer. The right side rails are also like the original rails that have the bump on the rail to center the hammer in the receiver. The ejector rails will now be longer like the Bulgarian style rails from K-Var with the mag stabilizer which no other flat that is on the market has. The dimensions and hole placing are exactly like my other flats, but were made to be more affordable. These are made with the magwell pre-cut for 7.62 with no choice for 5.45 magwell openings.
